Hello Wyclodbuster, welcome to the forum.
Charlie is right, your coal in Wyoming will not burn in most of the anthracite stokers..
EFM is testing a new burner for their 520 model, but won't be able to market it this year.. they are months behind in current, allready sold production. As are all coal stove/boiler/furnace makers..
I have a boiler using an antique [1930's, maybe 1940's] Iron Fireman under feed stoker.. this is probably very much like your Wards feeder..
Please post a few photos of your boiler, the feeder and especially the firedbox. Show us the burnt out sections.. Maybe someone has some parts.. not much of a chance, but worth a try..
Is your boiler still OK, just the burn pot for the feeder/stoker shot??
Since this is Bituminous related, I'm moving this thread to the Bituminous forum..
