a chemical engineer working for a power plant industry. One of her operators told her that the valve, operating automatically, that allows air to enter the furnace is broken. So they have to manually turn the valve for air to enter. If the analysis of the products of combustion measured from the stack contains 14.26% CO2, 0.52% CO. 0.41% H2, 4.32% O2 and 80.49% N2. These gases exit at a temperature of 444°F with a partial pressure for the water as 20 mmHg. The air entering the furnace is at a temperature of 92°F with a partial pressure for the water vapor as 20 mmHg. The coal used in the furnace carries 4.8% moisture, 10% ash and has a low sulfur and nitrogen content fired at 3180 lbs/hr. The barometer is 750 mmHg and combustibles are well burnt out of the refuse. a) How much lbmols of dry stack gas is produced? b) What is the %weight of hydrogen in the coal? c) What is the %weight of oxygen in the coal?
