Generator room exhaust fuse valve

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.

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.

Do generator exhaust systems need to be insulated?

Generator exhaust systems are insulated to reduce the amount of heat radiated to the mechanical space, chase, and chimney. Based on the system routing, a risk of direct contact to the system by maintenance or repair personnel must also be considered. The maximum exhaust gas temperature determines the amount of insulation required.

Why should you choose a prefabricated generator exhaust system?

Let us show you how. Prefabricated generator exhaust systems have emerged as the preferred choice over traditional field-welded assemblies. These systems offer significant advantages, including time savings, cost-effectiveness and enhanced safety when dealing with high temperatures and exhaust gas pressures.

What temperature should a field fabricated generator exhaust be insulated?

To protect potential personal contact with the system, the outer shell temperature must be below 140°F. These temperature calculations can and should be performed by the UL listed manufacturer based on specific product design criteria. Field-fabricated generator exhaust also requires insulation.
