First, the water is filled into the boiler to fill the entire surface area of heat transfer. Working fluid cycle steam power plant is a closed cycle, which uses the same fluid repeatedly. For that reason, theyre called thermal heatbased power plants. Basic layout and working of a thermal power plant electricaleasy. In the starting of the plant, pulverized coal from mill machine supplied to. The boiler is essentially a closed vessel inside which water is stored. Steam power plants are widely utilized throughout the world for electricity generation, and coal is often used to. Working principle of steam powerplant power plant technology. When a high pressure motive fluid steam liquid enters the steam nozzle, this result in a decreasing pressure and increasing velocity of the fluid again the fluid enters in the diffuser which result in a increasing pressure and decreasing velocity of the fluid so due to pressure difference vacuum is created in between the nozzle and diffuser we can say venture throat. The operation of a thermal power plant is explained in a logical. Understand the layout and working principle of a steam power plant. This steam is used to rotate the turbine blade turbine shaft is connected to the generator. This tutorial explains about how thermal power plant works and what is the raltionship between thermal power station and rankine cycle. Power generation from steam has always been a more environmentfriendly way.
In thermal power plants, the heat energy obtained from combustion of solid fuel mostly coal is used to convert water into steam, this steam is at high pressure and temperature. A generating station which converts heat energy of coal combustion into electrical energy is known as a steam power station. Dm water is supplied by the boiler feed pump to economizer.
