Anthracite is too valuable to burn in household furnaces. The stuff we get here is better than bituminous but has a lot of clay content.
I am from the anthracite region of Pennsylvania. Anthracite is the ideal fuel for home and commercial heating. It burns slowly and cleanly. No smell. No soot. Bituminous coal burns fast and produces a lot of heat which makes it ideal for power plants and steam locomotives. But it stinks up the neighborhood if burned in a coal stove.
