Sample Questions:

1] An oil fired reheating furnace has an operating temperature of around 1000 °C. Average furnace oil consumption is 330 litres/hour. Flue gas exit temperature after the air preheater is 820 °C. Combustion air is preheated from ambient temperature of 35 °C to 215°C through the air preheater. The other data are as given below

• Specific gravity of oil = 0.92

• Calorific value of oil = 10,200 kcal/kg

• Average O2 percentage in flue gas = 13.5 %

• Theoretical air required = 14 kg of air per kg of oil

• Specific heat of air = 0.23 kcal/kg°C

• Specific heat of flue gas = 0.25 kcal/kg°C

The sensible heat carried away by the exhaust flue gases in kcals/hr and as a percentage of the energy input.

Solution:

• Fuel input = (330 litres/hr x 0.92 kg/litre) = 303.6 kg/hr

• Energy Input = (303.6 kg oil/hr x 10,200 kcals/kg oil) = 30,96,720 kcal/hr

• Excess air = [O2 x 100/(21-O2)] = (13.5 x 100)/(21 - 13.5) = 180 %

• Theoretical air required = 14 kg of air/kg of oil

• Actual mass of air required = 14 x (1 + 180 /100) = 39.2 kg air/kg of oil

• Mass of flue gas (m) = (39.2 + 1) = 40.2 kg flue gas/kg oil

• Specific heat of flue gas (Cp) = 0.25 kcal/kg.oC

• Sensible heat loss in the flue gas = (m x Cp x ΔT)flue gas = (40.2 x 0.25 x (820-35))  Sensible heat loss in the flue gas= 7889.3 kcal/kg of oil

• Sensible heat loss in the flue gas= (7889.3 kcal/kg of oil x 303.6 kg oil/hr)

• Sensible heat loss in the flue gas = 2395176.3 kcal/hr

• Sensible heat loss in the flue gas as % heat loss to input energy = (2395176.3 / 30,96,720) x 100 = 77.35 %
