DryCoke composed of 4% inert solids (ash), 90% carbon, and 6% hydrogenat 40C is burned in a furnace with dry air at 40C. The solid refuseat 200C that leaves the furnace contains 10% carbon and 90% inert,and no hydrogen. The ash does not react. Analysis of the flue gaswhich is 1100C gave 13.9% carbon dioxide, 0.8% carbon monoxide,4.3% oxygen, and 81.0% nitrogen. There is also a third exit streamwhich is a superheated steam at 1100C. Dry coke is combusted withdry air to generate the solid refuse, the flue gas and thesuperheated steam. Calculate the heat transfer to of from theprocess. Use a constant Cp for the inert of 8.5 J/g and assumeeverything at 1atm.
