Overview. The Thermal Power Plant can burn any chemical fuel and provides power. This process is, however, only 80% efficient, meaning you can only obtain 80% of the displayed energy of the fuel. For example Coal has a displayed value of 2.7 MJ, but the power plant will only extract 2.16 MJ (80%) of the energy.

The degree of fineness should be held to the least possible which will still maintain satisfactory furnace and combustible loss conditions. Efficient classification is important to restrict passage of particles larger than U.S. Sieve No. 50 to less than 1 per cent of the coal fired as these particles will not be fully burned, thus increasing the loss due to combustible in the refuse.
