About Generator cooling air inlet temperature
take in filtered, fresh ambient air and compress it in thecompressor stage. The compressed air is mixed with fuel in the combustion chamber and ignited. This produces a high-temperature and high-pressure flow of exhaust gases that enter in a turbine and produce the shaft work output that is generally used to turn an electric generator as well as powering the compressor stage. For typical 32o C water there is no de-rate for single-wall application. Ex: 32oC water + 8o C = 40o C incoming air. With 32o C water we typically can provide 40o C air back to the inlet side of the generator, so they are sized similarly to an ODP machine. Totally Enclosed Air-to-Water Cooled.

Inlet air fogging consists of spraying finely atomized water (fog) into the inlet airflow of a gas turbine engine. The water droplets evaporate quickly, which cools the air and increases the power output of the turbine.
Abstract. The article is focused on the comparison of impact of two different methods of inlet air cooling (vapor compression and vapor absorption cooling) integrated to a cooled gas turbine based combined cycle plant. Air-film cooling has been adopted as the cooling technique for gas turbine blades.
1.2 COOLING – Generator systems, above 15kW usually incorporate water-cooled prime movers, gasoline, gaseous or diesel. Water used to take away engine heat is cooled by fans pushing air through a radiator, remote or engine mounted. The higher the ambient temperature the greater the amount of air flow through the radiator is required.

6 FAQs about [Generator cooling air 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.
Can a cooling system be used with a generator set?
ibility of the cooling system with the generator set. Besides performance testing, endurance testing is t rejection: from jacket water and charge air coolerfactory provided cooling system will typically account for the entire system, a
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.
What is inlet air cooling?
Inlet air cooling improves performance of cooled gas turbine based combined cycle. Vapor compression inlet air cooling is superior to vapor absorption inlet cooling. For every turbine inlet temperature, there exists an optimum pressure ratio. The optimum compressor inlet temperature is found to be 293 K.
