In order to generate electricity, we require mechanical torque and for the mechanical torque we require a fluid which will rotate the turbine, in thermal power plants to rotate the turbine we use steam as a medium. Steam is generated in boiler with the help of coal and water and after burning the coal, the […]
Based on the steam flow: Single-flow: the steam is admitted at the one end of the turbine in the first stage blades. Steam flows axially through the radially-mounted blades and exhausts at the other end after expansion (specific volume is increased). Double-flow: In this type of arrangement the steam is admitted at the center of […]
Efficiency Efficiency in turbine is defined as the ratio of the amount of work done by the turbine to the amount of heat transferred to the turbine by the working fluid and the efficiency at which the heat is transferred to the turbine rotating blades is dependent on the ratio of moving blade velocity and […]
Theory: The steam turbine is the most versatile prime mover, which is capable of almost endless applications. A machine, which originates mechanical motion by using some natural force, is called prime mover. Steam turbine is a practical power source and is built in as small size as 5 KW to as large as 1300 MW. […]
Here we have explained you how a thermal power plant works in both aspects theoretical as well as practical. Theory : Basically all thermal power plants works on the principle of Rankin cycle and Now a days most of the power plants work on the Rankin cycle principle with regenerative feed heating and reheat […]
