What are the different kinds of pumps used at power plants? Many different kinds of pumps are used in power plants to fulfill a wide range of applications. Boiler feed pumps are crucial for the operation of power plants. These pumps are typically multistage and deliver feedwater to boilers. An example of a multistage boiler feed pump can be seen in Image 1. Feedwater is then turned into steam

A steam generator or a boiler is that part of a steam power plant in which steam is generated to produce electrical power and/or to get used in an industrial process. A steam generator comprises two important parts, i.e., a furnace, where a fuel is burnt to generate heat, and a proper boiler, where this generated heat is used to convert water
Thus, a thermal power station may sometimes called as a Steam Power Station. After the steam passes through the steam turbine, it is condensed in a condenser and again fed back into the boiler to become steam. This is known as ranking cycle. This article explains how electricity is generated in thermal power plants.
