Thermal power plants convert heat into power in the form of electricity. The heat is generated from a diverse range of sources, including coal, natural gas, uranium, solar energy, and geothermal energy. The heat rate (HR, kJ/kWh) of a power plant is the amount of heat input required (kJ/h) to produce one unit of electricity (kW) (see Equation 1 ...

The Ministry of Power issued a policy on biomass utilisation for power generation through co-firing in coal-based power plants.

The coal mill is one of the important auxiliary engines in the coal-fired power station. Its operation status is directly related to the safe and steady operation of the units. In this paper, a model-based deep learning algorithm for fault diagnosis is proposed to effectively detect the operation state of coal mills. Based on the system mechanism model of coal mills, massive fault data are ...

The ball mill has been the industry's workhorse for over a century and despite its estimated meagre four per cent efficiency, little has changed over the years other than increases in the wear resistance of mill internals and the scale of the equipment. ... Table 1: grinding technology comparison – power use (mill + auxiliaries) Plant 1 ...
