extracting the heat from the steam and turning it into work. The turbine usually drives a generator that turns the work from the turbine into electricity. The steam, used by the turbine, can be recycled by cooling it until it condensates into water and then return it as feedwater to the boiler. The condenser, where the steam is condensed, is a heat exchanger that typically uses water from a

Gas turbine engines derive their power from burning fuel in a combustion chamber and using the fast flowing combustion gases to drive a turbine in much the same way as the high pressure steam drives a steam turbine. A simple gas turbine is comprised of three main sections a compressor, a combustor, and a power turbine. The gas-turbine operates on the principle of the

Practical steam turbines come in all shapes and sizes and produce power ranging from one or two megawatts (roughly the same output as a single wind turbine) up to 1,000 megawatts or more (the output from a large power plant, equivalent to 500–1000 wind turbines working at full capacity). In the biggest turbines, in large fossil-fuel power plants, the steam pressure can be as high as 20

A Steam Turbine is a mechanical device that extracts thermal energy from pressurized steam and transforms it into mechanical work. Because the turbine generates rotary motion, it is particularly suited to driving electrical generators – about 90% of all electricity generation in the United States (1996) is by use of steam turbines [1] Wiser, Wendell H. (2000).
Since producing our first steam turbine in 1959, Fuji Electric has manufactured more than 464 steam turbines having a total combined output capacity that exceeds 23,619 MW, and has delivered these turbines to various countries throughout the world.
Calculation of the work output, boiler heat input and efficiency of this example becomes slightly more complicated, as in this case where work is done by two separate steam feeds to the turbine
In a steam power station, the electrical energy is produced according to the principle of “external combustion,” where the “heat of combustion” of the fuel is transferred to a prime mover by a “working medium.” In the steam generator, low-temperature water is the working medium that receives the heat of combustion of fuel and becomes high-energy steam. The heat of steam is
Steam turbine A device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves it after giving off the most of it.

Steam turbine: High pressure super heated steam is fed to the steam turbine which causes turbine blades to rotate. Energy in the steam is converted into mechanical energy in the steam turbine which acts as the prime mover. The pressure and temperature of the steam falls to a lower value and it expands in volume as it passes through the turbine. The expanded low pressure steam is exhausted …
All steam turbines can be classified into two categories; extraction (condensing) steam turbine and non-condensing steam turbine also known as back pressure steam turbines. Both of these steam turbine types have their own operating schemes and benefits which are described here in detail.
Steam turbines consist essentially of a casing to which stationary blades are fixed on the inside and a rotor carrying moving blades on the periphery. The rotor is fitted inside the casing with the rows of moving blades penetrating between the rows of fixed blades. Thus steam flowing through the turbine passes alternately through fixed and moving blades with the fixed blades directing the

How do steam turbines work? Explain that Stuff

A steam turbine generator works by heating water to extremely high temperatures until it is converted into steam, then the steam energy is used to rotate the blades of a turbine to create mechanical or rotational energy.
The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines.
