hot water boiler coal-fired unit flexibility

Boiler Systems | ERK Energy Systems

ERK has designed coal-fired boiler systems for more than 70 years. We therefore have unique experience with the various coal types available. ERK is able to deal well with new challenges by combining decades of design expertise with innovation. Maximising the efficiency of coal-fired boilers is one aspect to lower its impact on the environment.

Coal fired power plant provide by ZG Boiler which produce electricity by burning coal in the pipe of a coal fired boiler to heat water to produce steam. The steam flows into a turbine at tremendous pressure which spins a generator to produce electricity. The steam is cooled condensed back into water and returned to the boiler to start the coal fired power plant process.

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).
