Example 16 To avoid the possibility of explosion in a vessel containing gas having the composition of 40% N2, 45% O2, and 15% CH4, the recommendation is to dilute the gas mixture by adding an equal amount of pure N2. What is the final mole fraction of each gaś? Solution

Given the Ultimate analysis of Alabama coal: Sulfur = 2.12% Hydrogen Ash = 6.40% Carbon = 77.76% Nitrogen = 2.92% Oxygen = 6.52% Moisture = 3.62% Using Ash and Moisture-free analysis, calculate the Actual A/F ratio at 15% excess air. = 4.28%

Please answer the question with the steps... Thank you

A hydrocarbon fuel is burned with excess air. The Orsat analysis of the exhaust gas is 10.2 % CO2, 1.0 % CO, 8.4 % O2 and 80.4 % N2. What is the atomic ratio H to C in the fuel and what is the % excess air used in the combustion?
