What is the working principle of a turbine?
Turbine is a rotary mechanical device that extract the potential energy and Kinetic energy of fluids and convert into mechanical energy. The working fluid may be gas, steam or liquid. When the fluid directed to the rotor by nozzles, due shapes of blades, fluid imparts momentum/ a rotational energy to the rotor.
What is the working principle of gas turbine engine?
The basic operation of the gas turbine is a Brayton cycle with air as the working fluid: atmospheric air flows through the compressor that brings it to higher pressure; energy is then added by spraying fuel into the air and igniting it so that the combustion generates a high-temperature flow; this high-temperature …
What are the principles of operations of open and closed gas turbines?
In the closed cycle gas turbine the same working fluid is circulated again and again within the turbine but in the open cycle gas turbine the working fluid i.e. air is replaced again and again while flowing through the gas turbine.
What is the operating principle of steam turbine?
In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into steam. The potential energy of the steam is thus turned into kinetic energy in the rotating turbine’s blades.
What are the applications of gas turbine power plant?
Applications of Gas Turbine Power Plant
- It is used to drive the generators and supply peak loads in steam, diesel or hydro plants.
- To work as combustion plants with a conventional steam boiler.
- To supply mechanical drive for auxiliaries.
- Used in ships and jet aircraft.
Which is main component in gas turbine plant?
Compressor
Explanation: The main component of a Gas turbine plant is Compressor. 7.
What are the 3 main components of gas turbine?
Gas turbines are composed of three main components: compressor, combustor and power turbine. In the compressor section, air is drawn in and compressed up to 30 times ambient pressure and directed to the combustor section where fuel is introduced, ignited and burned.
What is the principle of water turbine?
Turbines are usually fixed in place, so when a fluid flows through it there is a drop in pressure at the back edge of each blade that causes the turbine to turn. The principle is the same for air or water and the faster the medium is moving, the greater the pressure drop, and the faster the turbine spins.
What is principle of steam turbine and what are the different types of steam turbines?
According to the working principle,there are different types of steam turbine. ⇨When steam strikes the moving blades through nozzles called Impulse Turbine and when it strikes the moving blades under pressure via guide mechanism called Reaction Turbine.
What are the components of gas turbine power plants?
What is the cycle used for gas turbine plants?
Basic combined cycle One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle. The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle.
What is the working principle of gas turbine power plant?
The fundamental working principle of a gas turbine power plant is same as that of a steam turbine power plant. The only difference is there that in steam turbine power plant we use compressed steam to rotate the turbine, but in gas turbine power plant we use compressed air to turn the turbine.
What happens to the gas coming out of a gas turbine?
The hot gas coming out from the combustion chamber is then passed to the turbine where it expands doing mechanical work. Part of the power developed by the turbine is used to drive the compressor and other auxiliary equipment, and the remaining is used for power generation. The gas coming out of the turbine is exhausted to the atmosphere.
What are the different parts of a gas turbine?
Although the operations of a gas turbine are complex, there are three essential parts: the compressor, the combustion system, and the turbine. The compressor works by pulling air into the engine, which is then pressurized and fed into the combustion chamber at up to several hundreds of miles per hour.
Which type of air compressor is used in gas turbine power plant?
Rotary type air compressor is used in the gas turbine power plant. At the inlet of the compressor, filtration of the air has been carried out from the dust due to the air filter. Compressor plays the role of compressing the air and increasing the pressure of the air.
