A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.
What happens in the boiler of a power station?
Boiler: In the boiler, heat from the furnace flows around pipes full of cold water. The heat boils the water and turns it into steam. … Boiling hot water from the steam turbine is cooled in a heat exchanger called a condenser. Then it’s sprayed into the giant cooling towers and pumped back for reuse.
What is the function of boiler in power plant?
Boiler, also called Steam Generator, apparatus designed to convert a liquid to vapour. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect.
How do boilers generate electricity?
Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. … The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.
What is boiler efficiency?
Definition of Boiler Efficiency is “The percentage of the total absorption heating value of outlet. steam in the total supply heating value.” In other word, it is a rate how the boiler runs efficiently.
What are the main parts of a boiler?

How does the boiler work?
In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
Do boilers make electricity?
An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals.
Do nuclear plants use boilers?
The reactor is the heat source for the power plant, just like the boiler is for a coal plant. Uranium is the dominant nuclear fuel used in nuclear reactors, and its fission reactions are what produce the heat within a reactor.
