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.
What is the role of gases like CO2, N2O and CH4 in Earth's atmosphere?
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
