3. OVERVIEW OF BHEL
▪ BHEL was established in 1964.
▪ BHEL is one of the only 7 Public Sector Undertakings (PSUs) of India clubbed under
the esteemed 'Maharatna' status .
▪ On 1st February 2013,the Government of India granted Maharatna status to BHEL.
▪ BHEL is engaged in the design, engineering, manufacture, construction, testing,
commissioning and servicing of a wide range of products and services for the core
sectors of the economy, viz. Power, Transmission industry, Transportation (Railway),
Renewable Energy, Oil & Gas and defence.
▪ BHEL has 15 manufacturing divisions, two repair units, four regional offices, eight
service centers and 15 regional center.

5. BHEL HARIDWAR
▪ BHEL or the Bharat Heavy Engineering Limited is one of the largest engineering and
manufacturing organizations in the country and the BHEL, Haridwar is their gift to
UTTARAKHAND With two large manufacturing plants.
▪ It has established a Heavy Electrical Equipment Plant or HEEP and a Central Foundry
Forge Plant or CFFP in Haridwar
▪ The Heavy Electrical Equipment Plant in Haridwar designs and manufactures
turbogenerators, AC and DC motors, STEAM turbines, heat exchangers.
▪ The Central Foundry Forge Plant in Haridwar deals with steel castings and
manufacturing of steel forgings.
▪ Situated in Ranipur near Haridwar, the Bharat Heavy Engineering Limited employs
over 8,000 people.

10. TURBINE
▪ A turbine is a rotary mechanical device that extracts energy from a fluid flow and
converts it into useful work.
▪ The work produced can be used for generating electrical power when combined with a
generator.
▪ A turbine is a turbomachine with at least one moving part called a rotor assembly,
which is a shaft or drum with blades attached.
▪ Moving fluid acts on the blades so that they move and impart rotational energy to the
rotor.
▪ Early turbine examples are windmills and waterwheels.
▪ Gas, steam, and water turbines have a casing around the blades that contains and
controls the working fluid.

11. WORKING THEORY
▪ A working fluid contains potential energy (pressure head)
and kinetic energy (velocity head). The fluid may be
compressible or incompressible
▪ Impulse turbines change the direction of flow of a high
velocity fluid or gas jet. The resulting impulse spins the
turbine and leaves the fluid flow with diminished kinetic
energy.
▪ Reaction turbines develop torque by reacting to the gas or
fluid's pressure or mass. The pressure of the gas or fluid
changes as it passes through the turbine rotor blades.
▪ In the case of steam turbines, such as would be used for
marine applications or for land-based electricity generation
▪ In practice, modern turbine designs use both reaction and
impulse concepts to varying degrees whenever possible.

12. CLASSIFICATION OF
TURBINE
❖ Steam Turbine
❖ Water Turbine
❖ Gas Turbine
▪ On the basis of energy available at the turbine inlet :
1. Impulse Turbine
2. Reaction Turbine
▪ On the basis of fluid flow :
1. Tangential flow turbine
2. Radial flow turbine
3. Axial flow turbine
4. Mixed flow turbine

13. STEAM TURBINE
▪ Steam turbines are the prime movers of the steam powerplant that extract work from
high pressure , high temperature steam.
❖ STEAM TURBINE
Impulse Turbine Reaction Tubine

14. IMPULSE TURBINE
▪ Only impulse effect would be used to extract energy.
▪ Reaction effect is zero (0).
▪ High pressure , high temperature steam is provided to nozzle where enthalpy is
converted to K.E. and this energy conversion would have high velocity steam at entry
of turbine.
▪ Blades are symmetrical with constant area of cross section [ Vr1 = Vr2 ].
▪ Used for small power generation .
▪ For example : Pelton wheels and de Laval turbines

15. REACTION TURBINE
▪ Also called Impulse Reaction Turbine.
▪ Enthalpy and pressure changes takes place in blade as well.
▪ In nozzle enthalpy drop takes place and absolute velocity of steam increases.
▪ Non symmetrical blades are used.
▪ Used for large power generation.
▪ For example : Parson`s reaction turbine

16. CASING

17. CONCLUSION
▪ Summer training at BHEL Haridwar provided the idea of general awareness in steam
turbine manufacturing and its processes.
▪ It provided practical idea of manufacturing several components of turbine and their
practical applications.
