Greenhouse gasses (GHGs) have suffocated the world since 1820, the beginning of the industrial revolution. This dying world of ours is home to more than 8.5 million species. Out of these 41,415 species are on IUCN Red List and 16,306 endangered due to the adverse climate conditions. Accord de Paris was the agreement within the […]

Want to know about the various processes involved while starting a unit? Then you are at the right place because we have stuffed all the details involved in the start-up of a Sub-critical Tangential Firing unit. Below we have explained the start-up procedure types and various processes involved in case of tangential fired sub-critical boiler […]

What is Protection Relay? A relay is nothing but a sensor, which senses an abnormal condition of an electrical circuit and closes its contacts. These contacts in turns close and complete the circuit breaker trip coil circuit which trips the circuit breaker by isolating the faulty portion of the electrical system from the healthy portion. […]
Boiler Drum is a very crucial part in case of Sub-critical boilers. It is cylindrical in shape and situated at the top of the boiler. In Super-critical units, water is directly converted into steam so drum is not required, but in case of subcritical boilers, the whole water quantity is not directly converted into steam. […]

Large thermal power plants generate electricity by using the thermal energy of fuel. Most of the power plants are pulverized coal fired boiler that means thermal energy is generated by the combustion of pulverized (crushed) coal.In order to control the combustion process,every power plant has their Burner Management System/FSSS(Furnace Safeguard Supervisory System) system,but Optimum efficiency is […]

Alternator,when connected to the grid, it is preferred to operate it in lagging Power Factor mode and in lagging power factor mode it delivers Reactive power and Active power to the grid and the rotor speed is same as that of grid frequency, which is 3000 RPM as per 50 Hz in India.Loss of excitation will […]

What is RMF? RMF stands for Rotating Magnetic Field and in case of a 3-Phase supply system whenever the 3-phase windings(R/Y/B) are physically displaced by 120 degrees along the periphery and are electrically being fed from a 3 –phase supply which are time-displaced by 120 degrees electrically. Then we have three mmf (Magneto Motive Force) […]

In our previous articles, we have explained you the Water Cycle of thermal power plant. This Water cycle consists of Feed Water Cycle and Condensate Water Cycle. Condensate water cycle is from Condenser to the Deaerator and feed water cycle is from Deaerator to the Boiler Drum. Impact of Dissolved gasses in Feed-water It is an utmost necessary […]

Any device that is capable of continuous electro-mechanical energy conversion is known as an Electrical Machine. Therefore, transformer is not an electrical machine. It is simply a Static Device which transmits power from one circuit to another at different voltage levels and same frequency. In case, the voltage level also remains the same, it is […]
