Abstract: In recent years, the load following capability of thermal power plants has been actively researched, as power system interconnection unavoidably brings about complicated load variations. The key to improving the load following capability is the control of the fuel supply to the burner, which is provided by the coal mill.
Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coalbased power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38 %, with stateoftheart fossil fuel ...

Abstract. In modern thermal power plants coal grinding mills are an important and very frequent subsystem. As time passes the grinders in the mills become depleted and the functionality of these mills decreases. Because of that the mills need to be stopped periodically, every 1500 hours, so they can be checked and, if necessary, repaired. During
