6 FAQs about [Generator air inlet shaft area and size]
How much incoming air does a generator need?
A generator typically needs 35-40% over-sizing of the incoming air based on the internal generator inlet air temperature being ambient + 20 degrees Celsius. For typical 32 degrees Celsius water, there is no de-rate for single-wall application. The generator requires this amount of air for cooling purposes. For example, for every kilowatt of loss, the required flow is 1 gallon per minute.
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 is oversized?
For a typical 20°C rise over ambient for the internal cooling circuit, an example of internal air temperature would be 40°C ambient + 30°C = 70°C. The ambient air temp remains constant, and the generator needs 35-40% over-sizing to equal an ODP (Overall Design Point). This generator has cooling water inlet and outlets (TEAWC, CACW).
How does a gas generator work in a jet engine?
, and leading to the turbine section. In jet engines, the responsibility of a gas generator is to produce a high-pressure, high-temperature stream of combustion products (predominantly air), which are allowed to expand down to (ideally) the local
What are the parts of a gas generator?

How does a gas generator work?
The gas generator can operate at different speeds from the power turbine, and the power will actually increase as fuel is added to raise the moist air (due to humidity) to the allowable temperature. This fuel increase will increase the gas generator speed and compensate for the loss in air density.
