The heat to dry the coal is recovered from the boiler exhaust gas stream. Pulverized coal from the pulverizer is blown into the boiler with the primary air stream. The coal at this stage is finely ground and very dry, both of these characteristics aid combustion. Combustion occurs and heat is generated (this plant is a ‘ thermal power plant ')

However, traditional coal-fired thermal power plants are relatively inefficient at converting thermal energy to electrical energy, because they use only the steam produced in order to generate the power to rotate the plant's turbines. Coal also has a harmful effect on global warming because it releases more CO2 emissions than other fossil fuels
Pulverized coal power plants are broken down into four categories, with operating temperatures and pressures as a function of the steam temperature and pressure: •. Subcritical pulverized coal (SubCPC) plants, below the critical point of water (540°C and 170–220 bar), have an operating efficiency <38%. •
