That unit should burn nut or nut and stove or maybe nut and pea over the top..
A few questions:
When you burnt coal last year, did the coal burn up completely, or did you have the fire go out, leaving unburnt and partially burnt coal??
How deep of a pile of coal did you have on the fire?? Coal burns from the bottom up, and it likes a DEEP fire.. a 3" deep layer of coal is almost guaranteed to go out.. Did you completely fill the firebox..did the coal fire completely cover the entire firebox, with no openings in the corners or on an end or side? ALL air going through the firebox MUST come up through the coal bed, none can be allowed through a loading door vent and no combustion air can be allowed to get around the fire on the sides or corners..
When you burn wood, do you have any problems getting the fire started, and keeping it burning??
Find someone in your area that has a stoker stove, they burn rice coal, sell them the rice coal,, your stove can't burn rice.. once you have the nut coal burning well, and can keep a fire all night long, then adding some pea size coal over the top of the burning nut coal does for some folks lengthen the burn time, but it also reduces the heat output, unless you increase the air to the fire, then it will burn a shorter time..
Hope this helps.. A photo or two of the firebox and grates/shaker mechanism would be helpfull too.
Some answers to your questions: The coal did not burn up completely, I had pieces left over after the fire died out. I build a coal sifter made out of wood and hardware cloth to sift the unburnt coal from the ashes. Is this wise to due or not?
The depth of the pile was not as deep as you suggested, I maybe had a 3" bed. And I also did not cover the entire firebox area. There were openings around the fire, I started out with a 1 pound coffee can full and started adding it one can at a time. Allowing 20-30 minites in between can fulls, so as not to smother the burning coals, and I did have openings around the edges where air was able to go around the fire.
When burning wood I had no trouble at all keeping a fire going.
