    2. 2. Introduction of KSTPS<br />In April 1973, Central Electricity Authority prepared a Project Report for power station comprising of the two units of each of capacity 110 MW<br />The planning commission cleared the project report in Sept., 1976 for installation of two units each of 110 MW in first estimated cost of Rs. 143 Crores.<br />These two units was manufactured by BHEL, Hyderabad.<br />

    7. 7. GENERAL LAYOUT AND BASIC IDEA<br />The conversion from coal to electricity takes place in three stages.<br />Stage 1<br />The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat.<br />Stage 2<br />The second stage is the thermodynamic process.<br />The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant, boilers produce steam at a high pressure and temperature. <br />The steam is then piped to a turbine. <br />The high pressure steam impinges and expands across a number of sets of blades in the turbine. <br />
    8. 8. The impulse and the thrust created rotates the turbine. <br />The steam is then condensed and pumped back into the boiler to repeat the cycle.<br />Stage 3<br />In the third stage, rotation of the turbine rotates the generator rotor to produce electricity based of Faraday’s Principle of electromagnetic induction.<br />Control system of station is based on Rankin Cycle.<br />To increase the heat economy and efficiency we use number of modification in the plant.<br />

    29. 29. Coal handling broadly divide into three sections:<br />Wagon Unloading System.<br />Crushing System.<br />Conveying System.<br />
