Exhaust pipe thimbles are the cleanest way to handle exhaust pipe penetrations through walls or roofs. Thimbles are designed to isolate the hot exhaust pipe from the structure, and to allow for a better termination at these penetrations. Important: Where the exhaust piping penetrates through a structure made of combustible materials, exhaust pipe thimbles are required by … Read more
Every emergency generator application includes an exhaust system designed to route exhaust gases out of the engine room. These exhaust systems consist of piping, elbows and, very importantly, flexible sections that must be used to account for the engine’s vibration, and also for the pipe growth experienced as the exhaust gases quickly rise to 800°F and more. If you are designing the exhaust system for an emergency generator, this article may keep you from making one of the most common mistakes that I see in the field.

The requirement for low exhaust noise in emergency power systems continues to be a hot topic for facility managers (and code enforcement officials!). In light of this demand, exhaust silencer manufacturers have designed ever-quieter solutions to abate noise, but a lack of consistency has remained in how silencers are rated for sound attenuation performance. The Electrical Generating Systems Association (EGSA), through a newly-published Standard, has now provided guidelines to address this issue.
