Mean specific heat of flue gas - Energy engineering

Apr 16, 2004 · I need to calculate the mean specific heat capacity of a flue gas.Problem is, the flue gas is a product of oxy-fuel combustion with CO2 as a major component and rest being H20. The temperature of the combustion system varies from 1000 to 1400°c and pressure from atmospheric to 16 bar. Can you suggest me how I can calculate it.

Aug 02, 2007 · for every 15 lbs of fuel, you need 1 lb air. The lbs burned will be lbs carcus-lb ash + lbs fuel. Take that number multiply by 16 to get total lbs of flue gas. The lowest temperature you want to cool the flue gas is about 250 to 300 F, any lower and you will condense out all kinds of acids. So Q = (900F - 300F) * lbs * heat Capcity for N2 of .24.
