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.

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.

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.

What temperature does a generator exhaust system emit?

Generator exhaust systems must also be engineered and properly installed to accommodate thermal expansion. Generator exhaust systems emit exhaust at temperatures anywhere from 500°F up to 1300°F depending on the unit size, manufacturer, and type of fuel burned.

How safe is a generator exhaust system?

Your generator set exhaust system must be installed safely, resulting in no recirculation of harmful exhaust gases back into your building’s HVAC system. The only way to ensure that your generator discharges exhaust gases safely is to use an exhaust system that has been designed properly.
