1. 3000 lb/hr of coal is burned using 20 % excess air at a pressure of 14.7 psia and 70F. The ultimate analysis of coal is: Carbon = 66.1 %, Hydrogen = 6.03 %, Oxygen = 11.91 %, Nitrogen = 1.04 %, Sulflur = 2.4 %, Ash = 12.52 %. Determine: a) Air to fuel ratio by weight, b) wet and dry flue gas analysis, c) capacity required of a fan used to supply combustion air (ft/min), d) Volume of flue gases at 14.7 psia and 200F. e) weight of COformed
