The most common stove for heating in the industrial world for almost a century and a half was the coal stove that burned coal. Coal stoves came in all sizes and shapes and different operating principles. Coal burns at a much higher temperature than wood, and coal stoves must be constructed to resist the high heat levels. A coal stove can burn ...
Hot blast allowed the use of anthracite in iron smelting. It also allowed use of lower quality coal because less fuel meant proportionately less sulfur and ash. [11]At the time the process was invented, good coking coal was only available in sufficient quantities in Great Britain and western Germany, [12] so iron furnaces in the US were using charcoal.
A potbelly stove is a cast-iron, coal-burning or wood-burning stove that is cylindrical with a bulge in the middle.

The coal would then be raked by the men into a layer of even thickness and the retort sealed. Gas production would then ensue – and from 8 – 12 hours later, the retort would be opened, and the coal would be either pulled (in the case of "stop-ended" retorts) or pushed (in the case of "through" retorts) out of the retort.

The History of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity.
