In a coal-fired boiler with wet-desulphurization, a portion of the flue gas thermal energy is used for the latent heat process, which leads to temperature reduction and humidity increase. Although it still contains significant heat, flue gas without sulfur cannot be further utilized; as such, in conventional systems, it is directly exhausted.
In a typical coal-fired boiler, coal is burned and the heat is extracted to generate steam. The steam is used to drive a turbine, which in turn, drives an electrical generator. Low pressure steam leaving the turbine is fed to a cooling system which extracts any residual heat and condenses the steam back to water.
