5. Coal fired in a furnace analyzes 16.6% VCM, 16% ash, 61.4% FC, 6% M, 1.2%N and 1.8%S with a calorific value of 26.75 MJ/kg. Analysis of the Residue shows 44% ash, 8% VCM, 34% FC and 14% H,O. Partial orsat analysis of the stack gas shows 10.77% Co, , 1.62% CO and 0.81% H2. Air supplied is at 27°C, 765 torrs with 80% RH. Calculate: a) %C and %VCM lost in the Residue (19.92, 17.52)
