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

The flue gas temperature can be determine in this case by an iterative process of inputting the flue gas mass flows and an assumed flue gas temperature to see if the Total Flue Gas Btu/hr is equal to 21,194.31 Btu/hour, if not you try another assumed temperature.

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
