A syngas fuel consists of these following volumetric composition: 75% methane and 25% butane. The syngas at 100 kg/hour and 25 C is mixed with 20% excess air at 30 C. Due to incomplete combustion mechanics, 10%v of the syngas carbon is partially oxidized and forms carbon monoxide. If the products of combustion are at 600K, obtain the combustion heat transfer rate from the system.
