Superheated steam at 40 bar and 350C is produced from liquid water at 40 bar and 50C 9.2 in a methane-fired boiler. To ensure complete combustion of the methane, 10% excess air is provided. Both methane and combustion air enter the boiler at 25C. Determine the outlet temperature of the flue gas from the boiler, if 19.85 kg/min of superheated steam is produced from the combustion of 1.4 kg/min of methane. Assume the boiler is perfectly insulated Ammoniac thorized throuch the reaction of pritrocenith budron Therontaro
