coal processing in a boiler
Boiler Combustion
A boiler utilizing a standard burner with a 4:1 turndown can cycle as frequently as 12 times per hour or 288 times a day because the boiler must begin to cycle at inputs below 25% capacity. With each cycle, pre- and post-purge air flow removes heat from the boiler and sends it

HOW ELECTRICITY IS PRODUCED AT A COAL
Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas. The pulverised coal is transported to the boiler furnace with air where it burns. Boilers, as high as a 35-storey office block, are the rectangular blocks that give power stations their distinctive

Working of Boiler – Explanation, Parts, Working Principle
The boiler is a closed vessel, where the water is stored. Hot gasses are formed by burning fuel in the furnace. These glasses are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.

Pulverized fuel boiler: Coal is pulverized into a fine dust (about 0.1 mm in size), and is fed into the boiler in a stream of air. They are by far the most common boiler types for coal. These boilers can reach efficiencies of over 90% when they are well run. They can be co-fired with wood or other suitable fuels as well.

How a Coal Plant Works Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
