Flue gas - Wikipedia

Mar 03, 2008 · The production of carbon monoxide (CO) in the flue gases should be kept below 100-ppm air-free, even though the allowable limit in the stack is 400-ppm air-free. Any time CO is rising and unstable at any level, from 1 ppm to 400 ppm during the combustion process, the burner should be shut down and/or immediately tested and repaired.

1.4 Natural Gas Combustion - US EPA

boilers, nearly all of the fuel carbon (99.9 percent) in natural gas is converted to CO2 during the combustion process. This conversion is relatively independent of boiler or combustor type. Fuel carbon not converted to CO2 results in CH4, CO, and/or VOC emissions and is due to incomplete combustion.

EMISSION FACTOR DOCUMENTATION FOR AP42 SECTION

2.3.2 Carbon Monoxide Emissions The rate of CO emissions from gas-fired combustion equipment depends on the efficiency of the final burnout of this last remaining product of incomplete combustion. Carbon monoxide burnout is strongly kinetically controlled. If final burnout is not achieved quickly at high temperatures, a long residence time in

Do boilers emit carbon monoxide? | Viessmann

Carbon monoxide is produced when your appliance isnt burning its fuel correctly. It occurs when there isnt enough oxygen for the gas to burn completely, resulting in carbon monoxide being formed as a waste product. Boilers can produce carbon monoxide naturally, but

are comparable to emission levels from small stokers. In most boilers, regardless of firing configuration, lower excess combustion air results in lower NOx emissions. However, lowering the amount of excess air in a lignite-fired boiler can also affect the potential for ash fouling. Carbon Monoxide Emissions14-

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived

Coal Fired Boiler Emissions Test - EPA

Jun 15, 1994 · Several factors affect the detection and analysis of an analyte in the stack gas matrix. One is the composition of the stack gas. The major spectral interferants in the coal-fired boiler effluent are water and CO2. At CO2 concentrations of about 10 percent and higher, weak absorbance bands that are normally not visible begin to emerge.
