BHEL synchronizes 490MW Unit at Dadri power plant

This is the first indigenous unit equipped with a high temperature reheat steam turbine which has been designed for operating at a higher reheat steam temperature of 565 degree Celsius aimed at reducing the consumption of coal.

Bharat Bharat Heavy Electricals Ltd, or BHEL, said it had successfully synchronized the first 490MW unit at the National Capital Thermal Power Project or NCTPP Stage-II, at Dadri in Uttar Pradesh. This reiterates its commitment to the success of the Commonwealth Games to be held in October, 2010 in New Delhi.

This is the first indigenous unit equipped with a high temperature reheat steam turbine, which has been designed for operating at a higher reheat steam temperature of 565 degree Celsius aimed at reducing the consumption of coal. The unit also comprises an advanced control, instrumentation and monitoring system.
The order was placed by NPTC to set up 2 sets of 490MW each at NCTPP. BHEL’s scope of work included manufacture, supply, erection, testing and commissioning of the main plant package for two units of 490 MW each.
NTPC has declared commercial operation of the unit. The second unit is also in an advance stage of erection and is expected to go on stream in time, the company said.

Notably, BHEL has also recently achieved drum lifting milestone of the Heat Recovery Steam Generator at the 1,500 MW Pragati-III Combined Cycle Power Plant, coming up at Bawana in New Delhi, thereby achieving a major milestone towards supplying power to the Commonwealth Games.

For the Commonwealth Games, BHEL is also executing contracts for several other power projects, including Koderma STPS (2x500 MW), Mejia STPS (2x500 MW) and Durgapur Steel STPS (2x500MW) of DVC and Jhajjar STPS (3x500 MW) of APCPL, in addition to Dadri STPS (2x490 MW) of NTPC and Pragati-III CCPP (1500 MW) of PPCL.

In a related development, BHEL has commissioned a captive gas-based power station at a refinery in Oman. The 26-MW Gas Turbine Generator was put on stream at the Oman Refinery and Petrochemical plant in Muscat, an official statement said.

This is the second such unit to be commissioned by BHEL at the refinery. Another unit of similar rating was commissioned at the same project in May, 2010.
The Gas Turbine Generator units were engineered, manufactured and supplied by the company’s Hyderabad Plant, while the control system has been supplied by its Bangalore unit. Oman is a key export market for BHEL with several benchmark references established by the company, including installing 16 Gas Turbine sets with a cumulative capacity of more than 1,250 MW in the west Asian country alone.
At present, BHEL is executing 45 contracts in 23 countries, which include major turnkey projects in Bangladesh, Bhutan, Libya, Syria and Sudan.
