Increasing efficiency of pulverised coal-fired power ...

2021-4-26  Many factors impact unit efficiency, including design and operating parameters and coal quality. The current global average is 37.5 % (LHV, net), whereas state-of-the-art plants achieve efficiencies of over 47%. This means that around 2 GtCO2/y emissions could be saved if the gap between the average and the state-of-the-art power plant was closed.

A review of efficiency penalty in a coal-fired power plant ...

The ratio of efficiency penalty caused by CO2 capture to the total efficiency penalty was about two thirds. It appears that while the types of power plant and coal had little influence on efficiency penalty, the CO2 capture technology was critically important. By reducing the regeneration energy of the CO2 scrubbing solvent by 1 GJ/t-CO2, an ...
