7. Find the heat carried away by the flue gas at atmospheric pressure, if the composition of its components in volume percent is known, the total volume of gas, the flue gas temperature at the outlet of the furnace t1 and the ambient temperature t2, molar heat capacities (J / (mol * K) of the components flue gas within the specified temperatures are equal to:
СP,CO2=44.44 9.04*10-3T – 8.53*105T-2
СP,CO=28.41 4.10*10-3T – 0.46*105T-2
СP,O2=31.46 3.39*10-3T – 3.77*105T-2
СP,N2=27.87 4.27*10-3T.
Take the number of your option from the table. 1
