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 BHEL's 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
INTRODUCTION:

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.
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.
ROTOR AND CASING OF STEAM TURBINE:
HP (High Pressure) IP (Intermediate Pressure) LP (Low Pressure)
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.
For electricity generation, it is known as power turbine.
For propulsion unit in aircraft, it is called aircraft turbine.
BLADES MANUFACTURING:
Operations Performed On Blades: Inspection Cutting Milling Grinding on both the surface
o Machining Of Blades: Horizontal milling machine Central lathe machine CNC machine Vertical boring machine
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.
OVER SPEED BALANCING TUNNEL: 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
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.
