Stoker Coal...like the name means...sized for burning in a stoker-fed unit w/ forced draft in a small compact burn-pot w/ tuyers. Will not burn well when in a big mass over a large grate...may even fall through the grate because of it's smaller size.

Others will soon weigh in on this with more. :)

Stick with your lump coal, stoker won't burn in your boiler.

stoker will likely be worse, the bigger the lump the cleaner and smoother the burn with bit coal. Some bit coals make more smoke and soot than others; try a different supplier of lump bituminous coal, maybe you will find better stuff. you could try building a hot fire (leave the ashpan open with a bed of red coals) to blow/burn the soot out every day or every other day, then you won't have to clean it as much. Either way, a 6" stack is too small. if you had an 8" or larger stack size cleaning wouldn't be an issue, the soot would periodically fall off and never build up to be a problem. 6" just clogs right up with some coals.
