    Generic Boiler Output Formula? - Boiler and Pressure

    Jan 30, 2006 · Since combustion equation has 3 moles of gas on both LHS & RHS, for exhaust gas can use (NG + combustion air) volume. Only need to correct for temperature per gas law. Best to use the actual exhaust T, but if not available, use 400 o F. The boiler mfr. recommends the stack ID, so from volumetric flow, you get the exhaust velocity.

    Flue-gas flow-rate induced by the draft. As a "first guess" approximation, the following equation can be used to estimate the flue-gas flow-rate induced by the draft of a flue-gas stack. The equation assumes that the molar mass of the flue gas and the outside air are equal and that the frictional resistance and heat losses are negligible:.
