Coal fired in a furnace analyzes 16.6% VCM, 16% ash, 61.4% FC, 6% M, 1.1% N and 1.8% S with a heating value of 26.75 MJ/kg. Analysis of the refuse shows 44% ash, 8% VCM, 34% FC and 14% H2O. Partial Orsat analysis of the stack gas shows 10.77% CO2, 1.62% CO and 0.81% H2. Air is supplied at 27°C, 765 mmHg with 80% RH. Calculate: (a) % VCM lost in the refuse, (b) % C lost in the refuse, (c) % excess air, (d) Orsat analysis of stack gas, and (e) m3 stack gas/ kg coal.
