Kota super thermal power station ppt, rtu

  1. 1. A SEMINAR PRESENTATION ON ELECTRICAL ENGINEERING UNIVERSITY COLLEGE OF ENGINEERING ,KOTA RAGHAV CHITTORA VII th semester Electrical Engg. Mr. S.K. Sharama Mrs. Seema Agrawal (Asst. professor) Guided By :- Presented By :- Kota thermal power station
  2. 2. KOTA SUPER THERMAL POWER STATION
  3. 3. INTRODUCTION KSTPS is first coal based power plant in Rajasthan. It is located ideally on the left bank of CHAMBAL River at the upstream of KOTA BARRAGE. Its first unit of capacity 110 MW is commisioned on 17 jan 1983 and last one on 2009. It is one of highest power generating plant with installed capacity of 1240 MW.
  4. 4. STAGES Unit 6 – 195 MW Unit 1 – 110 MW Unit 2 – 110 MW Unit 3 – 210 MW Unit 4 – 210 MW Unit 5 – 210 MW Unit 7 – 195 MW Stage I Stage II Stage III Stage IV Stage V DESIGN 110 + 110 + 210 + 210 + 210 + 195 +195 = 1240 MW
  5. 5. CONTENTS OF THE PRESENTATION • GENERAL LAYOUT • COAL HANDLING PLANT • PROCESS OF STEAM GENERATION • TURBINE • GENERATOR • WATER TREWATMENT PLANT • SWITCHYARD • CONTROL PANNEL
  6. 6. PLANT OVERVIEW
  7. 7. COAL HANDLING PLANT • 20000 tons coal requirment per day. • The main coal sources are: 1. Coal India Ltd. (CIL) 2. South Estern Coalfield Ltd. (SECL) 3. Northern Coalfield Ltd. (NCL) (coal comes from 1000 km distance) • Everyday 3- 4 trains of coal are unloaded, each train consists 58 wagons.(approx 3500-3800 tons) • Coal is unloaded from wagons by means of WAGON TRIPPLER • Stock yard Capacity -5.0 lack tons • Secondary fuel :-oil (HSD/ LDO)
