Rated air inlet temperature of air-cooled generator
Gas turbine inlet air cooling is one of the techniques suggested to enhance simple and combined cycle performance, particularly in hot climate operation. The power output and thermal efficiency decrease as the ambient temperature and humidity increase. However, the compressor inlet air temperature has the highest effect on the GT performance [26].

the base continuous ratings. The ambient temperature measured should be that of the cooling medium. In the case of an air cooled machine such as an AvK or STAMFORD alternator, this would be the air inlet air temperature. This may be higher than the surrounding air ambient temperature, due to the.
temperature is typically measured at the air inlet louver. The air flowing through the radiator, then, is significantly warmer than the air entering the system. In other words, the actual air on core temperature is higher than the cooling system temperature rating when the cooling system is rated at ambient. VENTILATION LAYOUT.
air temperature typically between 40C° (104F°) and 50C° (122F°). It is important to ensure that the ambient air capability is adequate for the site as operating above the rated ambient air capability may result in engine overheating, leading to a shutdown.
Why Cool Turbine Inlet Air? The primary reason turbine inlet air is cooled is to reduce or prevent the often significant loss of power output, compared to the rated capacity, of combustion turbines when ambient air temperature is high. TIC can even help to enhance CT output above its rated capacity.
6 FAQs about [Rated air inlet temperature of air-cooled generator]
What is a good inlet air temperature for a gas turbine?
For viability, they suggested an inlet air temperature of 15-25 °C. Mechanical chillers using centrifugal compressor with Freon refrigerant was used as an alternative inlet air cooling system in order to enhance the gas turbine power output in hot climates. The power output rises by 0.36% with each 1 °F inlet temperature reduction. 2.2.5.
How does inlet air cooling increase power output?
Inlet air cooling increases the power output by taking advantage of the gas turbine’s feature of higher mass flow rate when the compressor inlet temperature decreases. Different methods are available for reducing gas turbine inlet temperature. There are two basic systems currently available for inlet cooling.
What is gas turbine inlet air cooling?
Gas turbine inlet air cooling is one of the techniques suggested to enhance simple and combined cycle performance, particularly in hot climate operation. The power output and thermal efficiency decrease as the ambient temperature and humidity increase. However, the compressor inlet air temperature has the highest effect on the GT performance .
What is a cooling system rated for ambient temperatures?
turesCooling systems rated for ambient temperaturesWhen a cooling system is rated for ambient temperatures, it is the temperature of air on the inlet side of the system, before it picks up heat from the alt
What is the recommended air inlet cooling temperature?
The recommended air inlet cooling temperatures must not be below 7.0°C to safeguard against potential ice buildup in the compressor suction line . Majority of mechanical compression chillers involve more than one chiller unit. Other options such as steam driven compression are also used in industry.
How to obtain turbine inlet air cooling?
Two different methods are frequently employed to obtain turbine inlet air cooling: the evaporative cooling and inlet chilling systems , . Several works has been studied these cooling technologies as below detailed.
