coal power plant efficiency

Conventional coal-based power generation has improved significantly in recent years. Efficiencies of around 45%, and even higher at particularly favourable locations, are nowadays achievable. Future developments will be aiming at 55%. New technologies make even greater increases possible.

Efficiency ratings for supercritical coal plants range from 37% to 40%. [1] In ultra-supercritical units, pressures are at 4640 pounds per square inch and temperatures at 1112-1130 degrees Fahrenheit (600-610 degrees Celsius).

Ultra-supercritical coal-fired power plants (USC) with carbon capture systems (CCS) are a potential way to ensure clean power generation and support renewable energy integration. This paper has analysed the energy consumption and exergy flow in USC and CCS under load-cycling operation conditions.

Virtually all coal plants in current operation employ pulverized coal combustion technology, which involves grinding coal into talcum-powder fineness and then burning it to heat water into high-pressure steam to drive an electrical generator.

In 2012, coal was used to fuel approximately 38% of power generation in the United States, as shown in Figure 1. Coal has been the fuel of choice for many decades because of its wide availability, and the relatively low cost of producing electricity in large, coal-burning power plants.

The average coal-fired power plant in the United States operates near 33% efficiency. The Transformative Power Systems Research Program aims to increase the efficiency of existing plants by 5% by 2023 and for new plants by 2027.

Reported efficiencies of natural gas combined-cycle power plants are between 45 and 57% and efficiencies of coal-fired power stations are in average 33% worldwide, 38.6% in China and 41.6% in Japan (POWER, 2017), while state of the art coal plants are reported to reach efficiencies of 40–50% (Storm, 2020;
