Generator exhaust air duct

Who designs and installs a generator exhaust system?

The proper design and functionality of a generator exhaust system falls on the responsibility of the engineering firm of record. If a field fabricated system is being utilized, the design and installation of the system must be a collaboration between the engineering firm and the installing contractor.

What is a generator set exhaust system?

A generator set exhaust system performs the same basic function as any other exhaust system - it provides a pathway for exhaust gases to escape into the air. However, there are a few special considerations to keep in mind for generator installations. Generators are often located indoors, so removing harmful exhaust gases is critical.

How do generator exhaust systems work?

Units located inside a building often require the exhaust to be routed up through the roof, up the side of the building, or to a free-standing stack. Generator exhaust systems for years have been fabricated from sections of schedule 40 carbon steel pipe that are field welded, then insulated to reduce surface temperatures.

Why do generator exhaust systems need to be properly designed?

Generator exhaust systems need to be properly designed to ensure correct engine performance and safe operation. System design has become more complex with the desire to keep emissions low, along with the desire to utilize the heat energy in the exhaust gas.

Where should a generator air duct be placed?

The air should flow over the entire generator horizontally, thereby cooling the alternator and effectively purging internal heat. As for the exhaust fans, they should be placed high and directly above the generator to extract heat and undesirable emissions. Air Duct: Duct systems are likely to require multiple turns.

Why do generators need air ventilation?

Air Cleanliness: Ventilation helps to remove harmful fumes and foul odors from any enclosed spaces. Generator rooms tend to be in need of air purging as buildup of engine exhaust and other output can be dangerous. Air ventilation systems can also play a role in generator noise reduction.
