3. Introduction
•Ramgarh gas thermal power station is the first gas thermal power
plant of Rajasthan.
•Power station houses the GAIL terminal for the supply of gas
fuel. ONGC, OIL and Focus Energy Ltd. are among the gas
suppliers.
•It has a staff of more than 200 engineers and technical workers.

4. GASTURBINE
• A turbine driven by expanding hot gases produced by burning
fuel, as in a jet engine.

5. Working Principle
• Instead of using the heat to produce steam, as in steam turbines,
gas turbines use the hot gases directly to turn the turbine blades.
• Gas turbines have three main parts:
i) Air compressor
ii) Combustion chamber
iii) Turbine

6. Simplified Prototype Of GasTurbine

7. Stages Of Operations
•Air is compressed(squeezed) to high pressure by a compressor.
•Then fuel and compressed air are mixed in a combustion
chamber and ignited.
•Hot gases are given off, which spin the turbine wheels.

8. Layout Of GasTurbine

9. Waste Heat Recovery Steam Generator

10. Advantages Of GasTurbine
•Less Maintenance Cost.
•It is simple in construction. There is no need for boiler,
condenser and other accessories as in the case of steam power
plants.
•Cheaper fuel such as kerosene , paraffin and benzene can be
used which are cheaper than petrol and diesel.
•Gas turbine plants can be used in water scarcity areas.

11. Disadvantages Of GasTurbine
•Low thermal efficiency due to the fact that 66% of the power
being generated is utilized in driving the compressor!
•The running speed of gas turbine is in the range of (40,000 to
100,000 rpm) and the operating temperature is as high as 1100 –
12600C. For this reason special metals and alloys have to be
used for the various parts of the turbine.

12. Applications Of GasTurbines
•Gas turbines are used to drive pumps, compressors and high speed cars.
•Used in aircraft and ships for their propulsion. They are not suitable for
automobiles because of their very high speeds.

Ahh,Those turbines were like
Poetry in motion….
