6 FAQs about [Generator unit air outlet shaft]

How many GE generators are there?

Since the arly 1900s more than 10,000 GE generators have been shipped andplaced in service at utility companies and industrial pl nts, andas ship service units. The hydrogencooled units odirect water-cooled units. During the 1950s through t emid-1970s much emphasis was placed on developing units osup Figure 1. GE generator experience

What are the components of air turbine generating unit?

The nozzle section, accounting for quadrant, consists of 11 small nozzles .The blade of air turbine is made of glass fiber reinforced plastic, which is cheap and easy to be processed. PAN Hong-gang et al. / Energy Procedia 17 ( 2012 ) 1217 â€“ 1223 1219 Fig.2 Components of air turbine generating unit 1. Generator 2. Aft bearing box 3.Air turbine 4.

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.

How many air cooled generators are there?

More than 130 generators of these new designs have been shipped through the end of 1992, with approximately on -half in service. Theair-cooled generator product line iscontin-uing to evolve. The generator that is being applied with the LM6000 aeroderivative gas tur-bine (Figure 13) was tested and shipped in 1992.

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 control system work?

The control system is set to follow the inlet air temperature function. By contrast, the control system on aeroderiva-tives uses unbiased gas generator discharge tem-perature to approximate firing temperature. 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
