Pulverised Coal Combustion with higher efficiency ...

Pulverised coal power plants account for about 97% of the world's coal-fired capacity (IEA 2008, p. 225). The average net efficiency (energy produced minus energy used within the plant) is around 35%, which means that 35% of the energy in one unit of coal is transferred into electricity. Pulverised coal power plants can have a size of up to 1000 MW and are commercially available worldwide.
