You have more than heat going up your chimney. Or did you invent a way to burn coal without using the chemistry of combustion? Burning anything gives heat, CO2, CO and other byproducts. The other varies a lot depending on the fuel. Anthracite produces a lot of CO2. More detail is in the following thread:
By that I meant I am not pumping black smoke out of my chimney like last year when I burned soft coal. There isnt the smell of black death outside when I burn the hard coal versus the soft.
However, I am on board with others. When they stop us from burning coal, i will burn everything else that burns. That includes tires, old plastic toys, insulation, treated lumber, and what ever else I have that will burn. That should be a lot better on the environment then CO2.
What the hell do I know. I am just a regular dude who works behind a razor wire fence for 8 hours a day and makes sure his family is well taken care of. I dont care to know, nor do I have much interest in knowing, the chemistry in burning coal. Want to talk about the best way to catch a large mouth or lifting weights, I am all in.
I do know the neighbors much prefer hard coal over wood and soft coal. No smell, no mess.
