Flue Dilution System at BCIT,

Some projects test not only our technical knowledge but also our teamwork. The BCIT NE6 Gas Lab was one of those.

Project details and overview

Client Served

BCIT

Location

Vancouver, British Columbia

Equipment Details

Duravent IVSI venting system and US Draft Co. control panels (V300 & V150)

Unlike standard gas-burning appliances, the combustion chambers here had no heat sink meaning flue gas temperatures could have exceeded 2500°F.                                                                                                                                                                                                                                To manage this safely, our team designed a custom flue dilution and venting system that:


Unique Aspects:

  • Introduced dilution air to cool flue gases to safe levels
  • Used a Duravent IVSI venting system lined with 2″ ceramic fiber insulation to withstand high heat across 8 stack.
  • Integrated US Draft Co. control panels (V300 & V150) with dual PID loops, continuously adjusting airflow for both temperature and pressure stability
  • Deployed a Single Blade Damper and CBX termination fan to maintain steady draft and negative pressure across the system

It wasn’t without challenges, but through persistence, collaboration, and innovation, the system is now stable and fully operational.

The BCIT NE6 Gas Lab was a technically complex project, with extreme flue gas temperatures and no heat sink. Raven Supply brought deep expertise and dependable support, helping us implement a safe, effective solution. Bennett was especially helpful in resolving challenges and unknowns with the existing flue vent strategies. Their team's dedication, open communication, and collaborative approach reflect the kind of partnership we value, one that builds trust, strengthens connection, and contributes to lasting impact.
