you can do it, but I don't think it's a normal way to describe coal. I could be wrong as I don't work in an industry where stoking is a regular behaviour
Well, I'm not talking about some special type of coal, I'm just trying to figure out how "stoking" is understood if used with a noun. coal is just an example word. I actually doubt that "stoking coal" is understood as "the process of stoking coal", while I need something that would mean "coal for stoking furnace".
@MattE.Эллен OK, how would you understand the expression "stoking wood"? "Wood used for stoking something" or "the process of stoking the wood itself" (this sounds as non-sense to me)?
