Why doesn't the temperature rise when the carbonization furnace burns charcoal?

First of all, look at the humidity of your own wood. If it is the wood that has just been cut down on the mountain, then the wood has a moisture content of 60%-80%. If you put it directly into the furnace to start ignition, then the temperature is more difficult. With the rising, it does not mean that it will not rise, but that the time is relatively long. It takes about 1-2 hours for ordinary wood to completely remove the moisture of the wood, and it takes about 4-5 hours for the temperature to slowly rise.

Second, check whether the thermometer on the device is broken. If it is broken, you need to replace it. Then there is the lack of heat that may be generated inside the furnace. At this time, it is necessary to continue heating at the bottom.

Third, check whether the front and rear moisture drainage holes of the furnace are blocked.
