POWER GENERATION SECTOR
Power generation sector comprises thermal, gas, hydro and nuclear power plant business.
BHEL has proven turnkey capabilities for executing power projects from concept to commissioning. It posses the technology and capability to produce thermal sets with super critical parameters up to 1000MW unit rating and gas turbine-generator sets of up to 250MW unit rating. Co-generation and combined cycle plants have been introduced to achieve higher plant efficiencies. To make efficient use of the high ash available in India, BHEL also supplies circulating fluidized bed combustion boilers for thermal plants.
The company manufactures 220/235/500/540 MW nuclear turbine-generator sets. Custom – made hydro sets of Francis, Pelton and Kaplan types for different head discharge combination are also engineered and manufactured by BHEL.
The Company has proven expertise in Plant Performance Improvement through renovation, modernization and up rating of a variety of power plant equipment, besides specialized know-how of residual life assessment, health diagnostics and life extension of plants. BHEL built thermal sets consistently exceed the national average efficiency parameters and have achieved the highest ever Plant Load Factor (PLF) of 80.5% during 2007-08, which is 1.9% higher than the national average. Operating Availability (OA) was also the highest-ever at 86.7%.
BHEL is one of the few companies worldwide, involved in the development of Integrated Gasification Combined Cycle (IGCC) technology which would usher in clean coal technology. BHEL has set up Asia’s first 6.2 MW IGCC power plant with an indigenously designed pressurized fluidized bed gasified. The Company has also signed an MoU with APGENCO for setting up a 125 MW IGCC plant at Vijayawada.
INDUSTRIES
BHEL manufactures and supplies major capital equipment and systems like captive power plants, centrifugal compressors, drive turbines, industrial boilers and auxiliaries, waste heat recovery boiler gas, pumps, heat exchanger, electric machines, control equipment panels, seamless pipes etc… to a number of industries other than power utilities like metallurgical, mining, cement, paper, fertilizer, refineries and petro-chemical etc… BHEL has also emerged as a major suppliers of controls and instrumentation systems, especially distributed digital control systems for various power plants and industries.
Transportation
Most of the trains in Indian Railways, whether electric or diesel powered, are equipped with BHEL’s traction propulsion system and controls. The systems supplied are both with conventional DC drives and state of the art AC drives. India’s first underground metro at Kolkata runs on drives and controls supplied by BHEL. The Company also manufactures complete rolling stock i.e., Mainline 25 kV AC locomotives up to 5000 HP, EMU coaches and Diesel Electric Shunting Locomotives from 350 HP to 2600 HP. BHEL also undertakes retrofitting and overhauling of rolling stock. In the area of Urban transportation, BHEL is geared up for turnkey execution of electric trolley bus systems, light rail systems and metro systems. BHEL is contributing to the supply of electrics for EMUs for 15000V DC & 25 kV AC to Indian Railways. Almost all the EMUs in service are with electrics manufactured and supplied by BHEL. BHEL has also diversified into the area of track maintenance machines for Indian Railways.
