5) 9. (CH) and 25% ethane (CH) with 140% theoretical air to supply steam to a generating A natural gas fired boiler burns 13,000 ft/min of gas composed of 75% methane turbine. Assume that the combustion air enters the boiler at 160°F and that combustion products exit the boiler at 300°F. Feedwater for the turbine enters at 1100 psi, 240°F and steam exits at 1100 psi, 1000°F. Under the above conditions/assumptions, determine: a) b) 66666 d) the balanced equation for the combustion process the heat supplied by the combustion process, Btu/lbol fuel (Q/n) the volumetric flow rate of incoming air, cfm the flow rate of water/steam from the boiler, lb/min the dew point temperature of the exhaust gasses, °F
