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