Main cooling water is equipment cooling water for critical equipment like BFP, Compressor, Dryer, Lube oil cooler, Alternator cooler Auxiliary cooling water is used for cooling mainly for equipment coolig water through PHE
@@devivara1162 suppose running pump stops, by the time standby pump starts accumulator helps maintaining gradual decrease in pressure such that pressure reduce slowly as compared to without accumulator. accumulator provides enough time during pump changeover to prevent sudden pressure fall.
Sir what is difference between axcilary cooling water and main Colling water?????....and its uses in power plant?
Main cooling water is equipment cooling water for critical equipment like BFP, Compressor, Dryer, Lube oil cooler, Alternator cooler

Sir what is lube oil accumlator????when its uses???
To absorb fluctuations in oil pressure during operation
@@AS-wz7zz sir if pump oil pressure drop then how accumulator works???

Sir what r the reasons condenser is under negative pressure??
To increase heat drop in turbine and efficiency of system
