6 FAQs about [Generator inlet and outlet air temperature difference]

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 happens if a generator passage is too large?

At low cold fractions, the desired result is a small stream of very cold air. If the generator passage is too large it will allow entrainment of some of the surrounding warm air and raise the cold outlet temperature. Therefore for any given vortex tube of a fixed total flow, there is an ideal opening size for every cold fraction.

How does a vortex generator work?

The remaining air is forced to the center of the hot tube creating a counter -current flow where, still spinning, flows back to the cold outlet. The air flows the entire length of the hot tube, through the center of the vortex generation chamber and to the cold outlet.

What does rotor inlet temperature mean?

Rotor inlet temperature (RIT): this term is sometimes used in North America, and means the same as SOT. Combustor outlet temperature (COT): this is the temperature at the first turbine nozzle guide vane leading edge. Turbine entry temperature (TET): this can have either of the above meanings. The standard definition for SOT, used herein, is:

What is the temperature difference between a gasifier dome and outlet?

Also, we can find that the gas temperature at top of the gasifier dome is about 80 K higher than the outlet temperature at least, and the temperature difference will increase with the O 2 velocity decreasing. Mengzhe Li, ... Qiu Wang, in Aerospace Science and Technology, 2021

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.
