2016-9-26·value. The increased gas flow, however, does not have an appreciable effect on the design and operation of boiler components downstream of the burner. The added volume of non-combustible (inert) gas in LFG is equivalent to the inert gas entering a boiler when about six percent of the flue gas is recirculated to the boiler.

Flue gas recirculation technology can be classified into two types; external or induced. External flue gas recirculation utilizes an external fan to recirculate the flue gases back into the flame. External piping routes the exhaust gases from the stack to the burner. A valve controls the recirculation rate, based on boiler
