analyses. The calculated flue gas flow is compared with the reference flue gas flow calculated from the elemental composition. It is shown that, for a wide range of coal and biomass compositions, the above formula performs very well. For light fuel oil the formula is: V God = 1.76435 + 0.20060 H (N) (m 3/kg) and for natural gas: V God

Flue Gas Temperature and Heat in the Flue Gas Flow (Btu

Mar 05, 2019 · The equation assumes that the molar mass of the flue gas and the outside air are equal and that the and heat losses = … Flue Gas Dilution the calculation is: Flow rate in l/sec = 4.44 x rated input of boiler in kW. The volume flow rate provided by the fan will depend on the static pressure imposed by the size and length of flue …

Fuels - Combustion Air and Flue Gases

Oct 01, 2019 · In the actual production of a thermal power plant, flue gas flow is proportional to the load. In this section, a study was presented on the influence of the flue gas flow rate on the NDWCT performance with DFGVs. In practical engineering applications, some power plants will discharge flue gas of two boilers into one cooling tower simultaneously.

HJ 562-2010 PDF. - Chinese Standard

This is because the flue gas velocity of x = 0.1 m, which is near the entrance to the convection chamber, is less than that of x = 1.0 m, leading to a smaller heat transfer coefficient and thus a lower flue gas temperature. The flue gas of upward flow carries out heat exchange with the tubes, and the flue gas temperature field also gradually becomes uniform.
