Calculate the percent energy distribution for a steam generator among the following categories: (i) steam, (ii) flue gas losses, (iii) carbon loss in ash (refuse loss), and (iv) miscella- neous heat transfer loss. The steam generator receives 480 short tons per day of coal (a short ton is 2000 lbm). The coal has HHV = 13,000 Btu/lbm. A water flow of 375,000 lbm/hr enters the boiler at 450Â°F, 2500 psia and exits as steam at 1000Â°F and 2400 psia. Combustion air enters at 80Â°F and the flue gases (exhaust) leave at 350Â°F. Ash (refuse) is generated at 45 short tons per day and has an HHV of 800 Btu/lbm. The air/fuel ratio is 20:1. Assume the specific heat of the air and flue gas is 0.24 Btu/lbm-Â°F.
