Bad Stove or Operator?

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

I'm not very familiar with sites like this or coal burning for that matter. My in-laws just gave me this Defiance volcano II wood coal add on. I am now very determined to make it work. It is in my shop 36x40 (all steel not heated full time.) I have tried anthracite with not much luck. Stove does well with wood. I have added a small fan to the draft box setup in the front of the stove that seems to help. Any advice is appreciated. Thanks in advance.

Here are some tips to get you going.

Anthracite coal is a completely different character than wood, so when burning coal forget everything you know. Once going, the firebox must be filled completely to the top of the firebox and no air can enter from above through vents or other means. It must all come from below the grates. It will need service about every 12 hours. Post some details or pics and let us know what the problems are that you are having.

I have really good luck with a hot wood fire. I have added small amounts of coal as suggested and sustained a fire for a few hours. But if I try to leave it over night without the forced air on, it will not hold a fire overnight. I am concerned about over firing the stove so I don't want to keep the fan on while it's unattended. I have a manual damper in the stack about 12" from stove. The stove has no firebrick in it or listed in the owners manual. The manual is very generic and covers this stove and 3-4 others and nothing about coal for any of them. The grates can be flipped over for different size ash to fall through and I have had them both ways. I would assume that for a hot fire I would want the smooth side of grates up and the side that has the channels for the small ash to lay in down. Inside the burn area there is a 3X4 box channel that runs from front to back on each side. There is a rod inside this that attaches to a plate that diverts the air from under the fire to over the top to the "secondary cumbustion chamber." Per your tip sheet I have been leaving the air box set so that it is entering from underneath. I will try and get some pictures in the next day or so.

Small amounts of coal is the last thing you want with anthracite. From what you describe, you may just be able to burn bituminous. I'm not real sure its a good idea to burn anthracite coal in it without firebrick. Any chance you can post some pics of this gem?
