The outlet temperature of the coal mill is maintained at desired point so that the coal delivered from the mill is completely dry and achieves the desired temperature. Also, in case of high temperature at the mill outlet, cold air is blown in to reduce the risk of fire.
One of the key subsystems in thermal power plants is the coal mill used to pulverize the coal before it gets into the plant furnace. The interior of the mill rotates and the plates located on the inside grind the coal into a small size powder. During that process the plates within the mill slowly get depleted and the productivity of the mill gradually de-creases until it becomes completely dysfunctional (Figure 1).

Thermal energy is the major source of power generation in India. More than 60% of electric power is produced by steam plants in India. India has large deposit of coal (about 170 billion tonnes), 5th largest in world. Indian coals are classified as A-G grade coals. In Steam power plants, the heat of combustion of fossil fuels is utilized by the ...
Many utility systems in the world have power plants operating with fossil fuel. In the thermal power plants maximum requirements of fuel is a coal. The handling of this fuel is a great job. To handle the fuel, i.e., coal, each power station is equipped with a coal handling plant. Maintenance

Jan 10, 2017 The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.

Jun 22, 2015 Since most of the water needs in thermal power plants are for cooling, the amount of water required by the power plant will depend on the type of cooling system used (and not as much on the fuel type). Thus, a Type X plant with dry cooling will certainly require less water than a Type Y plant with cooling towers, for example.
Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100m) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...
Mar 18, 2017 Construction and working of thermal power plant. by - Mayuresh Joshi on - March 18, 2017. Thermal power plant uses steam energy for the generation of the electricity. Fossil fuels like coal, oil, natural gases are burnt in the boiler, a hot flue gases thus generated are used to heat the feed water. A superheated steam is generated.
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.
