A burner is fired with coal analyzing 8.6% ash, 13.8% VCM, 3% Moisture, 1.2% S, negligible N and HHV of 13700 BTU/lb. The dry refuse removed analyzes 5% VCM, 27% FC and 68% ash. 60% excess air is supplied at 32O C, 758 mmHg with 85% RH. 90% of the C gasified burns to CO2 , the rest to CO. The molar ratio of H2 to CO is 2:9. % C lost in the refuse is 4.58%. Calculate: Type of refuse m3 air / kg coal Orsat analysis of the stack gas m3 stack gas / kg coal
