Types of Turbine

Based on the mode of action of steam

• Impulse turbine : turbine that possesses the steam inlet having only kinetic energy.

• Reaction turbine :  if the steam available at the inlet having pressure energy as well as kinetic energy then this turbine is called reaction turbine.

According to flow of steam direction

• Axial flow turbine: if the steam flow through the runner in the parallel direction of the axis of the runner is called the axial flow turbine.

• Radial flow turbine : the steam flow through the runner in the radial direction of the off the runner.

Components of Turbines:

There are some common parts which mainly found in gas turbines.

• Combustor: combustor is the place where fuel is mixed with air & burned. For power turbine and produce thrust when passed via a nozzle high temperature exhaust nature types gas to be used.

• Air compressor: air filter is connected on to the inlet of the air compressor, air filter used to remove dust particles from inlet air. Rotating blades of shaft blocks the air which increase the pressure of available air and exit through the compressor outlet where high pressure air is available. Drive is used for operation of air compressor is through the belt drive system via the pump around their. This is cheaper option available for all compressor types.

• Any turbine system mainly consist of following section are described below:

• Air inlet section

• Compressor section

• Combustion section

• Turbine section

• Exhaust section

• Accessories section

Working of Turbine:

A moving fluid which is coming at inlet comes in contact with blades of turbine section. As the moving fluid strike with the runner of turbine thus energy of this incoming fluid is converted into rotational energy. Generator is equipped with shaft of the  turbine section. Shaft of turbine also rotates with the respective generator shaft. This generator is used to convert mechanical energy into electrical energy.
