As a chemical engineer, you are employed in a power plant industry and is assigned in the supervision oF the boiler operation. The boiler uses coal as its Fuel, supplied by a third—party supplier. The stack gas produced upon combustion of the coal analyzes 11.2% C02, 8.7% CO and 8.3% 02 at QBBDF. The air supplied in the boiler is saturated with water vapor and enters at 73°F. Assume a barometric pressure of T58 mmHg. a. To be able to complete your report around the boiler, you need to know the ratio of net H to carbon in the coal, as well as the ultimate analysis of the coal. Initial data From the coal says it contains 76.1% carbon, 6.9% moisture and 8% ash. Assume negligible nitrogen and sulfur content. b. How much excess air is supplied in the boiler? Also, a value is used to control the air entering the boiler, how much air is needed in Ft3flb of coal? c. In one day, the boiler makes use of 56 tons of coal, how many Ft3 of stack gas is produced? Establish basis as 168 lbmols of dry stack gas.
