Get a muck tub, it will hold about 2 bags of coal, fill it up and let it sit a day before going into the stove, that will allow it to dry a little. The coal will still be a little damp, which is what they recomend. Right out of the bag Blashak coal is pretty wet.
I cut a hole in the bottom of my muck tub and laid a piece of plastic screen oner it to let air come up through the coal. I have no rust in my Channing stoker hopper, in my second season burning it.
Also I use a metal feed scoop to load my hopper, keeps the dust down.
