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 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 supplied is at 27 oC, 765 torrs with 80% RH. Calculate: a. % C and % VCM lost in the refuse b. % excess O2 c. m3 air/kg coal d. Orsat analysis of the stack gas

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 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 supplied is at 27 oC, 765 torrs with 80% RH. Calculate:
a. % C and % VCM lost in the refuse
b. % excess O2
c. m3 air/kg coal
d. Orsat analysis of the stack gas
