I have feed at 5 teeth and 6 1/2 air, this coal needs alot of air. I clean fines from exhaust stack every 2 weeks. Has anyone experienced this and what did you do to correct it.
If the coal has a lot of fines it may have plugged the vent holes in the end of the pot-auger pipe. It could also have plugged some of the holes in the grates.
Also, if you are running only the pot auger pipe (24") and feeding it out of a drum, you will continue to have issues with fumes coming out of the drum. Some people make it work, but you must have good draft and keep the air around 4...any higher than that and there is enough pressure in the air chamber to push fumes back down the auger pipe.
