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 […]

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. […]

New generation thermal power plants are larger in capacity and having sophisticated firing systems, which are more expensive. So it has become necessary to have a coordinated fuel burner management system. Why Boiler Protection System? Inside the furnace, for ignition purpose we generally use HFO (Heavy Furnace Oil), LDO (Light Diesel Oil) and Coal as […]

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) […]

Specific cause: Fault in the HT Motor Supply failure to feeding Bus Low Lube Oil Pressure (tripping of pump, low Oil level, Oil leak etc.) / High bearing temperature of motor/Fan bearings due to Lube Oil System Failure. High Bearing Vibration Process Failure (Cooling Water failure to the motor / Discharge Damper Closed) Control Room […]

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 […]
Consequences Pressure inside the Furnace will Increase Drum Level will start fluctuating(Sub-Critical Units) Flame will become Unstable Running I.D. Fan Motor current will increase Possible Causes Electrical System Failure (Fault in the HT Motor/Supply Failure in the Bus/High Winding Temperature) Lube Oil System Failure (Lube Oil Pump Failure/ Lube Oil Pressure Low) Bearing Temperature […]

Thermal Power Plant is based on the Rankine cycle and in Ideal Rankine cycle, there are 4 processes and those are Heat Addition at Constant Pressure in Boiler, Isentropic Expansion in Turbine, Constant Pressure Heat Rejection in Condenser and Isentropic Compression in Pumps. So now we will discuss about the condenser, which plays a very […]

Generators are the most expensive equipment in the whole plant and the generator faults are considered to be the serious since they may cause severe and costly damage to the insulation, windings and the core. They may cause severe mechanical damage to the shafts and couplings, thereby increasing the amount of fault damage. In the […]
