A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

I don't remember if there were sooting problems with bit, but there are people who burn bit here and they would be able to answer that. I would be especially careful of using anything that could burn downwards in the pipe while it sits idle. Pellets come to mind.
