Generator flues

John J Doyle Ltd supply flue systems for power generators, CHP Units and turbines.

We supply modular twin wall insulated flues purposely designed for the exhaust of combustion gases from power generators. The GE Dinak Exhaust is designed to resist pressure up to 5,000 PA and comes in 4 different versions depending on the thickness of insulation.

The product range for power generators, CHP Units and turbines, incorporates an exclusive thermal expansion system that makes the installation of traditional expansion bellows unnecessary. The outer wall of the chimney has an expansion system at its male end to accommodate the expansion of the stainless steel resulting from the increase in temperature. The inner wall expands freely as the inner temperature increases, thanks to the inbuilt expansion absorption system.
