- What products of combustion are produced with ideal combustion when fuel oil is burned?Write the general energy balance for any combustion process. Is my answer correct?Question No.14: A certain natural gas has following volumetric analysis: 65 percent CH4, 8 percent H2, 18 percent N2, 3 percent O2, and 6 percent CO2. This gas is now burnt completely with the stoichiometric amount of dry air. What is the air-fuel ratio for this combustion process?
- If one mole of air/fuel mixture (rigid diatomic gas) is initially at 20◦C, is compressed and expanded 7-fold as part of the Otto cycle, and 4 kJ of heat is generated by burning the air/fuel mixture, calculate: (i) the temperature after each stage of the Otto cycle; (ii) the heat absorbed/expelled during each stage of the cycle; and (iii) the efficiency of the Otto cycle.Liquid octane is burned completely with 75% excess air. Determine the air-fuel ratio for this combustion process.Question No. 12: Methane CH4 is burned with stoichiometric amount of air during a combustion process. Assuming complete combustion, determine the air-fuel and fuel-air ratios.
- In the complete combustion of an ideal gas, which of the following yields a higher exit temperature in the burner? Assume all products are in the gas phase. 1. Increasing the percent excess air 2. Decreasing the inlet temperature of fuel a.2 only b.1 only c.Both 1 and 2 d. None of the choicesWhen a hydrocarbon fuel is burned, almost all of the carbon in the fuel burns completely to form CO2 (carbon dioxide), which is the principal gas causing the greenhouse effect and thus global climate change.During tests on a turbojet engine an unknown fuel is used. The dry product gases are analysed and found to contain 12.1% CO2, 3.8% O2 and 0.9% CO by volume. What is the average make-up of the fuel? How much water is present in the exhaust? What is the balanced combustion equation? What is the Air to Fuel ratio by mass?
