Generator flue systems are designed to safely remove high-temperature exhaust gases from diesel or gas-powered generators. These systems are essential for maintaining air quality, protecting nearby structures, and ensuring compliance with environmental and safety regulations. Whether installed in commercial buildings, hospitals, data centres, or industrial sites, the flue must handle intense heat, vibration, and corrosive byproducts.
Typically generator flue systems includes high-grade stainless steel pipework, thermal insulation, flexible expansion joints, and acoustic silencers. These components work together to manage heat dissipation, reduce noise emissions, and accommodate generator movement. Proper routing is essential to avoid excessive backpressure, which can impair generator performance or cause system failure.
Installation of generator flue systems must follow strict guidance on sizing, thermal expansion, termination points, and condensate management. The system should be designed to operate under positive or negative pressure depending on the setup, with due attention to weatherproofing and structural support. Regular maintenance access and compliance with UK legislation—including BS 6644 and clean air regulations—are vital for safe, long-term operation.
What Are Generator Flue Systems?
Generator flue systems are purpose-built exhaust pathways for safely venting combustion gases from standby or continuous-use generators. They manage high flue gas temperatures and ensure that emissions are safely discharged away from occupied or sensitive areas.
Key Design Features
A generator flue system typically includes insulated flue pipework, expansion joints, and noise reduction components. Materials such as 316-grade stainless steel are used to resist corrosion and withstand thermal stress, especially during frequent start-stop cycles.
Compliance and Safety
Systems must be designed to meet UK regulations, including requirements for exhaust velocity, termination height, and structural support. Safe discharge of fumes and regular inspection access are essential for ensuring long-term reliability and legal compliance.
