What if I burned a small amount of coal in my wood stove?

Question

What's the possibility of overheating my wood stove with a few pieces of coal every couple of hours for more heat? My stove has a catalytic converter and nice chimney, so backfumes shouldn't be an issue.

Answer 1

If the wood stove is made of iron,do not try it with coal. Coal produces high heat that can melt down iron.

Answer 2

Coal will make an excellent fuel for a wood burner stove. It will burn more slowly and when banked, will give good heat much longer than wood. Blacksmiths do use coal for high temperatures, but they also use a blast of air which will not be the case in a wood burner. Cast iron in also used in the grating of some power boilers. Residential fireplaces have used cast iron grates for coal for hundreds of years. Beside, your burner should already have a firebrick liner in the bottom so there is extra protection there. Start with wood, heat with coal.
