The main question I have is have you changed the stove from a single fuel to a different single fuel? Or can you use the stove on wood and then go to coal and if so with what modifications? Since you have modified it to burn wood which requires over the fire air just like Bit coal, can you bypass the Cat and burn Bit coal in it?
You may have hit on something here if it really is dual or triple fuel with minimal work for changeover.
When the really cold weather hits, I'm going to unbolt the top casting and remove the combustor from the stove before burning anthracite. From what I've read coal gasses will erode the catalyst coating on the combustor, rendering it useless. The chamber will remain in place except the bypass is no longer useful and there's no catalyst. The chamber will still act as a baffle and heat exchanger to, in theory, increase surface area and capture more heat from the coal gas before it goes up the chimney. And, in theory, a slightly lower temp would be witnessed in the flue.
As for bit. coal, I have absolutely no experience with bit, so I don't know.
