Flue-gas stack - Wikiped
2019-8-6·A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler
Validated methods for flue gas flow rate calculation wit
2012-2-9·However, it is noted that the flue gas volume per unit of supplied energy, S (m3/MJ), is essentially invariant for a given fuel type and this is a better basis for calculation when compared with the flue gas volume per unit mass. The flue gas volume is derived from the
Flue Gas Recirculation and Excess Air
Flue gas recirculation refers to the admission of flue gases from the boiler exit back into the burner region in order to lower the combustion temperature, as shown in Fig. 4.6, which in turn lowers NOx. See Table 4.2 for the effect of FGR on combustion temperature.

The Benefits of Overfire Air and Flue Gas Recirculatio
Overfire air and flue gas recirculation (OAFGR) systems can offer significant benefits to a stoker-fired boiler system, ranging from more efficiency to fewer emissions. Overfire Air and Flue Gas Recirculation Explained. In this configuration, flue gas is taken from downstream of the boiler and combined with combustion air from a draft fan.
