A turbine is just like a reversal of an electric fan or centrifugal pumps, while energy is used to turn the blades of fan and impellers of centrifugal pumps to produce the required energy, the turbine blade creates its own energy to be able to turn any mechanical device attached to it. For this reason, turbines work greatly where a large quantity of power output is needed. There are different types of turbines and the types depend greatly on how the blade of impellers of the receives its energy, among the types of the following are the most popular types:
These had been used for due to their ability to generate high power output. However, they still have their limitations which greatly rely on the energy source, for this reason, most countries have been seeking for higher power output which may be obtainable through the nuclear power supply.
In the other hand, a had been a popular type mostly used in the oil and , countries with a high quantity of will find it cheaper to operate their with due to the availability of the supply.
can simply be termed as employing a as the working fluid used to turn its shaft or impellers. It conventionally consists of compressors, a chamber, and the (where impellers are located). A can operate by burning either liquid fuel or fuel and basically converts pressure energy into mechanical energy. It should be understood that 2/3 of the power is used to drive the and that leaves only 1/3 of productive output.
Most gas turbines operate on an open cycle in which air is taken from the atmosphere, compressed in a centrifugal or axial-flow compressor, and then fed into a combustion chamber exit temperature low enough to allow the turbine to operate continuously. If the unit is to produce shaft power, the combustion products are expanded in the turbine to atmospheric pressure. Most of the turbine output is required to operate the ; only the remainder is available to supply shaft to a generator, pump, or another device.
In a , the is designed to provide just enough output to drive the and auxiliary devices. The stream of then leaves the at an intermediate pressure and is fed through a nozzle to produce thrust.
