Question

10 percent CO2, 1.2 percent CO, and 8.7 percent O2 are found in the stack gas produced by coal burning. 870°F. The air in the boiler is saturated with water vapor and enters at a temperature of 70 degrees Fahrenheit.Assume a pressure of 745 millimeters of mercury.

a. You must understand the ratio in order to complete your boiler report.the coal's net H to carbon ratio, and the coal's final analysis InitialThe coal has a carbon content of 73%, 5.2 percent moisture, and 10% ash, according to the statistics.

Assume that nitrogen and sulfur levels ARE NEGLIBLE

b. how much air is required in ft3/lb of coal?
c. If the boiler burns 50 tons of coal per day, how many ft3 of stack gas is produced?
Assume a base of 100 lbmols of stack gas.
