Processing for #2 begins: February 11. As of March 2 (about 6 weeks total), awaiting results. If it's 6-8 weeks from processing time, I still have weeks to go. My own test took about 3 weeks from activation to completion, but that was a couple of years ago, so maybe there is a bigger backlog right now. Be the first to rate this.
Undo. kframe19. Yes, those kinds of fireplaces generally burned coal-depending on where you are they may well have burned lignite, which is a sort of in between peat and bituminous coal. The solid panels are a nice touch to have, still. Many times they've simply disappeared.
Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler. Burning in suspension, the coal/air mixture provides the most complete combustion and maximum heat possible.
