About What does generator inlet air temperature mean
Air entering the compressor at point 1 is com-pressed to some higher pressure. No heat is added; however, compression raises the air temperature so that the air at the discharge of the compressor is at a higher temperature and pressure. Upon leaving the compressor, air enters the combustion system at point 2, where fuel is injected and .

power and high electricity occur, the inlet air cooling techniques are very useful for reducing the inlet air temperature and thus improving power output and efficiency. It is observed that an increment of 1°C in the compressor air inlet temperature decreases the gas turbine power output by.
The results show that the gas turbine inlet air temperature could be reduced in a range of 4 °C–35 °C for almost 9 months. The maximum efficiency enhancement results from using a mechanical chiller system and approaches 5%.
Gas turbine (GT) performance is primarily dependent on the inlet air temperature. The power output of gas turbine is dependent on the flow of mass through the gas turbine. This is why at hot weathers with less dense air, the power output drops, but at cold weather with high dense air, the power output rises.
Air density is inversely proportional to temperature, meaning that rising temperatures decrease air density and therefore reduce gas turbine efficiency and power. Inlet-air cooling, especially in warm and hot environments, is commonly used to compensate for the efficiency loss caused by high air temperature.

6 FAQs about [What does generator inlet air temperature mean ]
Does inlet air cool a gas turbine increase power?
The exact increase in power available a particular gas turbine as a result of inlet air cool-ing depends upon the machine model and site altitude as well as ambient temperature and humidity. However, Fig. 37 can be used to make an estimate of this benefit for evaporative cool-ers.
What happens if a generator gets hot?
When it gets hot the opposite effect occurs. Power output decreases due to less mass flowing through the turbine. Ambient temperature also has an affect on the compressor. Colder air improves compressor efficiency. This means the compressor consumes less power, leading to more power supplied to the generator.
What are the requirements for a gas turbine inlet temperature regulator?
The gas turbine inlet temperature regulator has strict requirements for the resistance of the air flow outside the tube. Generally, the operating resistance is required to be controlled below 150 Pa, which requires that the air flow speed should not be too high.
Can gas turbine inlet air temperature be reduced?
They concluded that the gas turbine inlet air temperature was reduced by 4–25 °C and the performance could be improved in a range of 1%–3.5% in one gas turbine for almost 9 months.
What is turbine air inlet cooling?
Turbine air inlet cooling is one of many available commercial methods to improve the efficiency of an existing gas turbine. The method has various configurations which could be utilized for almost all installed gas turbines.
What is a gas turbine inlet temperature control system?
These systems include methods for intake heating under low loads and intake cooling under basic loads, which can be used to change the intake temperature of the compressor under a variety of operational conditions. The heat exchanger of gas turbine inlet temperature control system is a key equipment.
