When natural gas (mainly CH4) is burned with 10 percent excess air, in addition to the main gaseous products of CO2 and H2O, other gaseous products result in minor quantities. The Environmental Protection Agency (EPA) lists the following data: Emission Factors (kg/106m3 at SC) SO2 NO2 CO CO2 Large Utility boiler, uncontrolled 9.6 3040 1344 1.9x106 Large Utility boiler, controlled gas recirculation 9.6 1600 1344 1.9x106 Residential furnance 9.6 1500 640 1.9x106 The data are based on 106m3 measured at SC of methane burned.
