BHEL is the largest engineering and manufacturing enterprise in India in the energy-related today.
BHEL was established more than 50 years ago, ushering in the indigenous Heavy Electrical Equipment industry in India.
BHEL manufactures over 180 products under 30 major product groups and caters to core sectors of the Indian Economy.
BHEL has acquired certifications to Quality Management Systems (ISO 9001), Environmental Management Systems (ISO 14001) and Occupational Health & Safety Management Systems (OHSAS 18001) and is also well on its journey towards Total Quality Management.
BHEL Installed equipment for over 90,000 MW of power generation for Utilities, Captive and Industrial users.
Steam turbine:-
The modern steam turbine was invented in 1884 by the Englishman Sir Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kW (10 hp) of electricity.
Size of generators had increased from his first 7.5 kW set up to units of 50,000 kW capacity.
The interior of a turbine comprises several sets of blades, or “buckets”.
One set of stationary blades is connected to the casing and one set of rotating blades is connected to the shaft.
The sets intermesh with certain minimum clearances, with the size and configuration of sets varying to efficiently exploit the expansion of steam at each stage.

Characteristics of GAIL LPG:-
Processed from Natural Gas.
Has a high vapour pressure vis-a vis Refinery LPG.
Vapourises at atmospheric temperature and pressure .
Clean fuel with almost nil unsaturated compounds .
Has a higher calorific value than Refinery's LPG and hence gives more value for money.
Its homogeneous composition results in more efficient combustion.
