News: Power Plant Pollution Declines, but Autos Keep the Smog Around

Posted November 29, 2006 9:32 AM

From Scientific American - Official RSS Feed:

On a hot summer day, plumes of nitric oxide and nitrogen dioxide--collectively known as NOx--billow forth from coal-fired power plants in the eastern U.S. Along with urban concentrations of their transportation counterparts--think the tailpipes of cars and trucks--such plumes can be readily detected from space via orbiting satellites. And such space-based data reveals that NOx emissions, from power plants at least, are on the decline.

Power Plant Pollution Declines, but Autos Keep the Smog Around

11/30/2006 12:05 AM

AEP Tanner's Creek running 100% opacity is shown because AEP owns and markets for profit the credits to pollute. Cap and trade is a misnomer. Unless there is a shortage of credits (excess pollution) AEP can not market pollution credits. AEP engineers get fired if they cap.

AEP CEMS engineers know how to run AEP Tanners Creek clean as AEP Clifty Creek or Clinch River with 0-3% opacity. Operation at pollution limits creates a shortage of credits. With a shortage of pollution credits (excess pollution) Supply and demand increases the market value of pollution credits.

Power plant efficiency improves when NOx is converted to power rather than pollution very similiar to the nitrous boost a chevy engine gets during hot weather at the Texas drag strip. Tanners Creek capacity is an excess for the Cincinnati area renedering pollution credits more profitable for AEP than electricity at Tanners. AEP Clifty, on the other hand, has a government power contract to purchase every megawatt so AEP converts the NOx to megawatts rather than pollution at Clifty Creek. Follow the dollar.

Clean energy cost less than high pollution energy if the government incentives, grants, loans, study to pollute were eliminated. It is possible to generate off grid energy at a lower cost than grid power in most states but the convenience factor or comfort factor often control the decision rather than cost. Clean power is not as convenient as flipping the grid locked switch.

In my city of Estevan,Saskatchewan the government just gave approval to build a zero-emission coal fired plant. It is interesting how it works, It generates 450MW but 150MW are used to filter and clean and trap all the gas emissions. The trapped CO2 is then sold to oil companies in the area to help extract oil by forcing the CO2 into the ground. Therefor all the CO2 is actually placed directly back into the ground.

It may not be as efficient, but we have alot of coal around here and its nice that there will be one less smokestack in my area.

I am very pleased with the results in using a new product in my former smoke spewing, gas guzzling '94 Chev truck. Passed new California emissions test and increased mpg by 28%. For info: www.ecoenergizer.com/joeselig

JOB, WOW! $50 bucks for eight ounces?

Nanoeconomizer cost almost as much as gasoline. How do you justify the expense? Can you share your personal experience with the product?

What are the ingredients? Ethanol? How much is mixed per tank?

Is it used primarily for the drag strip to directly convert NOx to nitrous oxide?

Wrong, Thermal NOX control negatively impacts plant heat rate by reducing the flame temperatures and upsetting the stoichiometry of the fire. NOX emmited from cusbustion sources desiel engines and utility boilers is formed thermally by cumbustion at very high temperatures (~3000F). In general all pollution control devices reduce efficiency and increase CO2 output for a corresponding furnace load. Most existing pollutions limits on power plants can be met with modern technologies by at the cost of $$$$ to the customer and the operator and operating efficiency. Eliminating all pollutants (Particulates, NOX, SOX and now Hg) in mutually exclusive with improving efficiency and lowering CO2 in most cases.

Correctly wrong.

Rule of thumb for every 150 deg F drop in combustion temp, the NOx is reduced in half within max and min temp limits - not the reverse as incorrectly perceived by misinformed professors and guest with no combustion/CEMS/tuning/Operation knowledge.

Coal Combustion

Temp Nox

3500 2.0

3350 1.0

3200 0.5

3000 0.3

Above 3750F the Nox goes crazy.

Below 3000 F the Nox is relatively stable.

As the NOx is properly controlled, the Mw output increases up to 35%, the opacity drops from 20 to 2, and sulfur trioxide declines as well. The challenge is to learn how to intentionally obtain and control the above empiracle data with various fuel combinations.
