2. Introduction
• Turbines are hydraulic machines that convert energy into rotating
mechanical energy which in turn generators to produce electrical
energy
Pelton Turbine

10. Gas Turbine
The compressor sucks the air from the atmosphere and compresses it
and guides it to the combustion chamber.
11. Gas Turbine
This is an annular chamber where the fuel burns and is similar to the
furnace in a boiler. The air from the compressor is the Combustion air.
12. Gas Turbine
Stationary guide vanes of turbine direct the gases to the next set of blades
The kinetic energy of the hot gases impacting on the blades rotates the
blades and the shaft.
14. Types of Gas Turbine
A. On basis of combustion process:
1. Continuous combustion or Constant pressure type
2. The explosion or constant volume type
B. On basis of path of working substance:
1. Open cycle gas turbine
2. Closed cycle gas turbine
C. On basis of action of expanding gases:
1. Impluse turbine
2. Impulse- Reaction turbine
D. On the basis of direction of flow:
1. Axial flow
2. Radial flow
