The diagram above illustrates the process of using coal to generate thermal power.
Overall, there are seven steps through which this electricity is generated, starting from the pulverisation of coal, and ending the electricity travelling to power lines to be used.
The first step is to transfer the coal from where it is stored into a pulverising machine through a conveyor belt. The crushed up coal is now sent into the furnace, where it is subjected to combustion. The heat produced by this boils the water that is present in the pipes in this chamber, and converts it into high pressure and high temperature steam. This steam is directed towards a turbine, which makes it rotate. Meanwhile the water is cooled in the cooler to be reused. The spinning turbine is connected to an electric generator, which uses the mechanical energy of the turbine and converts it into electrical energy. After this, the energy is sent to a transformer to step up the voltage. Electricity is now finally sent to power lines.
