  1. 1. A SEMINAR PRESENTATION ON Kota Super thermal power station ELECTRICAL ENGINEERING SKIT, JAIPUR Presented By :Rohit Pareta
  2. 2.      Kota Super Thermal Power Station is coal based steam plant. It Is Located on the left bank of Chambal river in Kota (Rajasthan). Total generation capacity is 1240MW. Required 250 hectares land. The project was proposed By the Central Electricity Authority and production start in 1983.
  3. 3. Good transportation Network. Abundant amount of water. Nearest to load center. Good geographical features to built a plant. Availability of land to build new units . Availability of both skilled person and labor.

  8. 8. OVERVIEW OF COAL HANDLING PLANT Row coal from Bharat coal ltd. Dhanbad & bilaspur(MP) To KSTPS from Gurla via a single railway track Wagon trippler Coal size reduced by 20 mm Bunkers Crusher house Hoppers Raw coal feeders CONVEYING SYSTEM Coal mills (pulverization) BOILER FURNACE
  9. 9. COAL HANDLING PLANT • The Coal Received from BHARAT COKING COAL LTD. DHANBAD & SOUTH EASTERN COAL FIELD LTD. BILASPUR(M.P.) by train. • Everyday 3- 4 trains of coal are unloaded, each train consists 58 wagons. •Specification of conveying system: oBelt width : 1400mm oSpeed : 2.2m/sec oTotal install power : 360kw oCapacity : 1350/750 ton/hr oNo. of conveyor: 38
  10. 10. Boiler • It is a closed vessel in which water under pressure is converted into steam. • Hot water or steam used to transfer heat to a process. • A boiler is always designed to absorb maximum amount of heat released in process of combustion. • Furnace:- It is primary part of boiler where the fuel is burnt to liberate the heat energy.
  11. 11. Overview of Boiler DM water Boiler water tubes & various stages Super heated steam Flue gases Air from environment via draft fans Pulverized coal Boiler furnace Ash handling plant
  12. 12. Types of Boilers • Fire tube boiler • Water tube Boiler
  13. 13. Boiler at KSTPS
  14. 14. Super heater • Super heater consists group of tubes. • The tubes are heated by the heat of combustion gases during their passage from furnace to chimney, so the temperature increased. • Super heater remove the moisture from the steam leaving from the boiler tubes. Economizer • Economizer is a device which recover the heat from the flue gases on their way to chimney. • It increases the 10-12% efficiency of the plant.
  15. 15. Super Heater and Economiser
  16. 16. Air Pre-heater • Function- To raise the tempreatur of air. • Benefits- Increase the efficiency of plant. • Type- Plate, Tubular, Regenrative. • KSTPS uses Regenerative type.

  18. 18. TECHNICAL DATA OF 110 MW TURBINE • • • • 1. 2. 3. 4. Rated output : 110 MW. Economic output : 95 MW. Rated speed : 3000 rpm Direction of rotation viewing from : Clockwise the front bearing pedestal. • 5. Rated temperature of steam before : 535oC the stop valve. • 6. Maximum temperature of steam before : 545oC the stop valve.
  19. 19. TECHNICAL DATA OF 210 MW TURBINE • Rated Output : 210 MW. • Rated Speed. : 3000 rpm. • Main steam pressure. : 150 Kg./Cm2 • Main steam temperature. : 535oC. • Reheat steam temperature. : • Weight of turbine. : • Overall length. : 535oC. 475 T approx. 16.975 Mtrs. approx.
  20. 20. Cooling System • In KSTPS hydrogen cooling system is employed for generator cooling. • Hydrogen is used because of its superior cooling properties & low density. • Thermal conductivity of H2 7.3 times of air. • Seal oil system are used in turbine for less friction in bearing. • Water cooling also used for any kind of fire.
  21. 21. WATER TREATMENT PLANT The principle problem in high pressure boiler are corrosion and steam impurities. These impurities form deposite over turbine blades and nozzeles. Corrosion costs power station crores rupees in repair.

  23. 23. Water Treatment Plant  Pressure filter removes undisclosed impurities from raw water.  Carbon filter removes excess chlorine from clarified water.  D.M. plant removes dissolved impurities from clarified water.  Conductivity ,pH & silica content of this water must be checked time to time.

  25. 25. ASH HANDLING PLANT This plant can be divided into three sub plants as follows :- 1)Fuel and Ash Plant:It is specially designed for bottom ash and fly ash in electro static precipitator economizer and air preheaters hoppers. 2)Air and Gas Plant:The flue gases after passing through the ElectroStatic Precipitator is exhausted through chimney.
  26. 26. 3) Ash Disposal and & Dust Collection Plant:Dry free fly ash is collected in two number of 31 fly ash hopper which are handled by two independent fly ash system.

  31. 31. Advantages • The fuel used is quite cheap. • Less initial cost as compared to other generating plants. • It can be installed at any place irrespective of the existence of coal. The coal can be transported to the site of the plant by rail or road. • It require less space as compared to Hydro power plants. • Cost of generation is less than that of diesel power plants.
  32. 32. Disadvantages • It pollutes the atmosphere due to production of large amount of smoke and fumes. • It is costlier in running cost as compared to Hydro electric plants. • The overall efficiency of thermal power plant is less then 40 %. • Disposal of ash is major problem.
