Coal creates required heat energy by combustion in the furnace. Air is supplied to the furnace to accelerate the combustion rate of the coal and to continue the flow of flue gases inside the heating system. Water is required in a thermal power plant inside a boiler to produce steam. This steam drives the turbine.

Boiler slag is produced in coal-fired power plants that use wet-bottom boilers. It forms from melted minerals left over from coal combustion. This molten ash is quenched with water to form a solid, black, glassy waste product, called slag. Boiler slag is commonly re-purposed as a useful combustion byproduct.

The pulverized coal is then input to a boiler, where combustion occurs and the coal provides heat to the power plant. This heat is transferred to pipes containing high pressured water, which boils to steam. The steam then travels through a turbine, causing it to rotate extremely fast which in turn spins a generator, producing electricity.

Coal for Power Plants. The coal fired power plant converts energy in coal to electricity. The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant.

In a nutshell, coal-fired electricity generation is achieved through quite a complex process: Black or brown coal is pulverised into a powder that's burned in a boiler known as a furnace. The heat generated from this turns water fed into the power station into steam which passes through turbines at high pressure.

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.

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.
