Two kmol of ethane (C2H6) is burned with an unknown amount of air during a combustion process. An analysis of the combustion products reveals that the combustion is complete, and there are 4 kmol of free O2 in the products. Determine (a) the air–fuel ratio and (b) the percentage of theoretical air used during this process (c) The equivalent ratio

A natural gas mixture of methane (CH4) and ethane (C2H6) are used for the fuel source for generation of steam in a refinery plant.In this process,The gas stream mixture 1000kg/min having 70wt% CH4 and 30wt% C2H6 is burned with 100% excess air.Gas analysis shows that the CH4 and 85% C2H6 are completely burned into carbon dioxide , while 10% C2H6 is partially burned into carbon monoxide and the remaining C2H6 is unreacted. Assume the air stream feed to the furnace...

Problem 2. A novel gaseous hydrocarbon fuel CxHy is proposed for use in spark-ignition engines. A sample analysis of this fuel revealed that its molecular weight is 140 kg/kmol and its molar H/C ratio is 2. In order to evaluate some of its properties, the fuel was burned with stoichiometric atmospheric air in a constant pressure, steady-flow reactor. The fuel and air entered the reactor at 25 C, and the products of complete combustion were cooled to 25 C. At...

A fuel gas containing 75.0 mole% methane and the balance ethane is burned completely with 35.0% excess air. The stack gas leaves the furnace at 800.0°C and is cooled to 350.0°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. Take as a basis 100.0 mol of the fuel gas fed to the furnace. The amounts of each of the...
