6 FAQs about [Exhaust shaft and smoke exhaust shaft of generator room]

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.

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.

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.

What is the smoke shaft size?

●The Smoke Shaft should be sized at no less than 0.6m2with an aspect ratio of no greater than 2:1 and have a maximum pressure drop of 50 Pa between highest and lowest point. ●The shaft should be predominately straight, vertical, fi re rated to match the building requirements and well sealed against air leakage with a maximum leakage rate of 3.8m3

What is smoke shaft construction?

●Smoke Shaft construction is typically formed from either a fi re resistant shaft board, double thickness plaster board, blockwork or concrete. ●The Smoke Shaft should be sized at no less than 0.6m2with an aspect ratio of no greater than 2:1 and have a maximum pressure drop of 50 Pa between highest and lowest point.
