5.  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 turbo
generators, AC and DC motors, STEAM turbines, heat exchangers.
 The Central Foundry Forge Plant in Haridwar deals with steel castings and manufacturing
of steel forgings.
 The BHEL plants in Haridwar have earned the ISO - 9001 and 9002 certificates for its high
quality and maintenance. These two units have also earned the ISO - 14001 certificates.
 Situated in Ranipur near Haridwar, the Bharat Heavy Engineering Limited employs over
8,000 people.

8.  A steam turbine works on the principle
of conversion of High pressure & temperature steam into high
Kinetic energy , thereby giving torque to a moving rotor.
STEAM TURBINE

9. 1.High pressure turbine (H.P. Turbine)
2.Intermediate pressure turbine (I.P. Turbine)
3.Low pressure turbine (L.P. Turbine)
TYPES OF STEAM TURBINE

10. • High pressure and temperature fluid at the inlet of the turbine exit as lower
pressure and temperature fluid.
Specification of HP Turbine(500 MW)
Main Steam Temp- 537˚C
main steam pressure- 170 kg/cm2
Reheat steam temp- 537˚C
Length of Rotor - 4.61m
Height -2.15m
Weight -86400kg
HIGH PRESSURE TURBINE
(H.P. Turbine)

11. HIGH PRESSURE TURBINE

H.P TURBINE BLADES

13.  Intermediate pressure turbine having more pressure then L.P
turbine and lass than the high pressure turbine(H.P) . Its blade
is larger than high pressure turbine.
INTERMEDIATE PRESSURE
TURBINE

14.  The size of blades of I.P steam turbine is larger than H.P
steam turbine , but smaller than L.P steam turbine.
BLADE OF I.P TURBINE

15.  LP turbine is designed to be a dual flow turbine. Steam enters the centre of the
turbine from the crossover pipe and flows across the reaction blading in two
opposite directions. This configuration reduces axial thrust on the turbine and allows
for a smaller turbine installation.
Specification of LP Turbine(500 MW)
Main Steam Temp- 320˚C
Main steam pressure- 8 kg/cm2
Reheat steam temp- 320˚C
Length of Rotor - 8.71m
Height -10.7m
Weight-345000kg.
Low Pressure Turbine

16. LP TURBINE

17. Low Pressure Turbine

18. Titanium alloys offer high strength to intermediate
temperatures at a density almost half that of steel and nickel-
based super alloys. As a result, they have been adopted widely
in the fan and compressor stages of the gas turbine for both
disc and blade applications..
 LP blade is larger than HP & IP.
L.P TURBINE BLADES

23. Skoda Vertical CNC lathe
Finishing machining casings
including guide blade grooves
are carried out in vertical
position on this lathe. The
machine is provided with 840-C
CNC system.

24. CASING SHELL OR
CYLINDER

25.  ASTM A 356 Grade 1 for
cast carbon steel
 Nodular Cast Iron G40
 The reason is that cast
carbon steel is weld
repairable(LP turbine inner
casing rings,)
 1-2 Cr Mo steels –low
temperature steam
 Cast 9 Cr 1 –Mo- V –Nb
alloys
 9-12-cr Martensite /ferrite
steel
Casing Materials

27. CASING

28.  LOWER HALF (L/H)  UPPER HALF (U/H)

29.  Various operations consist in manufacturing of blades
of steam turbine.
 Check the raw material(Stainless Steel / Titanium
Alloy)
 Blanking-by blank saw m/c
 MILLING- width and thickness are maintained
