COMBUSTION CALCULATIONS
This calculating method for heat losses in steam generating
units provides quick answers of good accuracy based on either
an ultimate or a proximate fuel analysis.
Because the weight of air required for combustion of a unit
weight of any fuel is more nearly proportional to the unit heat
value than to the unit weight of that fuel, the weights of air, dry
gas, moisture, wet gas, etc., are expressed in pounds per million
Btu fired.
