I think someone asked if this is a chimney vented stove or power-vented. It seems the feed works fine, and the air is sure puffing up the fire, but my .02 says too much air is being sucked or blown through the grate, OR there is an air adjustment wide open.
Either way, I'd be shutting things down unless you want a hopper fire. (You don't) If your feed rate were that great, and the fire as intense as you picture indicates, it would be 110 degrees in the room where the stove is.
First look for an air adjustment, or hopefully someone who knows Alaska's will chime in, but you sure don't want 50 lbs of rice coal on fire in the hopper. "The Hook and Ladder Co" might not be as gentle as you can be.....plus all the paperwork, questions, satellite truck...anti coal guys picketing......
