My concern is that during a cold day, that the stove may experience an outfire, caused by the rice coal sticking to the hopper sides.
My first thought is to spray the sides of the hopper with PAM cooking spray. Would that lessen the surface tension and allow the coal to flow more freely?

Perhaps a better design might be to make the bottom edges at say a 30 degree angle and then it would empty out completely if your coal is dry like mine is. My Anthraking (Pocono 110K) has the same 200 pound hopper and the same problem. They offer a 320pound hopper which is probably standard on the 220K stove. I opted against it as the ash pan has the capacity to handle a 300 pound burn load but I don't want to deal with the weight and bulk. So 200 pounds is fine until I work out how to automate the ash emptying. Automation is fine but I feel better about inspecting things every morning but I guess that is just me.

The coal's not damp or wet. When I stack the bags I jab the bottom corner with a screwdriver so they drain if wet.
I have a couple of idea's on how to fix this besides my previous mentioned thoughts. The simplest idea is to just paint the sides and back of the hopper with several coats of gloss black paint. If that fails to remedy this sticky situation, I work at an Industrial Park and could have the inside of the hopper Electrocoated with paint which would make the inside of the hopper as slippery as a wet p@$$y after four glasses of wine.
I thought about an electric vibrator for the hopper but I can foresee several problems with that. First, the carpet could potentially become overwhelmed with an avalanche of coal if a sudden release of coal were to happen, but maybe not because that would be the same as loading the hopper? Second, the vibration could cause the coal to feed down the grate.
