| Gas Turbine Power Plant With Simple Layout |
A gas turbine plant may be defined as a plant in which the principal prime-mover is of the turbine type and the working medium is permanent gas.
A simple gas turbine plant consists the following below equipment:
✓Turbine.
✓A compressor mounted on the same shaft or coupled to the turbine.
✓The combustor.
✓Auxiliaries such as starting device, auxiliary lubrication pump, fuel system, oil system and
the duct system etc.
the duct system etc.
A modified plant may have in addition to above an intercooler, regenerator, a preheater etc.
The working fluid is compressed in a compressor which is generally rotary, multistage type.
Heat energy is added to the compressed fluid in the combustion chamber.
This high energy fluid, at high temperature and pressure, then expands in the turbine unit thereby generating slower.
Part of the power generated is consumed in driving the generating compressor and accessories and the rest is utilized in electrical energy.
The gas turbines work on open cycle, semi-closed cycle or closed cycle.
In order to improve efficiency, compression and expansion of working fluid is carried out in multi-stages.
Gas Turbine Power Plant Advantages :
Construction wise a gas turbine power plant is much simpler than a steam turbine power plant.
Gas turbine power plant is smaller than that of a steam turbine power plant.
It does not have any boiler like component. So, the accessories associated with the boiler are absent here.
It does not deal with steam. So, it does not require any condenser.
A gas turbine power plant can more instantly be started than an equivalent steam turbine power plant.
