The performance of any thermal power plant depends on so many factors like coal quality, heat rate, cycle efficiency, design etc. The efficiency of any plant is not constant always but reduces years of years. Generally a coal fired thermal power plant efficiently performs for 25 years if all the required maintainance is done time to time.   Heat rate  - “Heat rate is the heat required to generate one unit of electrical energy.” Heat rate in a thermal power plant is measure constitute for its thermal efficiency. The plant output should be higher with minimum heat requirement so we can say that the heat rate must be as low as possible.                         The property of heat generation by fuel/coal depends on the calorific value. Also the CV(Calorific Value) depends on the elemental and non-elemental composition of coal. The analysis of coal composition a...

In power plant, most of the terms are called as short form of their actual. These are given below :   ATRS = Automatic Turbine Run-Up System ASTM = American Society for Testing of Material AOP = Auxiliary Oil Pump ACW = Auxiliary Cooling Water ACI = Automatic Control Interface AVGF = Automatic Valveless Gravity Filter ASLD = Acoustic Sound Level Detector APRDS = Auxiliary Pressure Reducing De-Superheating System AHP = Ash Handling Plant ATT = Automatic Turbine Test AVT = All Volatile Treatment ABT = Availability Based Tariff APH = Air Pre-Heater BMCR = Boiler Maximum Continuous Rating BFP = Boiler Feed Pump BFP = Boiler Fill Pump BEM = Bus Extension Module COC = Change Over Contact CI = Control Interface CDM = Clean Development Mechanism CCM = Clean Coal Mechanism CEP = Condensate Extraction Pump CW = Cooling Water CERC = Central Electricity Regularity Commission CEA = Central Electricity Authority COC = Cycles of Concentratio...
