6 FAQs about [Generator core air outlet section]

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 type of cooling system did GE use?

This type of cooling system was GE's first proven design at gap pickup cooling. (See Figure 8.) The generator rotor and stator incorporated inlet and outlet sections along their axial lengths to achieve uniform cooling along the length of the generator field.

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 generator work?

a generator (such as silicon or petroleum by-products) can come from nearby operations or processes. While the inlet filters eliminate most of the contaminates from the air, the flow through the generator is so great that even a small percentage in the air stream equates to significant deposits over time.

How does a generator cooling system work?

The cooling system requires airflow supplied by a fan, which is either mechanically driven from the front of the generator’s ICE or is electrically driven. Cooling systems are designed to provide adequate cooling for full load operation at a specified ambient air temperature typically between 40C° (104F°) and 50C° (122F°).

How can a generator set be simulated?

Generator sets must be properly installed to ensure that cooling air is not restricted or artificially heated by nearby heat sources or from recirculation. Fortunately, installation influences can be simulated using software called Computational Fluid Dynamics. CFD is a software tool used to predict fluid flow, including thermal influences.
