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.

When you burn coal to generate electricity (or even to heat your home) the gas going up the chimney contains carbon dioxide, water vapor, nitrogen, nitrous oxides, sulfur oxides, fly ash and mercury.There is also solid waste ash that must be removed afterwards, though some of this can be used in building.ome coal contains sulfur or sulfur compounds. These can be released by burning to produce sulfur dioxide, which reacts with water in the atmosphere to produce sulfurous and sulfuric acids, which are significant components of acid rain.
