The explosion-proof door of the hot oil furnace trips frequently
Thread Content
The renovation of hot oil furnaces involves replacing the burner, ignition device, air preheating system, and air dampers. After operation, the explosion-proof door started to open frequently. I’d like to ask why; I hope experts can give some advice!
Is there secondary combustion (micro-explosion) in the flue? This needs to be thoroughly investigated – it’s a matter of safety, and no moment of relaxation is allowed~
Logically, when a device is modified in this way, the relevant safety accessories such as safety valves, explosion-proof doors, and rupture discs need to be recalibrated. In the current situation, it’s clear that your original explosion-proof doors are no longer suitable for the existing operating conditions!
The conditions are unclear; details such as the fuel type, furnace type, flue arrangement, and explosion-proof door placement are needed – please draw a diagram.
Thank you all for the comments; there are design flaws in the PID
