I hve a shelter furnace tht burns coal and wood. I'm having 2 burn wood with coal 2 get my furnace hot, coal by itself will not cut it and it burns up real fast. I live n owensboro ky so my coal comes from Sampson coal which is good quality. I'm just lost at wht I'm doing wrong.

Welcome here to the Coal Forum Nice hearing from Kentucky!
Coal doesn't need much air like the wood does. Your sending all the heat up the stack.
Cut your air way back and be patient...coal is super slow to react to changes.

Some report hunks work very well, give them a try for sure.
Your key damper (MPD) will do fine if you don't have overly strong draft there.
Learning how best to use that key damper will determine how good you get make the fire do what you want it to do.

This is where the key damper needs learned...be careful and don't leave it too open, plus you would want to be sure and let some top air in for a while to burn off the gases produced above the fire after reload time.

I think thts my problem is tht draft is 2 strong once it gets going good bc whn I burn the wood and coal together the flames still move fast like it's getting air. Will coal burn with all the air cut off or will it go out. I wanna try shutting the draft knob all the way whn it gets going but dnt wanna kill it
