AP-42 Section 1.6 Wood Residue Combustion in Boilers

The boiler rule regulates dioxins/furans, mercury, and hydrochloric acid (HCl) directly, with HCl also acting as a proxy for other acid gases (like hydrogen fluoride). To control emissions of these pollutants, EPA sets maximum emissions rates for different kinds of boilers and different fuels.

Flue gas - Wikipedia

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas
