*ALTERNATOR*<br /> Alternator is directly coupled with turbine and it convert mechanical energy into electrical energy. In this plant water cool alternator is used for generating electricity . Excitation system of alternator is brushless.<br />ALTERNATOR SPECIFICATION FOR 30MW .<br />11KV , 37.5MVA , 50Hz , 1500RPM , CONNECTION-Y , PHASE-3 , PF-0.8.<br />
*STEAM TURBINE*<br /><ul><li>With the use of boiler and then Steam Turbine makes the plant efficiency better.
The Steam Turbine comprises of one High Pressure Turbine and one Low Pressure Turbine.</li></li></ul><li>
*BOILER*<br /> Water tube boiler is used in this plant. Steam pressure at inlet is 102 kg/cm² & steam temp. at inlet is 535˚C. In this boiler , water is flow in the tube in furnace . Steam produces in tube & it collect in a drum which is situated on the top of boiler . Then steam goes to turbine .<br />
*ELECTROSTATIC PRECIPITATOR*<br />Electrostatic precipitator is consists of a large number of collecting electrodes. In it dust particles are charged and stick to the electrodes , hammer hit electrode and dust fall down . Dust is collect in base of ESP . Then dust is removed by air HOPPER. Transparent smoke find out in chimney .<br />
*POWER TRANSFORMER*<br /> To step-up or step-down the voltage and transfer power from one a.c. voltage to another a.c. voltage at the same frequency. <br />TRANSFORMER SPECIFICATION :<br /> 37.5MVA , 11/132KV , 50Hz , phases -3 , oil quantity-21725 ltr, cooling – ONAN:ONAF.<br />
