Regarding the differences in flue gas composition, how is the heat content of the flue gas calculated?
Thread Content
CO2, CnHm, O2, CO, CH4, H2, N2: 0.5-1.5, 3.5-7.3, 0.2-0.3, 0.1-0.3, 85-95, 0.4-0.8, 1.5-5, 4, 0, 0.2, 25, 4, 20, 46.8, 9.2, 0.2, 0.6, 19.7, 1.9, 22.8, 45.6. Dear experts, I currently have three different compositions for the flue gas, and I would like to calculate its heat content. How should I go about doing this? ! ! ! I really can’t!
It is generally calculated using a weighted average; taking the second type of flue gas as an example: carbon dioxide heat capacity * 0.04 + O2 * 0.02 + CO * 0.25 + CH4 * 0.04 + H2 * 0.2 + N2 * 0.468
It can be calculated using the specific enthalpy polynomial of an ideal gas.
Hello, thank you very much for your guidance. I would like to ask: if I want to calculate the heat content of such flue gas components, how should I do that? If there are any parameters that need to be provided, please let me know and I’ll send them to you! Thanks!
