In a thermal power plant, a boiler generates steam, and then the steam is sent to a steam turbine, and the rotation of the steam turbine drives a generator to generate electricity. The exhaust of the turbine enters a cold end device called a condenser, condensed water is sent to a feed pump by a condensate pump and then enters a boiler. This is a cycle.
