Compare the emission factor based on heat generation for CH2OH, C4H10 and coal with high rank degree. LHV CH2OH= 19.915 kJ/kg; LHV C4H10 = 45.725 kJ/kg; LHV coal = 394 kJ/mol.
A fuel used in a boiler contains 86.1% carbon, 11% hydrogen, 2.6% oxygen and 1% sulfur. There are 40% excess air supplies to the furnace and the fuel rate is 400 kg/HR. Calculate the mass of air and the heat energy transfer to the air hour if enters the air heater at 18 Deg c and leaves at 130 Deg c
When a hydrocarbon fuel is burned, almost all of the carbon in the fuel burns completely to form CO2 (carbon dioxide), which is the principal gas causing the greenhouse effect and thus global climate change.
