high temperature furnace exhausts the exhaust gas insufficiently

How to eliminate the problem of insufficient exhaust gas extraction in the process of drying up the high temperature furnace?

The furnace with longer flue gas flue is prone to the failure of insufficient extraction during the drying process, because the temperature in the back section of the flue will gradually decrease. Such a failure will affect the normal operation of the oven, and will also worsen the working environment around the high-temperature furnace.

How to find the fault as soon as possible so as to solve the problem as soon as possible so as to reduce the loss?

When the high-temperature furnace reaches the specified temperature, if the air pressure in the furnace is large, there will be heat waves when opening the furnace door, and people will feel uncomfortable due to strong thermal shock. The occurrence of this situation indicates that the flue gas in the furnace is not discharged in time. If the phenomenon does not disappear when the flue gate is opened to a large extent, the most likely cause is insufficient pumping force. After the fault is observed, a torch can be set at the flue outlet to observe the flame trend for further confirmation.

Stack fuel at the entrance of the flue at the bottom of the flue, and the fire will lead out the flue gas in the furnace, which can eliminate the fault of insufficient exhaust power.
