A coal-fired power station or coal power plant is a thermal power station that burns coal to generate electricity. A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin ...

Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills. However if ...

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) 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 ...

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.

Boilers are used to burn coal. But coal is need to be processed before it can be used in power plant as raw coal from coal mine are not suitable as fuel. So coal handling or coal pulverisation system is used in thermal power plant. Process of coal handling: Coal generally comes in power plant in two types of wagon. They are: 1) BOB RM
