Steam Turbine Generator (STG) in combined cycle
Steam turbines in combined cycle applications are specifically developed as multi-pressure condensing types, using water cooling provided from a cooling tower or air cooler, and direct coupled to a generator and optimized for reheat.
Steam Turbine
The steam energy spins the turbine blades. (5) The generator is attached to the steam turbine by a rotating shaft. As the steam turbine spins, the generator spins and creates electricity. (6) The steam that uses it''s energy to spin the turbine
How do steam turbines work?
Condensing turbines (used in large power plants to generate electricity) turn the steam at least partly to water using condensers and giant concrete cooling towers. This allows the steam to expand more and helps the

Heat Recovery Steam Generator (HRSG)
The second island is the HRSG steam turbine generator set. The HRSG absorbs heat energy from the exhaust gas stream of the combustion turbine. The absorbed heat energy is converted to thermal energy as high temperature and
6 FAQs about [The role of cooling air in steam turbine generators]
How long does it take to cool a steam turbine?
can take up to 3 days. The forced-air cooling is based on the counter air flow (see Fig.2), where the cooling air enters the steam turbine from the low pressure section. The blower skid is connected to the turbine casing via a flexible hose, which can be connected to
How does a condensing steam turbine work?
Condensing steam turbines (CSTs) exhaust steam to a condenser at atmospheric pressure or the lowest possible pressure at which it can be condensed with the available cooling utility (Figure 1b). In locations with a ready supply of water, cooling is usually accomplished via a closed loop that circulates through an evaporative cooling tower.
How does a low pressure turbine cooling system work?
The air is delivered to distribution channels through collector channels, which are connected to the main air supply duct, which in turn provides air to the cooling system of a low-pressure turbine. In the typical low-pressure turbine casing cooling systems, the distribution channels are connected with collector channels by welding.
How can turbine cooling systems improve engine efficiency?
The application of turbine cooling systems (ACC) helps to increase engine efficiency, reduce specific fuel consumption (SFC), and reduce NOx and CO emissions. This research received no external funding. The authors declare no conflict of interest.
What is a steam turbine generator?
A steam turbine generator is defined by the various system components, such as: HP-IP-LP turbine, generator, lubrication and hydraulic oil system, gland steam supply, vacuum breaking and drain systems, and turbine measurement, protection and control system.
What is a combined cycle steam turbine?
Steam turbines in combined cycle applications are specifically developed as multi-pressure condensing types, using water cooling provided from a cooling tower or air cooler, and direct coupled to a generator and optimized for reheat.
