Calculate the percent energy distribution in a steam generator that goes into steam, losses to flue gases, refuse and heat losses. The steam generator receives 480 short tons of coal per day. The heating value of coal is 13,000 BtU/lb",. 375,000 Ib,jh of water enters the steam generator at 2500 psia and 450"F and leaves as steam at 2400 psia and 1000"F. Combustion air enters at 80"F and the flue gases leave at 350"F. The refuse, generated at the rate of 45 short tons per day, has an internal energy of 800 BtuIlb". The airfoil ratio by mass is 20:1. Assume that the flue gases have the same variable specific heat as air.
