The installation of a number of induced-draft (ID) fans ensure efficient and reliable operation at South Africa's new large-scale coal-fired power plants, Medupi and Kusile. Ageing infrastructure and a lack of new power stations led to a steady reduction in reserve capacity in the South African electrical power grid, Continue reading Efficiency and environmental protection in coal-fired
Diagram of a typical coal-fired thermal power station. The disposal of ash from a large capacity power station is of same importance as ash is produced in large quantities. Ash handling is a major problem. yes effieceincy of plant are 45-45% but that is thermal efficiency i.e how much coal energy is converted into the electric power.
The rotary electrical generator is very efficient by comparison.The conversion efficiency of a large machine can be as high as 98% or 99%. Transmission of the electrical energy over the distribution grid between the power station and the consumer results in a distribution loss of 10% mainly due to the resistance of the electrical cables.
