In any thermal power plant, there are mainly three cycles i.e. Steam Cycle, Condensate cycle and Feed water cycle. We have already discussed the steam cycle in thermal power plant and now we will discuss about the Condensate cycle & Feed-water cycle. These two cycles are very important in efficiency point of view. As we […]

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 […]
The efficiency of a basic Rankin cycle is very less due to the enthalpy loss in the condenser. So the reheat and the regenerative cycle are used to increase the efficiency of the Rankin cycle.Here we will discuss how regenerative cycle is used in thermal power plant. (Rankin cycle with regenerative feed heating) If 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 […]

Definition: The main function of switchyard is to transmit & distribute the power at incoming voltage from the generating station and provide facilities of switching by the help of switchgears. Earlier we have explained about the various types of switchgears in our previous article.Switchyard is the point in the power network where transmission lines and […]
Boilers operating below the critical pressure are generally fitted with a steam drum, which is known as the heart of the boiler. In the steam drum, the main objective is to separate the steam from the steam-water mixture, which is coming through the riser tubes. Basically In the boiler, the feed-water comes through the feed-water […]
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. […]

Transformer is an electrical device whose main purpose is to transfer power from one electrical circuit to another circuit, but apart from this transformer is also a constant frequency, constant power and constant flux device. Transformer works on the principle of Faradays Law of electromagnetic Induction and it say that whenever there is a relative […]
Conventionally BOILER is a pressurised vessel which converts water in to steam. According to modern definition of boiler “it is a heat exchanger whose work is to produce high pressure steam from water”. In this heat exchanger, the hot side is the mixture resulting from the combustion of the fuel & air and the fluid […]
