In thermal power plant, pulverization of coal is carried out by coal mill. Raw coal is moved from the storage to the mill by conveyor mechanism. The type of coal mill envisaged for our model is bowl mill which is shown in Fig.1. Raw coal is introduced near the centre of the grinding table through the coal feed pipe.
A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.

Stage 1. The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2. The …
Instrumentation and control is an integral part of a coal-fired power station. A modern, advanced I&C system plays a major role in the profitable operation of a plant by …
Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
Steam turbine plants have been in use for over a hundred years, and have reached supercritical conditions with percentage efficiencies in the upper 40s, LHV (lower heating value) basis, at favourable locations. Coal-fired power plants can also be based on combined gas and steam cycles, which use gas turbines as well as steam turbines. This …
As mentioned in Section 1, the change of coal in a thermal power plant typically happens over a period of several hours (referred to as coal transition) and there is an irregular time lag between the coal change at the bunker level and that at the mill or boiler level (Tuttle et al., 2020). Therefore, real-time detection of change of coal in an ...

Power Generation from Coal Measuring and Reporting Efficiency Performance and CO 2 Emissions Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climate-damaging carbon dioxide.
After burning of coal, 40 % of total coal consumption is converted into ash which need to be properly disposed-off from the thermal power plant. Types of Ash Generated in Thermal Power Plant. Bottom Ash – Ash generated below furnace of the thermal power plant is called the bottom ash. The value of bottom ash generated is …
