KSB
supplied valves for Bahr
KSB Group has supplied €2 million worth of valves to a new steam power plant
currently being built in Barh, in the Indian State of Bihar. The order was
awarded to the KSB Group who has previously supplied other Indian power stations
with valves and pumps. The complete order comprised 6,580 gate valves, globe
valves and check valves as well as other types of valves. About one third of
these valves are manufactured at the German KSB site of Pegnitz. A large number
were also made in KSB’s valves factory in India.
National Thermal Power Corporation (NTPC) built a state-of-the-art coal-fired
power station in Barh comprising three units each of 660 MW. It is a
supercritical steam power plant.
3,300 MW of coal-generated power has been added at Barh. The plant was
constructed in two stages with 1,980 MW in Barh I and 1,320 MW in Barh II.
For Barh I, NTPC awarded the contract to Russia-based power equipment supplier,
Technopromexport. The group was responsible for the design, manufacture, supply,
building and commissioning of the three power units for the turbine island.
Equipment for each machine was manufactured at Leningradsky Metallichesky Zavod
(steam turbines), Electrosila (turbogenerators) and Kaluga Turbine Works (feedwater
turbine-driven pumps).
The KSB Group produced 18 pump sets consisting of nine turbine- or
electric-driven boiler-feed pumps and nine condensate pumps. The biggest pump
sets have a drive rating of 18,000 kW each and generate a discharge pressure of
320 bar.
Yokogawa India supplied the turnkey automation and control system for the
boilers and associated equipment of three power generators. These include the
CENTUM CS 3000 R3 distributed control system, PRM plant resource manager, DPharp
EJA pressure/differential pressure transmitters and IR8A infra-red gas
analyzers.
(In May 2010, Mitsubishi Heavy Industries (MHI) and BHEL jointly won the order
to supply 18 pumps for units 1 and 2 of 1,320 MW Barh II project. They were
delivered in 2011.)
