Introduction. Steam cycles have been used for electric power generation from coal since the early 1900's. These first coalfired power units featured outputs in the range 110 MW and the steam generator already included an economizer, an evaporator, and a superheater (Harvey et al., 2020).According to the same reference, the first steam cycle had an efficiency of only % while those ...

Coal was the thirdlargest energy source for electricity generation in 2022—about 18%. Nearly all coalfired power plants use steam turbines. A few coalfired power plants convert coal to a gas for use in a gas turbine to generate electricity. Petroleum was the source of less than 1% of electricity generation in 2022.
