calculate steam fuel ratio fired boiler – Fire Tube . 2017-1-24 · For natural gas fired boilers the lowest recommended flue gas temperature coming out of an . Boiler efficiency expresses as ratio of heat content of steam generated per hour.
1.4 Natural Gas Combustion - US EPA. 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
