The issues of sensible heat of dry flue gas, sensible heat of water vapor, and latent heat of water vapor
Thread Content
Gentlemasters! How is the sensible heat of the dry flue gas, the sensible heat of water vapor, and the latent heat of water vapor in the flue gas calculated before and after desulfurization? Assuming that all the heat from the flue gas during the desulfurization process is used for water evaporation, heat should be conserved before and after desulfurization, right? Before desulfurization, it is high-temperature flue gas; after desulfurization, it is low-temperature saturated wet flue gas. Could someone expert please give some guidance? Just the general approach is enough, thanks! Moreover, the water vapor in high-temperature flue gas is not saturated water vapor; the latent heat of vaporization values obtained from tables refer to saturated conditions. How should this be understood and calculated?
The moisture in the flue gas after desulfurization is saturated, and the flue gas also contains free water; feel free to contact me if you need help with the calculations. In this calculation, the process flue gas exit temperatures for limestone and lime are different; if only the specific heat of the flue gas is taken into account, the exit temperature will be inaccurate, generally being on the low side
