Power Plant Boiler Schematic
After the steam passes through the steam turbine it is condensed in a condenser and again fed back into the boiler to become steam.
Power plant boiler schematic. This post is part of the series. It is used to deliver water to the boiler. This article explains how electricity is generated in thermal power plants. High pressure steam leaves the boiler and enters the turbine.
Steam boilers are boilers designed for a maximum allowable operating pressure mawp greater than 15 psig. These three most essential elements are coal air and water. B31 1 power piping code provides rules for most of the piping systems involved in a typical steam plant but has. The exhaust steam leaves the turbine and enters the condenser where heat is transferred from the steam to cooling water.
There are mainly three primary inputs given to a thermal power generating plants for producing electricity. Working of a power plant boiler. Heating the residential and industrial buildings. A thermal power generating plant works based on rankine cycle.
Thermal power station process flowchart and diagram. These are the devices which are used as integral parts of a boiler and help in running efficiently. Thus a thermal power station may sometimes called as a steam power station. The steam expands in the turbine and does work which enables the turbine to drive the electric generator.
Section iv of the asme code would provide rules for steam boilers with a mawp of 15 psig or lower. Schematic diagram of a steam power plant. Producing mechanical work by expanding it in steam engine or steam turbine and thermal power plants. Coal is fuel here because we are going to draw the flow diagram of.
This thermodynamic cycle is. As we supply the coal from coal bunkers via coal conveyors to be crushed into coal mills. The coal power plant diagram shows the components of the plant and the different stages of transforming the chemical energy coal into electrical energy as. We started with the boiler or the steam generation system.
This is known as ranking cycle. Boiler in a power plant has two functions. Performing certain processes in the sugar mills chemical and textile industries. The fuel is transported from mines via trains to the fuel storage facility in a power plant.
The combustion system converts energy in coal to heat. The fuel transported to the plant is generally bigger in particle size and before it is fed to the boiler furnace it is broken down into smaller pieces using crushers the fuel is then fed to the boiler generating a large amount of combustion heat. Coal fired power plant diagram.
