BHEL commissions country's first lignite-based thermal unit
The second unit of the project is also in an advanced stage of commissioning
Bharat Heavy Electricals (BHEL) has successfully commissioned the country’s first lignite-based 500 MW thermal unit of the two x 500 MW Neyveli New Thermal Power Project in Tamil Nadu. Also, it is the highest-rating pulverised lignite-fired thermal unit commissioned in the country so far.
The plant is based on Once-Through and Tower Type Boiler design, which has been adopted for the first time in the country for a lignite-based thermal unit. The plant is located in Cuddalore district of Tamil Nadu, and is owned by NLC India (NLCIL).
The second unit of the project is also in an advanced stage of commissioning.The order for boiler, turbine and generator (BTG) package for two units of 500 MW lignite-based thermal plant at Neyveli was placed on BHEL by NLCIL.
BHEL's scope of work in the project envisaged design, engineering, manufacture, supply, erection, testing and commissioning along with associated civil works of boiler, turbine and generator (BTG) and associated auxiliaries along with electricals, besides state-of-the-art controls and instrumentation (C&I) and electrostatic precipitators (ESPs).
The key equipment for the project has been manufactured by BHEL at its Haridwar, Trichy, Hyderabad, Ranipet, Bhopal and Bengaluru works, while construction of the plant was undertaken by the company's power sector, Southern Region, Chennai.
BHEL has established its engineering prowess in the past through successful delivery of higher-rated units of 600 MW, 660 MW, 700 MW and 800 MW thermal sets with a high degree of indigenisation.
