furnace is to be designed for a heat duty of 11111.1 BTU/s. If the overall efficiency is 75%. The furnace is fired air amount is 17 times amount of fuel and an oil fuel of (NHV =1700 BTU/lb). The tube are arranged in two rows and are of 5 in O.D., 12.19 m length and 2 × O.D. Spacing, heat rate of 35000 BTU/hr of projected area is recommended. Calculate: 1) Heat absorbed in the Radiation section. 2) Number of tubes in radiant section, and 3) Heat absorbed in the Convection section. Given: Furnace Losses -5%; Stack Losses-12; 1ft-0.3048
