100 moles of ethane (C2H6) are burned with 50% excess air. The percentage conversion of the ethane is 90%; of the ethane burned, 25% reacts to form CO and the balance reacts to form CO2. Calculate the molar composition of the stack gas on a dry basis and the mole ratio of water to dry stack gas.

Methane at 25°C is burned in a boiler furnace with 10.0% excess air. The air enters the burner at a temperature of 100°C. Ninety percent of the methane fed is consumed; the product gas is analyzed and found to contain 10.0 mol CO2 per 1 mol of CO. The exhaust gases exit the furnace at 400°C. Calculate the rate of heat transferred from the furnace, given that a molar flow rate of 100 mol/s CH4 is fed to the furnace.

A fired heater uses natural gas as fuel which is burned with 25% excess air. 90% of the fuel burns to give CO2, 4% burns to give CO, and the rest is unburned. (a) Calculate the molar composition of the feed (fuel + air). (b) Evaluate the composition of the flue gases on dry basis. Hints: Air composition may be assumed as 21% oxygen and 79% nitrogen on molar basis.. Natural gas may be assumed as 100% methane

Himmelblau: Toluene, C7H8, is burned with 30% excess air. A bad burner cause 15% of the carbon to form soot (pure C) deposited on the walls of the furnace, what is the Orsat analysis of the gases leaving the furnace? Ans: 9.1% CO2; 8.9% O2; 82% N2 Please include diagrams, calculus, and important notes. Thanks!

100 mol n-Hexane (C6H14) is burned with excess air. An analysis of the product gas yields the following dry-basis molar composition: 6.9% CO2, 2.1% CO, 0.265% C6H14 (+ O2 and N2). The stack gas emerges at 760 mm Hg. Calculate the percentage conversion of hexane, the percentage excess air fed to the burner, and the dew point of the stack gas, taking water to be the only condensable species.
