6 FAQs about [Air inlet direction of air-cooled generator]

How does a 150 MW air-cooled turbine generator ventilation system work?

According to the practical structure of the ventilation system of the 150 MW air-cooled turbine generator, as shown in Fig. 2, a global flow resistance network is set up to determine the flows and pressures of the inlet and the outlet of the air cooling ventilation system.

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 does air temperature affect gen set cooling system sizing?

Altitude, air temperature and velocity greatly affect cooling ability and performance. Following are some rules of thumb that may be used in general gen set cooling system sizing exercises: For every 304.0m (1,000 feet) above sea level, deduct 1.38C (2 F) from the observed ambient temperature for a better indication of the air’s cooling ability.

What is a diesel generator air intake & exhaust system?

The diesel generator air intake and exhaust system (DGAIES) provides the diesel engine with combustion air from the outside. The combustion air passes through a filter and silencer before being compressed by a turbocharger and cooled by the coolant system before entering the individual cylinders for combustion.

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.

How does a radiant cooling system work?

Radiant cooling systems work by radiating heat from the inside of a machine through the enclosure, while an external fan pushes ambient air over the cooling fins on the outside. Mechanical Design IEEE: In this system, internal air flows over the core and windings and is circulated by a shaft-driven fan. Heat is radiated through the enclosure.
