Coal (3-7 kg/h) was burned at atmospheric pressure at a temperature of 750-900 °C. All samples were burned in a fluidized bed. This allowed for the reduction of the combustion temperature to 800-900 °C, the reduction of the combustion chamber dimensions, and the use of inferior quality fuels (contaminated and with lower calorific value).

As well as it metallurgical uses, coal was increasingly used during the Industrial Revolution as a source of power. The heat energy it created was transformed into mechanical energy thanks to the development of the steam engine. Somewhat ironically, the first steam engine, which was developed by Thomas Newcomen in 1712, was made to pump water.
