  • How Chimneys Work Wood Burning Stoves Forum At Permies

    But coal stoves are very draft-sensitive because of how the coal burns. Unlike wood that burns from either the top down, or bottom up if the stove has grates, coal burns from the bottom up. In fact, the fire will go out with anthracite coal if air goes over the fire. It has to be drawn up through the coal bed.
