In the boiler, the feed water and steam flows through the different parts where the pressure is much higher than the atmospheric pressure. These parts are generally known as Boiler Pressure Parts. Mainly the heat addition to the working fluid (Water) is done through these pressure parts. Following are the boiler pressure parts: Boiler Drum […]

Coal & Grading Coal is the primary fuel for the Thermal power plants, the reason coal is preferred more is that it is available in a larger quantity as compared to the other Non-renewable resources And apart from that, it is also cheaper and having a good calorific value. The coal is also categorized into […]

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 […]
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 […]
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 […]
Did you know! that there are only 11 thermal power plants in the world which are having an individual generation capacity of 5GW (5000 MW) or more around the globe and out of those 11 plants 8 power plants are in China, Japan and Taiwan. Taichung power plant in Longjing, Taichung, Taiwan (Capacity 5788 MW) […]
