PROBLEM: The following fuel with each corresponding flow rate was burned individually inside the furnace with 150% theoretical air. No. Fuel Type Chemical Formula 1 Methane 2 Ethane 3 Propane 4 Butane 5 Pentane 6 Octane CH 7 Dodecane CH CH CH GH CH CH 8 Ethylene CH 9 Propylene CH 10 Acetylene 11 Ethanol CHO 12 Methanol CH,OH Flow Rate 100 kg/hr 120 kg/hr 140 kg/hr 160 kg/hr 180 kg/hr 200 kg/hr 220 kg/hr 240 kg/hr 260 kg/hr 280 kg/hr 300 kg/hr 320 kg/hr Determine: a. The amount of air used during combustion, in m/hr, when air is supplied at 27C and 1 bar. b. The minimum duct diameter, in mm, used for supplying combustion air to the furnace if the allowable velocity of air across the duct is 12 m/s. c. The amount of flue gas, in m/hr, leaving the furnace at 127C and 1 bar. d. The minimum stack diameter, in mm, for flue gas disposal if the allowable velocity of flue gas across the stack is 10 m/s.
