A fuel gas of 73 mol% ethane and the balance propane is burned continuously with 69% excess air to provide energy to a boiler to generate steam. In the combustion process, 86% of the ethane and 75% of the propane are burned. If 22 mol/s of the fuel gas are fed to the combustion chamber at 1 atm and 25 C, the product gases emerge at these same conditions, what is the maximum rate of heat supply to the boiler (positive quantity) in MW (1 MW = 1 megawatt = 106 W)? Assume the H2O produced in the combustion process leaves as liquid water and the rest of the components are in the gas/vapor phase. Show all work, cite all sources, state all assumptions. Report answer in MW with 3 digits of precision in decimal format.

A fuel gas of 73 mol% ethane and the balance propane is burned continuously with 69% excess air to provide energy to a boiler to generate steam. In the combustion process, 86% of the ethane and 75% of the propane are burned. If 22 mol/s of the fuel gas are fed to the combustion chamber at 1 atm and 25
C, the product gases emerge at these same conditions, what is the maximum rate of heat supply to the boiler (positive quantity) in MW (1 MW = 1 megawatt = 106 W)? Assume the H2O produced in the combustion process leaves as liquid water and the rest of the components are in the gas/vapor phase. Show all work, cite all sources, state all assumptions. Report answer in MW with 3 digits of precision in decimal format.
