Scientists Explain Why Stainless Steel Corrodes: Scientific American

Scientists Explain Why Stainless Steel Corrodes: Scientific American: Scientists Explain Why Stainless Steel Corrodes

By Sarah Graham

Stainless steel's resistance to rust makes it one of the most useful and widely employed metallic products. It is not infallible, however. The material can succumb to so-called pitting corrosion, in which highly localized defects weaken the steel, often with disastrous consequences for applications such as industrial pipes and tanks. Now researchers writing in the journal Nature think they know why this happens. Their findings may help pioneer techniques for minimizing corrosion in the future.

Atoms contained within the stainless steel alloy, particularly chromium atoms, supply its rust-resisting power by reacting with oxygen to form a protective film. Previous research into pitting corrosion had placed the blame on sulfur-rich impurities in the alloy. In the new work, Mary P. Ryan of Imperial College of Science, Technology and Medicine in London, England, and colleagues demonstrated that the impurities do cause the corrosion, but indirectly. Borrowing a technique from microelectronics, the team examined the metal around sulfur-rich impurities and found that those regions had significantly less chromium than the rest of the steel. As Roger C. Newman of the University of Manchester Institute of Science and Technology explains in an accompanying commentary, "The dip in chromium content around the inclusion weakens the alloy's protective oxide layer, making it vulnerable to corrosion."

The chromium-depleted pockets less than 400 nanometers across but responsible for many catastrophic failures, according to the report form during the steel fabrication process. Because the sulfur impurities solidify at a lower temperature than does the steel, they remain molten for a period after the metal has solidified. These molten spots suck the chromium from the surrounding steel. "We've worked out the sequence of events that cause [pitting corrosion], we know what causes this Achilles' heel, and we can use this information to work out how to fix it," Ryan says. Indeed, Newman suggests that "unconventional heat treatments, designed to diffuse chromium back into the depleted zones," could improve the corrosion resistance of stainless steel.

Does heating with wood cause global warming ?

What about local air quality ?

Does wood heating harm the forest ?

Is wood heating safe?

Good questions. Real Answers.

By heating with wood you do not contribute to the greenhouse effect as you would by heating with one of the fossil fuels like oil and gas. When oil and gas are burned, carbon that has been buried within the earth for thousands of years is released in the form of carbon dioxide, a by-product of combustion. The result is an increase in the atmospheric concentration of carbon dioxide, the cause of the greenhouse effect.

Although carbon makes up about half the weight of firewood and is released as carbon dioxide when the wood is burned, it is part of a natural cycle. A tree absorbs carbon dioxide from the air as it grows and uses this carbon to build its structure. When the tree falls and decays in the forest, or is processed into firewood and burned, the carbon is released again to the atmosphere. This cycle can be repeated forever without increasing atmospheric carbon. Heating with wood, therefore, does not contribute to the greenhouse effect. And there’s more good news: when the use of wood for energy displaces the use of fossil fuels, the result is a net reduction in greenhouse gas emissions.

Wood is not an inherently dirty fuel that causes serious air pollution. While it is true that old technology like open fireplaces and simple heaters could not burn the wood completely, the new generation of woodburning appliances produce almost no visible smoke and deliver efficiencies in the range of 70 percent. Developed since 1980, improved technology has cut particulate emissions (smoke) by about 90 percent compared with conventional equipment. Wood may not be the best fuel choice in densly populated urban areas where automobile exhaust and other pollution already puts excessive strains on the air shed. But in suburban, small town, and rural areas, wood makes good sense.

Wood contains only a negligable amount of sulphur, an element that leads to acid rain. In this age of environmental awareness, a big advantage of wood over the fossil fuels is that its main environmental impact occurs at the point of use and is visible for all to see. In contrast, the real environmental impacts of oil and gas are hidden from view because they occur during extraction, refining and transportation of the fuels to market.

If the destruction of tropical rain forests causes global warming and if planting trees in your community is a good strategy control greenhouse gas concentrations, then how can using wood for home heating be justified? Good question. The answer lies in the natural cycle of growth, maturity, decay and re- growth of trees and forests. A healthy forest is not a museum, but a living community of plants and animals. When trees are used for energy, a part of the forests carbon “bank” is diverted from the natural decay and forest fire cycle into our homes to heat them.

The key to ecologically sound and sustainable wood energy use is to ensure that the forest remains healthy, maintains a stable level of variously aged trees and provides a good habitat for a diversity of other species, both plants and animals. You can do your part by insisting on firewood that is harvested using sustainable forestry practices. Ideally, buy your firewood from the person who owns the woodlot because owners are less likely to damage their forest. If that is not possible, question the seller about the origins of the wood.
image
When thousands of families turned to wood heating in the late 1970s and early 1980s to shelter them from high energy costs and the threat of shortages, there was a sudden increase in the number of house fires related to wood heating. Wood heating acquired a bad reputation, mostly because neither the users nor industry had reliable guidelines for installation safety. Since then, however, the wood energy industry and all levels of government have worked together to put in place the same type of safety systems as have been in place for other heating fuels for more than 30 years.

The product safety standards, installation codes and professional training for installers and inspectors have resulted in a greatly improved safety record for woodburning. Installed according to the codes and used according to the manufacturer’s instructions, woodburning appliances are no more hazardous to use than any other form of home heating.

Note from Hawken Energy: Outdoor wood furnaces remove danger of a home fire by moving the combustion outside and requiring caps on the chimneys. Not all outdoor wood furnaces are the same. Ask your local Hawken Energy Factory Rep about the differences and why Hawken is the safest choice.

“The supply of firewood from privately managed wood lots to residential users of the fuel represents an important but neglected model of sustainable development. An increase in the use of wood as a fuel for residential heating can occur within the framework prescribed by current principles of environmental sustainability.”
Dr. O.Q. Hendrickson, Forest Ecologist

“. . . it is extremely important to note the fundamental difference between biomass (wood) and fossil-fuel sources of (carbon dioxide) emissions. . . . . To a large extent, bio-related emissions would occur even in the absence of human intervention.”
Canada’s Greenhouse Gas Emissions: Estimates for 1990, Environment Canada report.

“Forests are constantly thinning themselves, and there is much evidence that tells us that we could prudently be thinning our forests for millennia if we attended to its rhythms and patterns.”
Paul Hawkin, Author, The Ecology of Commerce

“Wood is a renewable resource, and, because trees recycle carbon dioxide, wood burning does not contribute to the global warming problem.”

Senate approves outdoor wood boiler bill

Senate approves outdoor wood boiler bill � Local News � Press-Republican:

Senate approves outdoor wood boiler bill

WITH BOX By KIM SMITH DEDAM Staff Writer

THE SENATE BILL



RAY BROOK — A law counteracting proposed state regulation of outdoor wood boilers was approved unanimously in the Senate this week.

A similar bill awaits Assembly vote.

The measure allows for continued use of existing outdoor wood furnaces, displacing regulations now under review by the New York State Department of Environmental Conservation.

The Senate measure drew praise from local officials and wood-boiler owners.

WIN FOR RURAL AREAS

Senate bill S8061 "finds that because of the wide variation in climate, topography, community character and socio-economic conditions throughout New York state, any regulation of outdoor wood boilers that is more restrictive than that contained in this act is most appropriately left to local governments."

Co-sponsors Sen. Betty Little (R-Queensbury) and Sen. Darrel Aubertine (D-Cape Vincent) see Senate approval as a win for rural New York.

"The bill would allow for the continued use of outdoor boilers currently in operation, require any new boilers sold in New York be EPA approved and allow for local decision-making with respect to zoning issues, such as setbacks and chimney heights," Aubertine said in a statement after the vote.

WOULD STOP DEC PLAN

Jeff Palmer, legislative director for Aubertine, said that if the bill becomes law, it would more or less prevent DEC regulations from going through.

"We're saying we don't want the phase-out of existing outdoor wood boilers and that the zoning piece belongs to the towns."

DEC spokeswoman Lori Severino said they don't comment on pending legislation, especially since DEC's regulation has not been finalized.

Should the outdoor wood boiler bill become law, that would supercede DEC regulation.

MISCONCEPTIONS

"Then our regulation would have to conform to the state law," Severino said. "Ours is just being proposed right now. When it goes out again for public comment, probably in a couple months, there will have been changes made.

"We're not banning wood boilers. That's been the main misconception at all the public hearings. What we are doing is proposing regulation to ensure that outdoor wood boilers are being properly used and burning as cleanly as possible.

"The overall goal is to be protective of people's public health and the environment."

DEC's proposed rules set stack heights at 18 feet and would require existing furnaces to be replaced in 10 years. It also establishes blanket setbacks and site restrictions for every municipality in the state.

OWNERS THRILLED

Almost 20 North Country residents had objected to the proposed DEC regulations at a public hearing in Saranac Lake two weeks ago.

Tom Gallagher, who runs a small farm on 70 acres in Malone, has been heating his home and hot water with an outdoor wood furnace for nine years.

He was glad to hear Friday that the Senate legislation passed.

"I have had no objection to some kind of control over wood boilers," Gallagher said. "I just don't support the heavy-handed way this has been brought through DEC. It was not properly conceived — you can't have one-size-fits-all regulation for the entire state. The towns know best what's good for their municipality."

In Lake Placid, resident Norm Bradley installed an outdoor wood boiler six years ago at a cost between $9,000 and $10,000.

Phase-out after 10 years does not seem feasible, he said.

"That is frankly remarkable," Bradley said about the Senate action. "I am overjoyed because (DEC regulation) just doesn't pass the common-sense test.

"The first year my wife, Bobbie, and I had the boiler, we were city people. We put wood in there, sometimes it was wet; but after a while you learn, you use it intelligently, and it can be controlled very easily.

"But this is a local issue. It's not an issue for mid-town Manhattan."

PRESSURE

The New York Farm Bureau is continuing to pressure Albany to stop the DEC regulation.

"The problem is the Assembly has to pass the same bill, and the governor would have to sign it," Farm Bureau spokesman Peter Gregg said Friday.

"Until that happens, we're still staring down the barrel of new DEC regulations that would severely impact the heating resources of many rural New Yorkers. DEC is still moving forward with these at least 'proposed' regulations. That train is still going down the tracks. In the meantime, we're going to continue to vigorously lobby to stop the DEC rules from going through."

IN COMMITTEE

Assemblywoman Teresa Sayward (R-Willsboro) said the bill is in the Environmental Committee and likely won't be worked on until January.

"I do know from talking to some of the Assembly members that they are trying to work with the Farm Bureau to come up with changes to the regulations that would satisfy their concerns. We understand there needs to be cleaner emissions, but we want them to leave the people alone that already have these devices.

"Further, we want the localities to decide where these go, because every community is different."

Letter to the State of New York Concerning Outdoor Wood Boilers

June 16, 2010

John Barnes, P.E.
New York State Department of Environmental Conservation
Division of Air Resources
625 Broadway
Albany, NY 12233-3251

Re: Proposed Revision of 6 NYCRR Part 200, General Provisions and
Proposed Part 247, Outdoor Wood Boilers


Dear NYSDEC:

The following comments are being provided in response to Proposed Revision of 6 NYCRR Part 200, General Provisions and Proposed Part 247, Outdoor Wood Boilers (“OWBs”).

In summary, we strongly urge the DEC to NOT adopt the proposed rulemaking (“Proposal” or “Regulation”) for the following reasons:


1. The Proposal will severely damage the economy of the State of New York by killing jobs, and by increasing heating costs by over 400 percent for many businesses and homeowners.

2. The Proposal will expose the DEC and the State to a potentially enormous legal liability associated with deaths and injuries resulting from carbon monoxide poisoning and house fires.

3. The Proposal will dramatically increase the emissions of greenhouse gasses.

4. The State consists of largely rural areas where outdoor wood boilers (OWB) do not impact anyone. Broad regulation of OWB throughout the entire State would be overly burdensome to citizens in most areas of the State. Therefore, any necessary regulation should be established at the local municipal level in densely populated areas only.

5. Establishing a stack height, phase out and seasonal operating limitations pertaining to existing OWB is ridiculous and unconstitutional.

6. To require an OWB owner to replace his legacy OWB or permanently remove his OWB by 2015 and no later than 2020 is unconstitutional and will be challenged in the courts.

I will now provide the following data to substantiate the above points:

1. Qualifying Model Cost:
The proposed rulemaking requirements would require a Phase 2 models which are more costly than traditional OWBs. Note the table below that compares a Standard OWB to a “Cleaner Unit” – this table shows that the “Cleaner Unit” costs 72 percent more, AND it produces less than HALF the amount of heat!

Comparison Standard OWB “Cleaner Unit” Disadvantage of “Cleaner Unit”
Example Model Hawken Energy
HE-1100 Central Boiler E-Classic 1400
EPA Phase 2 Certified? No Yes
Retail Price $5,595 $9,630 72% Higher cost
BTU Output 225,000 BTU/hr 107,500 BTU/hr 48% of the BTU output

Result of this Regulation? NY CITIZENS WILL BE BURDENED WITH SUCH HIGH COSTS FOR THESE “CLEANER UNITS” THAT THEY WILL LIKELY NOT BE ABLE TO AFFORD THEM. As a result, more fossil fuels will be burned in the State, thus creating more greenhouse gas emissions. Fossil fuel costs are much higher than biomass (wood) cost. Our State consists primarily of heavily-wooded, rural areas. It makes no sense to burden the citizens of our entire State with a rule that really only applies to a few densely populated areas that comprise a tiny fraction of our State.

2. Cost of Chimney Stack Extensions
The proposed rulemaking attempts to convince the reader that the cost of becoming compliant with their new stack height requirements would be minimal. This is completely false. An average cost for a homeowner to make this modification to an existing OWB would be $815.00.

A proper cost analysis would need to include the following parts:

Part Average Cost
Adapter/Collar $36.00
Triple Wall Extension piece $462.00
Roof bracket $48.00
Chimney Tee $162.00
Tax $40.00
Installation $100.00
Total $848.00

Result of this Regulation? This high cost of compliance with the ordinance will force citizens to ignore the Regulation, shut off their OWBs and burn fossil fuels, or bear this high burdensome cost to become compliant with the Regulation.

The Proposal Will Severely Damage the Economy of the State of New York

3. Burning Wood Saves Money for Businesses and Homeowners
Per Btu, wood is much less expensive than fossil fuels – at current prices, natural gas is three times the cost of wood, propane is five times the cost of wood, and electricity is seven times the cost of wood . Does the NYSDEC really wish to subject the citizens of New York to the high cost such expensive fossil fuels, or the high cost and low output of EPA-approved devices?

The high cost of energy for home heating has financially crippled many homeowners nationwide. The State of New York should be looking for ways to provide its citizens a way to stay warm in their homes, without facing financial disaster.

4. Burning Wood Helps the NY Economy by Saving Jobs
The harvesting and burning of wood is an important economic factor in New York.. It reduces our dependence on foreign energy companies and it supports our local economy. There is no billion dollar wood fuel utility that will profit from wood burning or multinational corporations involved in the wood heat business. Most businesses that supply furnaces are small manufacturers and retailers. Local workers who chop firewood and chimney sweeps who service wood-heating systems get the benefit of local dollars.

Hawken Energy has 13 Authorized Factory Representatives in the State of New York who support their families at least in part by selling and installing Hawken OWB. Many of these Reps have employees working for them as well, all of whom would face the possibility of losing their livelihood should the proposed Regulation be adopted.

Does the NYSDEC really want to eliminate more jobs in the state?

Result of Regulation? New York will lose many jobs to big foreign oil companies.

5. This Regulation Would Harm the NY Economy Because of Its High Cost of Compliance
See Sections 1 above. Note that given the extremely high cost of “EPA-approved” devices, very few units are being sold. One company that sold only EPA-approved devices, Greenwood Technologies, has gone bankrupt and is currently liquidating its assets. Again, these units cost much more – in some cases they are twice the cost of standard OWB – and they typically produce less than half the BTU output. Therefore their excessive cost would overly burden citizens of the State.

The stack height requirement would also overly burden citizens of the State with very high compliance costs. See Section 2 above.

6. This Regulation Would Harm the NY Economy Because It Does Not Consider The Forecasted Future High Cost of Fossil Fuels
What fuel will be used when the world runs out of oil – which is expected to happen within 50 years? The world is running out of fossil fuels. In a few years, the world’s inhabitants will have consumed one-half of the known fossil fuel reserves. Once this happens, fuel prices will skyrocket as fears of “running out” will become more of a reality.

“The volume of the world's petroleum reserves is important because of the fear that the oil will run out. This fear should be expected, because the estimated remaining one trillion barrels of crude oil is only enough to supply the world for about 50 years. This prediction is based on the present world consumption; however, world consumption is expected to increase.”

Within 10 years, experts project the world oil demand will exceed production capacity by 20 million barrels per day. This will result in astronomical fuel prices to level the supply/demand curve. NY homeowners will be forced to find and pursue alternative heating methods; low-cost wood and other biomass fuels will enable NY homeowners to heat their homes without becoming financially crippled, unless your proposed Regulation is adopted.

See footnotes below for more information on the reality of “peak oil ”

Result of Regulation? Such Regulation, if adopted without the foresight of expected future fossil fuel energy costs, will damage the NY economy, as home heating costs rise.

The Proposal Will Expose the NYSDEC and the State To a Potentially Enormous Legal Liability Associated with Deaths and Injuries Resulting from Carbon Monoxide Poisoning and House Fires.

7. Legal Liability
Given the cost of this proposed rulemaking on citizens of our State, many citizens will not be able to afford these high regulatory costs and will be forced to use indoor-fired heating appliances. Such indoor-fired heating appliances are dangerous – such dangers include, among other things, serious injury and even death from carbon monoxide poisoning and house fires.

Outdoor wood boilers take combustion outdoors. Therefore, households and businesses can reduce their insurance costs by using outdoor furnaces since outdoor combustion eliminates many risks of fire damage, and carbon monoxide poisoning.

Result of Regulation? The high cost of compliance with this Regulation will lead businesses and homeowners away from using wood as a fuel in an outdoor appliance. The result will inevitably be deaths and injuries from fires and carbon monoxide poisoning (among others) that will lead to costly litigation against the NYSDEC and the State. Does the NYSDEC or New York State really want to subject our citizens to the risk of death? And does the NYSDEC really want to subject our State to the cost of inevitable lawsuits resulting from such deaths?

The Proposal Will Dramatically Increase the Emissions of Greenhouse Gasses.

8. Wood is A Renewable Fuel
Wood has been safely used as a fuel since the beginning of recorded history – longer than any other fuel. Fossil fuels have only been used for heating since the early 1900s. Prior to this, wood had been the primary fuel for as long as Planet Earth had been inhabited by man.

Wood is a renewable fuel. One of the reasons wood is such a perfect fuel is because it is renewable. This means that it can be “restored and replenished by nature in a period of time that is compatible with our human use”. The heat released from wood is actually stored energy from the sun--released when consumed in a wood burning device. Wood is an abundant resource in this country that is easily sustained. Provided they are cared for and managed properly, our forests can be a perpetual source of fuel, unlike gas, oil, and coal, which are being depleted at a rate that is astonishingly faster than the millions of years it took Nature to make them.

9. Fossil Fuels Produce Excessive Greenhouse Gasses – Wood Does Not
Wood burning is completely safe in terms of “Greenhouse Gasses” - All fuels produce carbon dioxide, the primary greenhouse gas, when they burn. When the atmospheric concentration of greenhouse gasses increases, they cause the average global temperature to rise.

Wood differs from the fossil fuels coal, oil and gas, because it is part of the natural carbon/carbon dioxide cycle. As a tree grows, it absorbs carbon dioxide from the air and stores it in the wood as carbon, which makes up about half of the weight of wood. When the wood is burned, carbon dioxide is released back into the atmosphere. No additional carbon is released because the same amount of carbon dioxide would be released if the tree died and were left to rot on the forest floor. The carbon in coal, oil and gas, by contrast, are taken from underground stores, usually from overseas, where they were deposited by Nature, and released into the air without means for equal reabsorption.
When trees are used for energy, a part of the forest's annual growth is diverted from the natural decay and forest fire cycle into our homes to heat them. Firewood is a natural energy product from the forest. Burning wood actually helps reduce greenhouse gas emissions by displacing the use of oil, gas and coal.

The US Government states clearly that wood burning is not harmful to the environment in terms of Greenhouse Gasses: “Under international greenhouse gas accounting methods developed by the Intergovernmental Panel on Climate Change, biogenic carbon is part of the natural carbon balance and it will not add to atmospheric concentrations of carbon dioxide. Reporters may wish to use an emission factor of zero for wood, wood waste, and other biomass fuels in which the carbon is entirely biogenic.”

Result of Regulation? Since this Regulation dramatically increases the cost of using wood as a fuel, fossil fuel use will increase thus increasing the volume of harmful greenhouse gas emissions.

The State Consists of Largely Rural Areas Where OWB Do Not Impact Anyone. Broad Regulation of OWB Throughout the Entire State Would Be Overly Burdensome to Citizens In Most Areas of the State. Therefore, Any Necessary Regulation Should Be Established at the Local Municipal Level in Densely Populated Areas Only.

10. Common Sense
Unfortunately, there is some incorrect information being spread around about wood burning. We are unsure of the exact reason this information is being spread – perhaps the large foreign oil companies are threatened by wood burning, or perhaps people are just afraid of something new and different. When automobiles started to become popular, they were opposed by those who favored horses and buggies. Times change, we adapt to these changes, and we move on – this is progress and it is why we as Americans are so successful.

Those opposed to burning wood make it sound like wood is the worst fuel in the world, and that it is somehow dangerous. After reading some of this misinformation, one feels almost like they should seal up their fireplace and turn up the fuel oil furnace! After quiet reflection, however, one realizes that any argument that burning wood is somehow more harmful than burning fossil fuels is preposterous.

Though the use of any resource has an environmental impact, the use of wood as a fuel is much more in keeping with the natural cycles of ecosystem Earth. The heat produced by burning firewood is actually the warmth of the sun, stored in trees through the process of photosynthesis. When the sun abandons us during the cold dark days of winter, we liberate the sun’s heat through the “reverse photosynthesis” of burning. Like every other cycle in Nature, every process has its opposite.

Wood is a reliable fuel. In the midst of a winter storm when the power goes out or during an energy crisis rolling blackout, homeowners can still heat with wood. It gives both heat and comfort during times of emergency. Wood also gives freedom. Having the ability to burn wood for heat in a home gives more freedom and options for fuel. Many homeowners live away from natural gas pipelines and are forced to purchase much more costly fuels such as propane or fuel oil. Wood fuel allows a homeowner to no longer be dependent on large energy utilities that may or may not be able to supply energy.

Conclusion
In conclusion, the State consists primarily of heavily-wooded, rural areas. It makes no sense to burden the citizens of our entire State with a rule that really only applies to densely populated areas that constitute a tiny portion of the State. Any needed regulation should be left to local municipalities. Accordingly, we recommend that the NYSDEC NOT adopt the proposed, or any regulation of OWB. Such regulations can be easily managed by local municipalities of densely populated areas.

Please feel free to contact me with any questions you may have.

Sincerely,

Warren W. Walborn
