What are the different auxiliary systems in thermal power plant?
Answer: Coal handling and storage, coal pulverizes water treatment plant, steam boiler, Drought systems, Ash Handling systems, Steam turbine, Circulation water system, Electrical Systems, Control and Instrumentation, Pollution Control equipment, and Fire Protection System
What is the purpose of Pulverizes?
Answer: Pulverizers serve two purposes, to dry the coal and to grind the coal. They crush the coal to size of 74microns
What are different types of Pulverizes?
Answer: Different types of Pulverizers are:
- Ball tube mill
- Ring roll mill
- Hammer mill
- Attrition type mill
What are different types of Steam boilers used in Thermal Power Plants?
Answer: Different type of boiler used in thermal power plants are:
- Fire tube boiler
- Water tube boiler
- Natural Circulation boiler
- Forced Circulation boiler
- Once through boiler
What is the largest pump in the thermal power plant?
Answer: In thermal power plant Boiler Feed Pump (BFP) is the largest pump, it delivers the water to the boiler.
What is Cavitation and disadvantages of Cavitation?
Answer: The formation of air bubbles and water vapour on the water surface due to the reduction in the pressure is called "Cavitation". When the pressure on the water reduces below the saturation pressure corresponding to the temperature of the water, the rapid formation of the water vapour and air bubbles starts. The bubbles suddenly collapse with the violent action and this collapsing pressure will be very high. The rapid formation and collapsing of bubbles causes the pitting of the metal surface. Cavitation also reduces the efficiency of the hydraulic prime mover causing the honey-combing of runner and blade contours which reduces the power output.
