Why does vacuum in steam condenser reduce or drop??

  1-High exhaust temperature: Vacuum drops or maintains at lower side due to high exhaust steam temperature flow into steam condenser. This high exhaust temperature is mainly due to 1-Operation of Turbine at lower loads 2-More clearance in labyrinth seals 3-Not operating exhaust hood sprays 4-More load on condenser 5-Breaking of ejector U loop 2-Low circulating cooling water flow Vacuum in condenser reduces due to inadequate cooling water flow through steam condenser. This is mainly due to; 1-Problems associated with pumps 2-Air pockets in pipe line 3-Leakages in cooling water line 4-Stuck of discharge valve of pump 3-High cooling water temperature at condenser inlet Higher cooling water temperature at condenser inlet results into reduction of vacuum due to poor heat transfer from steam to water 4-Poor heat transfer in condenser Very less or poor heat transfer in steam condenser reduces vacuum to very low level resulting into high exhaust temperature &am

Introduction to power plant

A power plant also referred to as a power station and which generates power, it is an energy producing source and the final form of energy being converted is electrical energy. Power plant is one of the most vital sectors for any country or industry. In this competitive world nothing will move without the  electric power, be it an industry, home, office etc.So such an important sector needs to be operated and maintained very dexterously, efficiently and safely. Based on the primary source of energy power plant are of following types; Wind power plants:  Primary source of energy is natural wind, the speed of win is being utilized to produce electric energy. Solar power plants:  Primary energy is the energy received from the sun that again is converted into electric energy. Hydal power plant:  As the name indicates primary source of the energy is Hydro-water Tidal power plant:  Energy present in the tides is utilized for producing the electric energy Geothermal power p
