Fuels - Combustion Air and Flue Gases

The efficiency loss in the flue gas related to. temperature difference in flue gas and supply air ; CO 2 concentration in the flue gas; with oil combustion is indicated below: Example - Oil Combustion and Heat Loss in the Flue Gas. If. the temperature difference between the flue gas leaving a boiler and the ambient supply temperature is 300 o C, and; the carbon dioxide measured in the flue gas is 10% - then, from the …

(PDF) Data analysis of the flue gas emissions in the

Two postcombustion technologies that may be applied to natural gas-fired boilers to reduce NOx emissions are selective noncatalytic reduction (SNCR) and selective catalytic reduction (SCR). The SNCR system injects ammonia (NH3) or urea into combustion flue gases (in a specific temperature zone) to reduce NOx emission.

Combustion Efficiency and Excess Air

Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the …
