For anthracite coal to burn, the only source of combustion air must come from below the coal bed. The ash from the coal must be able to 'shaken' out from under the fire, so the grate needs to be able to move to allow the ash to fall below the fire, and into a removable ashpan.

Unless you can create the above items, I doubt that you will sucessfully burn anthracite coal in your stove. I'd go to several of the major stove makers' websites and look at the cut away drawings of the stoves. use this info to see if your modified stove has a chance to burn hard coal.

You of course could burn soft coal (aka bit coal) in your stove. I assume that you don't mind if you void the warrentee?

Thanks,
Glenn

It would be lots easier to burn lump soft coal in that stove but a grate can quickly burn out in a stove like that because of the limited air coming up from underneath cooling the grate and if you plan to keep a constant fire going, getting ashes out can be a pain. Keeping ash from building up under the grate will help it last longer but if you want to burn hard coal you really need a properly designed stove.
