A turbo generator is an electric generator connected to the shaft of a turbine (water, steam, or gas) for the generation of electric power. [ note 1 ] Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships.
This system used two large steam turbine generators to drive an electric motor on each of four shafts. The system was less costly initially than reduction gears and made the ships more maneuverable in port, with the shafts able to reverse rapidly and deliver more reverse power than with most geared systems.
The facility generates power by utilizing 32 Francis turbines each having a capacity of 700 MW and two 50 MW turbines, [1] totalling the installed capacity to 22,500 MW, more than twice the installed capacity of the largest nuclear power station, the Kashiwazaki-Kariwa (Japan) at 7,965 MW.
A 500 MW Siemens multi stage steam turbine with generator set (rear, red) A hydrogen-cooled turbo generator is a turbo generator with gaseous hydrogen as a coolant. Hydrogen-cooled turbo generators are designed to provide a low-drag atmosphere and cooling for single-shaft and combined-cycle applications in combination with steam turbines. [1]
A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam–electric power plants is due ...
Each unit is a Westinghouse cross-compound dual steam turbine-generator operating at supercritical steam conditions. At the time Keystone was constructed, Units 1 and 2 were the largest generating units in the world. Keystone was the first plant to be constructed away from a significant source of cooling water.
U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator [1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit.
The hot steam is sent through controlling valves to a turbine. As the steam expands and cools, its energy is transferred to the turbine blades which turn a generator. The spent steam has very low pressure and energy content; this water vapor is fed through a condenser, which removes heat from the steam.
