Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coalfired thermal power plants, the raw coal is first pulverized to the shape of flour before it is forcefed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated ...

The combustion system, typically made up of a ring of fuel injectors that inject a steady stream of fuel into combustion chambers where it mixes with the air. The mixture is burned at temperatures of more than 2000 degrees F. The combustion produces a high temperature, high pressure gas stream that enters and expands through the turbine section.

Producing sustainable clean energy is one of the key challenges in modern power generation systems. Coalfired power plants are one of the main sources of electrical energy due to the low cost of coal compared to other fossil fuels. However, one of the major problems of the coalfired power plant is the exhaust emission of fine particulate matter.

These designs are popularly associated with nuclear power plants. However, this association is misleading, as the same kind of cooling towers are often used at large coalfired power plants and some geothermal plants as well. The steam turbine is what necessitates the cooling tower. Conversely, not all nuclear power plants have cooling towers ...

Like any thermal power station, we generate electricity from steam. Our entire process can be simplified into four main steps: Fuel is burned to create heat. By using finely pulverized coal, efficient combustion is assured and high temperatures are achieved. The heat is applied to demineralized water inside the boiler, turning it into steam.

A simplified layout of a thermal power station is shown below. Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage ...

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 second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.
