What is the output of gas turbine?
A large single-cycle gas turbine typically produces 100 to 400 megawatts of electric power and has 35–40% thermodynamic efficiency.
What is the efficiency of the turbo generator?
Turbine exergy efficiency increases from turbine power of 500 kW up to 2700 kW, and maximum exergy efficiency was obtained at 70.13% of maximum turbine developed power (at 2700 kW) in each operating point. From turbine developed power of 2700 kW until the maximum power of 3850 kW, exergy efficiency decreases.
What does a turbo generator do?
A turbo generator is a turbine connected to a generator, which together transform the mechanical energy of a moving fluid, such as liquid water, steam, natural gas or air, into electricity. Turbines vary significantly depending on their application; they can be used to harness the power.
What is a gas turbine generator?
A gas turbine is a combustion engine at the heart of a power plant that can convert natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that produces the electrical energy that moves along power lines to homes and businesses.
What are the 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 working fluid of a gas turbine engine?
In air standard cycles as in gas turbine cycles, the working fluid is air. In the open cycle gas turbine, air enters a compressor where its pressure is increased. The compressor therefore inputs work to the working fluid (positive work).
What is the rating of turbo alternators?
Explanation: The turbo alternators are one category among the synchronous machines. They are driven by steam turbines. The rating of the turbo-alternators is 3000 rpm.
What are turbo alternators and where are the widely used?
Turbo generators are used for high shaft rotational speeds, typical of steam and gas turbines. The rotor of a turbo generator is a non-salient pole type usually with two poles.
Where are turbo generators used?
Large steam-powered turbo generators provide the majority of the world’s electricity and are also used by steam-powered turbo-electric ships. Small turbo-generators driven by gas turbines are often used as auxiliary power units (APU, mainly for aircraft).
What is meant by turbo alternators?
The alternator which coupled directly to the steam turbines are called turbo-alternator . The turbine converts heat energy in the steam into mechanical work and the alternator converts mechanical energy into electrical energy .
How does gas turbine generator work?
As hot combustion gas expands through the turbine, it spins the rotating blades. The rotating blades perform a dual function: they drive the compressor to draw more pressurized air into the combustion section, and they spin a generator to produce electricity.
What are the 3 main component of gas turbine?
What are the constituents of the exhaust gases?
Constituents of Exhaust Gases From Internal Combustion Engines The exhaust gases from internal combustion engines are complex mixtures consisting principally of the products of complete combustion, small amounts of the oxidation products of sulfur and nitrogen, and compounds derived from the fuel and lubricant.
What’s the average CHP of a gas turbine?
, overall CHP efficiencies for gas turbines are typically in the range of 65% to 70%, although higher efficiencies can be achieved depending on site specific conditions and engineer- ing design configurations.
How many megawatts are in a gas turbine?
Gas turbines are available in sizes ranging from approxi- mately one to more than 300 megawatts (MW) and are used to meet diverse power needs, including propulsion (e.g., aircraft, ships, and trains), direct drive (e.g., pumps and com- pressors) and stationary electricity generation.
Why is the temperature of exhaust gas important?
Exhaust gas temperature (EGT) is important to the functioning of the catalytic converter of an internal combustion engine.
