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
and the weight of flue gas per pound of coal burned will be .80 × 23.42 = 18.74 pounds. The heat lost in the flue gases per pound of coal burned will be from formula and the value 18.74 just determined. Loss = .24 × 18.74 × (500 - 60) = 1979 B. t. u. The percentage of heat lost in the flue gases …
The flue gas in PF boilers contains approximately 30-40 g/m 3 n of fly ash, which may cause wear of the high-dust SCR catalyst. It is obvious that the deterioration of the catalyst layer reduces its efficiency.
1) Combustion of a fuel gas creates a flue gas with higher density than the fuel gas and the combustion air. Check stoichiometric combustion . 2) Volume at standard pressure
