Study Notes

A Stacker is responsible for storing and reclaiming coal in a thermal power plant.
The primary purpose of a Boiler (Steam Generator) is to produce steam by burning fuel, which is then used to drive a turbine to generate electricity.
Pulverizers are used to crush coal into a fine powder, increasing its surface area to facilitate efficient burning in the boiler.
Deaerators remove dissolved oxygen and other gases from the feedwater to prevent corrosion and improve the overall efficiency of the boiler.
The purpose of an economizer is to preheat the feedwater before it enters the boiler, increasing the overall efficiency of the boiler system by reducing the amount of heat energy required to produce steam.
A Silo is used to store coal, limestone, or other bulk materials in a thermal power plant.
An electrostatic precipitator (ESP) is used to remove particulate matter, such as ash and dust, from the flue gas before it is released into the atmosphere.
In a Rankine cycle, the primary function of the condenser is to cool the steam turbine exhaust, condensing it back into liquid water, which is then reused in the boiler.
The primary purpose of a cooling tower is to dissipate the heat generated by the condenser to the atmosphere, allowing the cooled water to be reused in the power plant.
The primary function of a hydropower plant is to generate electricity by harnessing the energy of moving water, using the kinetic energy of the water to drive a turbine.
