features of major types of coal used for power generation are listed in Table 1. Pulverised coal (PC) is the fuel used in about 97% of the world’s coal-fired capacity (IEA, 2008). In a pulverised coal-fired power plant, coal is milled and burned with air in tall boilers that provide for complete burnout and efficient heat transfer.

Supercritical coal plant Energy Education

Supercritical coal plants are a type of coal-fired power plant used in more modern designs. They differ from traditional coal power plants because the water running through it works as a supercritical fluid, meaning it is neither a liquid or a gas.This occurs when water reaches its critical point under high pressures and temperatures, specifically at 22 MPa and 374 o C.
