  1. 1. INTRODUCTION: BHEL is the largest engineering and manufacturing enterprise in India in the energy related infrastructure sector today. BHEL was established more than 40 years ago when its first plant was setup in Bhopal. BHEL is one of India’s nine larger Public Sector Undertakings or PSUs ,known as the NAVRATNAS or the nine jewels . The wide network of BHELs 14 manufacturing division, four power Sector regional centre, over 150 project sites, eight service centre and 18 regional offices. BHEL has already attained ISO 9000 certification for quality management, and ISO 14001 certification for environment management
  2. 2.  The power plant equipment manufactured by BHEL is based on contemporary technology comparable to the best in the world and is also internationally competitive. BHEL is the only company in India with the capability to make simultaneous for power plants, defense and other applications.
  3. 3. HEAVY ELECTRICAL EQUIPMENTPLANT:1. BLOCK-1: Electrical Machine Shop2. BLOCK-2: Heavy Fabrication Shop3. BLOCK-3: Turbine Manufacturing Shop4. BLOCK-4: CIM (Coils & Insulation Manuf.)5. BLOCK-5: Condenser Fabrication & Forge Shop6. BLOCK-6: Fabrication Shop & Die Shop7. BLOCK-7: Carpentry & Heat Treatment Shop8. BLOCK-8: Heat Exchanger Shop
  4. 4. BLOCK-3: TURBINE MANUFACTURINGSHOP HMS (Heavy Machine Shop) Assembly Section OSBT Turbine Section Blade Section
  5. 5. STEAM TURBINE: Turbine is an engine that converts energy of fluid into mechanical energy . Steam turbine depends completely upon the dynamic action of the steam. Steam turbine is steam driven rotary engine.
  6. 6. WORKING OF STEAM TURBINE:Impulse Turbine:-• steam is expanded only in nozzles.• Blade passage of constant cross-section area.Reaction Turbine:-• Pressure drop in fixed & moving blade.• Blade passage of varying cross-section area.
  7. 7. ROTOR AND CASING OF STEAMTURBINE: HP (High Pressure) IP (Intermediate Pressure) LP (Low Pressure)
  8. 8. GAS TURBINE: Gas turbine have been used for electricity generation. The gas turbine obtains its power by utilizing the energy of burnt gases & air which are at high Pressure and Temperature.
  9. 9.  For electricity generation, it is known as power turbine. For propulsion unit in aircraft, it is called aircraft turbine.
  10. 10. BLADES MANUFACTURING: Operations Performed On Blades: Inspection Cutting Milling Grinding on both the surfaceo Machining Of Blades: Horizontal milling machine Central lathe machine CNC machine Vertical boring machine
  11. 11.  Mostly 500MW turbine blades are manufactured in this shop. Basically the design of blades is classified according to the stages of turbine. The size of LP Turbine blades is generally greater than of HP Turbine blades.
  12. 12. OVER SPEED BALANCINGTUNNEL:Features: max. thickness of tunnel : 2500mm tunnel diameter : 9000mm min. vibration limit : 1micron over speed limit : 2500 to 4500 rpm rotor balancing of max. : 600Mw rating type of pedestal : DH 90/ DH 12
  13. 13. CONCLUSION:- BHEL is the largest engineering and manufacturing enterprise in India . The company manufactures 235 MW nuclear turbine generator sets and in future it will 500 MW. BHEL is a major contributor of equipment and systems to industries. At the all, till now BHEL is best in supply and manufacturing products.
