Propane (C,H,) is used in a combustion process with atmospheric air. A gas analyzer is used to analyze the exhaust products, the digital screen of this analyzer showed that, the volumetric percentages of the dry products of combustion are as follows: 44.5% O; 4 8.5 % CO, 42.5% CO Write down the associated combustion equations and then: Calculate: a) The percentage of theoretical air b) The percent of excess air, c) The air-fuel ratio Propane (C,H,) is used in a combustion process with atmospheric air.
