Bulldozers for Coal fired Thermal Power Plants Generating Electricity.
Thermal Power PlantsAlmost two thirds of electricity requirement of the world is fulfilled by thermal power plants (or thermal power stations). In these power stations, steam is produced by burning some fossil fuel (e.g. coal) and then used to run a steam turbine. As the majority of thermal power plants use coal as their primary fuel, this article is focused on a coal fired thermal power plant.
Heavy earthmoving machinery such as Bulldozer Excavator plays a very important role in Thermal Power Plants. Huge amounts of coal are pushed by bulldozers into the turbine to start the process.
Thermal power generation plant or thermal power station is the most conventional source of electric power.Thermal Power Plant consists of a set of steps in series for producing electricity. Bulldozers are used for stacking and pushing of coal to the hot furnaces such that the coal is burnt into the furnace of steam boiler and high-pressure steam is produced.
This steam is then passed through the super heater, where it is further heated up.This super-heated steam is then entered into a turbine at high speed.
In turbine this steam force rotates the turbine blades that means here in the turbine the stored potential energy of the high-pressure steam is converted into mechanical energy.
This process converts the chemical energy of the coal into electrical energy and is achieved by raising the steam in the boilers, expanding it through the turbine and coupling the turbines to the generators which converts mechanical energy into electrical energy.
