How to eliminate the problem of insufficient smoke extraction force in the high-temperature furnace?

Furnaces with long flue flue are prone to failure of insufficient extraction and unable to exhaust smoke during the drying process, because the temperature of the flue will gradually decrease in the later part of the flue. When such a failure occurs, the normal operation of the oven will be affected, and the working environment around the high-temperature furnace will also be deteriorated.

How to find the fault as early as possible so that the problem can be solved in the first time to minimize the loss? When the high-temperature furnace reaches the specified temperature, if the pressure in the furnace is large, a heat surge will occur when the furnace door is opened, and people will be subject to a strong thermal shock Feel unwell. This situation indicates that the flue gas in the furnace has not been discharged in time. If this phenomenon does not disappear when the flue gate is opened to the maximum, the most likely cause is insufficient pumping power. After the failure is observed, it can be at the flue exit after the gate is opened. Place a torch and observe the flame movement to further confirm.
