Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived … WebA lower furnace exit temperature also means a lower flue gas temperature at the inlet of the superheater and may thus prevent the plant from reaching the nominal live-steam temperature. This problem can partly be offset by using FGR to increase the flue gas flow and reduce furnace heat transfer (so-called tempering) when firing dry fuels, and ...
