  • 1. Presentation on barauni thermal power station Anish anand geu
  • 2. ABOUT B.T.P.S Barauni Thermal Power Station is an existing 320 megawatt coal-fired power station owned by Bihar State power generation company limited (BSPGCL). The power station is located at Begusarai district, Bihar, India.  Barauni thermal power station in Bihar came into existence in association with the Russian collaboration in the year 1962.
  • 3. coal is supplied from Rajmahal coal field and Urma Pahari tola,Jharkhand. Currently two new units VIII and IX are under construction which will increase the power output by 500MW. The equipments are supplied by BHEL , Bhopal. The electricity generated here is sold to North Bihar Power Holding company Ltd.
  • 4. GENERATION UNITS AT B.T.PS There are total seven units in B.T.P.S Two units are currently working producing total o/p of 220 MW. Unit no. V and VII are undergoing renovation and modernization. The capacity of plant will be increased to 500 MW in next 5 years.
  • 5. Thermal power plant A generating station which converts heat energy of coal combustion into electrical energy.
  • 6. Working principle
  • 7. LAW OF CONSERVATION OF ENERGY Chemical energy of fuel Heat energy in furnace Heat energy of medium water Kinetic energy of turbine rotor Electromotive force Electricity generation
  • 8. Division of a thermal power plant Coal Handling Plant Water Treatment Plant Fuel and Ash Plant Feed Water and Steam Plant Cooling Water Plant
  • 9. Constituents of thermal power plant Steam generating equipment Condenser turbines Cooling towers Electrical equipments
  • 10. Steam generating equipment Boiler Boiler furnace Superheater Economiser Air preheater
  • 11. condenser It condenses steam at exhaust of turbine. It creates very low pressure at the exhaust of turbine which helps in converting heat energy of steam into mechanical energy in prime mover. The condensed steam can be used as feed water to the boiler.
  • 12. turbines It is used as prime mover to generator. Three types of turbine are used : 1.HP turbine 2.IP turbine 3.LP turbine
  • 13. Electrical equipments Generator : To generate electricity Transformer : For required voltage Switch yard : Onward transmission of powers
  • 14. Why coal as a fuel Coal can provide usable energy at a cost of between 12 to 15 % compared to oil and natural gas, and coal prices are relatively stable. Coal is inherently higher polluting and carbon intensive than other energy alternatives. However coal is so inexpensive that one can spend quite a bit on pollution control, and still maintain coal’s competitive position.
  • 15. Types of water required DEMINERALISED WATER : BOILER SOFTEN WATER : COOLING AND GENERAL SERVICE DRINKING WATER : DOMESTIC PURPOSE UNTREATED WATER : ASH HANDLING,COAL HANDLING AND FIRE FIGHTING
  • 16. observations B.T.P.S has a very good working environment. B.T.P.S is very sincere about cleanliness and hygiene. It has got a Technical training centre with very good learning environment. Staff is excellent and supportive and always ready to help.
  • 17. conclusion It is third largest thermal power plant of Bihar. It generates 210 MW electricity and after completion of extension project it will produce 500 MW electricity. It is major contributor of electricity to 7 districts of north Bihar.
