Lesson 2 Hydrogen Cooled Synchronous Generator Youtube A hydrogen cooled turbo generator is a turbo generator with gaseous hydrogen as a coolant. hydrogen cooled turbo generators are designed to provide a low drag atmosphere and cooling for single shaft and combined cycle applications in combination with steam turbines. [1] . Ge’s hydrogen cooled generator systems are the right fit for high efficiency applications and can operate in both simple and combined cycle power plants. their high power output makes them a more cost effective than solution than many water cooled machines. up to 755 mva. apparent power. up to 99.02% efficiency. 3,185 . installed fleet.
Hydrogen Turbine Generator Hydrogen was a new idea which really helped to improve the efficiency and cooling potential of large generators for several reasons: this drawing shows the unit 1 generator field (1935) which. Hydrogen cooled turbo generator. based on the air cooled turbo generator, gaseous hydrogen first went into service as the coolant in a hydrogen cooled turbo generator in october 1937, at the dayton power & light co. in dayton, ohio. [8] . Hydrogen cooled power generators are more efficient and have less mass of materials of construction than their air cooled cousins. hydrogen gas is 7 times more effective as a heat transfer medium than air and 1 14 th the density, resulting in less friction losses and more fuel converted to electricity. So why use hydrogen to cool a generator? despite its reputation, hydrogen gas has qualities that make it a superior heat transfer media and internal atmosphere for a generator. hydrogen is much less dense that air. cooling fans can move up to fourteen (14) times as much hydrogen as air using the same amount of power.
