Where to check the generator air inlet temperature

How hot does a generator set get?

The test sample in Table 1 shows the heating effect on the cooling air of a generator set with an enclosure fitted. At 18:24 in Table 1, the ambient temperature was reported to be 82°F. In this example, the maximum allowable top tank temperature is 230°F.

What is the ambient temperature of a generator set?

So at 18:24, the ambient capability = (230 – 198.3) + 82.0 = 113.7°F. In this case, the generator set can continue to operate at full load with an outside air temperature of nearly 114°F. When the ambient temperature is at the maximum 114°F (generator set ambient capability), the air temperature at the radiator core would be 148°F.

What is a good room temperature for a diesel generator?

The generator’s room temperature must be maintained at 18 to 27 degrees Celsius with 40 to 60% of relative humidity. Share This Story, Choose Your Platform! Patrick Paden is a generator specialist at Central States Diesel Generators.

Where should airflow be located in a gen set?

If air curtains are used, the airflow should gather this radiant heat just above the gen set, which offers greater efficiency and less exposure to high air velocities in other areas of the gen set room. Airflow should be upward around each engine or in the case of engines with mounted radiators, across the back of the engine to the front.

Does a generator set need an enclosure?

Fitting an optional enclosure to a generator set will lower its ambient capability as the cooling air flow will be restricted and heated. When specing a generator set with an enclosure for use in a hot climate, ambient capability is a top concern.

What is exhaust gas temperature / turbine inlet temperature?

The exhaust gas temperature or turbine inlet temperature indicates the health of an engine and when it has reached its maximum permitted load. There are many other useful operating conditions that may be monitored such as lubricating oil pressure and temperature, compressor delivery pressure, fuel pressure, and air intake temperature.
