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.

GAIL (India) Limited

Gas Authority of India was renamed GAIL (India) Limited on November 22, GAIL (India) Ltd. (Gas Authority of India Ltd), India's principal gas transmission and marketing company, was set up by the Government of India in August 1984 to create gas sector infrastructure for sustained development of the natural gas sector in the country. The 2800-km Hazira-Vijaipur-Jagdishpur (HVJ) pipeline became operational in 1991.

During , three LPG plants were constructed and some regional pipelines acquired, enabling GAIL to begin its regional gas distribution in various parts of India GAIL began its city gas distribution in Delhi in 1997 by setting up nine CNG stations, catering to the city's vast public transport fleet. In 1999, GAIL set up northern India's only petrochemical plant at Pata.

6, GAIL (India) Limited has been ranked no.1 company among gas utilities in Asia. Among Energy Companies, which include companies other than Gas utilities also, GAIL has been ranked 22nd in overall performance in the Asia region. GAIL’s Net Profit for the second quarter of the FY increased by 30 percent to Rs. 924 crore. Employees:- 5,000

Products:- Natural gas Petrochemical Fuel Lubricant

Natural gas:- Natural gas is a gas consisting primarily of methane, typically with 0-20% higher hydrocarbons primarily ethane. It is found associated with other fossil fuels, in coal beds, as methane clathrate. It is an important fuel source and a major feedstock for fertilizer.

No Impurities like sulphur, carbon dioxide, traces of oxides of nitrogen. Hence lower corrosion. Has nil moisture content. Customer-friendly fuel as it is easy to transport, store and use.

LPG :- GAIL produces LPG through fractionation, known as Straight Run (SR). GAIL LPG is an eco-friendly fuel and provides a cheaper and effective means of reducing pollution and increasing productivity.

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.

Natural gas production by countries in cubic meters per year.

GAIL POWER:- The Combined Cycle Power Plant comprises of two Gas Turbines (52 MW each), one Steam Turbine (52 MW) and 2 Heat Recovery Steam Generators. Commercial production was declared with the commissioning of the Gas Turbines in open cycle mode in December 2001.

Gail turn over :- GAIL’s Turnover increases 32% to Rs. 23,776 crore in from Rs. 18,008 crore in Net Profit up 8% at Rs. 2,804 crore. GAIL surpasses physical performance targets in natural gas, polymers and liquid hydrocarbon segments. The Gross Margin during the year increased by 8 percent to Rs. 4,851 crore from Rs. 4,506 crore.

The Net Profit during was Rs. 630 crore against Rs. 722 crore in the corresponding period last year, mainly due to lower price realization. GAIL continued its excellent physical performance as per its Annual Performance.
