boiler smoke waste heat saving

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C ( Shen and Cheng, 2004 ).

The exhaust heat loss is the heat loss caused by a part of the heat that is taken away by the smoke of the boiler. Its size is related to the amount of smoke, the smoke exhaust and the reference temperature and the sensible heat of the water vapor in the flue gas. q2 can be used as a simplified calculation formula: q2 = (3.55αpy +0.44) (tpy-t0) / 100
