Bosch natural gas burners often shut down in rainy weather
Thread Content
I would like to ask the experts: I have a Buderus natural gas burner used in a direct-fired drying oven. There is a small shelter installed outside it, but almost every time it rains, the burner shuts down a few minutes to several dozen minutes after ignition; however, it operates normally on sunny days. May I ask the reason?
Can water accumulate at the air inlet of the burner, and after ignition be heated and vaporized, resulting in a decrease in the oxygen content in the air?
The drying tower is of steel structure; the burner is located beneath a steel platform, and there is also a small canopy over the burner. Upon inspection, no significant water accumulation was found
Yours must be of the cold-air type; high humidity due to the weather conditions causes mist to form on the flame detector, which affects its performance. The flame cannot be detected, so it shuts down.
The 4th floor is the correct choice. It is recommended that you install an air preheater; otherwise, in rainy, snowy, or foggy weather, the engine will often shut down, which affects operation and poses safety risks；
