A gaseous fuel at 220C, 763 mmHg and saturated with water vapor is burned with excess air. Air with 60% RH is supplied at the same temperature and pressure as the fuel. The composition of the fuel shows 9.2% CO2, 0.40% C2H4, 20.9% CO, 15.6% H2, 1.9% CH4 and 52% N2. The stack gas leaves at 4000C and 9.90m H2O and contains 13.16% CO2 and 1.84% CO on a dry basis. Calculate a. Percent excess air b. Complete analysis of the stack gas c. Dew point of the stack gas Solve using a basis of 100 mols stack gas

Question

A gaseous fuel at 220C, 763 mmHg and saturated with water vapor is burned with excess air. Air with 60% RH is supplied at the same temperature and pressure as the fuel. The composition of the fuel shows 9.2% CO2, 0.40% C2H4, 20.9% CO, 15.6% H2, 1.9% CH4 and 52% N2. The stack gas leaves at 4000C and 9.90m H2O and contains 13.16% CO2 and 1.84% CO on a dry basis. Calculate
a. Percent excess air
b. Complete analysis of the stack gas
c. Dew point of the stack gas
