Answer to Question #126327 in Thermal Power Engineering for Sahil

Question

Propane gas is to be burned in a furnace at the rate of 1000 LPH at STP, using 15% 

excess air. For achieving energy efficient operation, preheated air at 100 C is to be used. 

Assume that the ambient air completely dry and at 1 atm absolute pressure is available at 

10oC. Calculate the energy required for heating the air (in kJ/h) from 10C to 100oC.
