This raises the possibility that power plant developers will continue to follow the pattern of the 1990s and rely heavily on natural gas plants to meet the need for new power generation.! With current technology, coal-fired power plants using carbon capture equipment are an expensive source of electricity in a carbon control case.
Coal Mills in Thermal Power Plant
Impact mill: These are high-speed impact machines that use beater wheels to crush the coal. Ball Tube Mills. Tube mills: The tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. If the length of the cylinder is greater than the diameter of the cylinder, it is called a tube mill.
