6 FAQs about [Air-cooled generator inlet temperature]

What is a good air temp for a generator?

For a generator, the internal inlet air temperature is typically 35-40 degrees Celsius higher than the ambient temperature. This is known as the Overdesign Temperature Rise (ODP). The generator does not require any de-rating for single-wall applications with typical cooling water temperatures of 32 degrees Celsius.

What is the ambient temperature of a generator set?

So at 18:24, the ambient capability = (230 – 198.3) + 82.0 = 113.7°F. In this case, the generator set can continue to operate at full load with an outside air temperature of nearly 114°F. When the ambient temperature is at the maximum 114°F (generator set ambient capability), the air temperature at the radiator core would be 148°F.

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.

What is turbine inlet air cooling?

Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine. The direct consequence of cooling the turbine inlet air is power output augmentation. It may also improve the energy efficiency of the system.

How to select the optimal inlet air cooling system for intercooled gas turbines?

It is important to note that the optimal inlet air cooling system for intercooled gas turbines can be selected through a thermo-economic analysis that factors in different ambient temperatures and the ISO relative humidity level of 60%. Fig. 9. Required cooling capacity for an inlet air cooling system. 6.2. Inlet air temperature drop

What are the best ambient conditions to incorporate inlet air cooling?

1. The best ambient conditions to incorporate inlet air cooling are high ambient temperature and low ambient relative humidity which yield better performance of gas turbine and combined cycle than that without inlet air cooling. 2.
