Cannon furnace

from Wikipedia, the free encyclopedia

A cannon furnace is a small cast iron cylindrical furnace . The vent for the flue gas is usually attached to the side on the upper part, less often vertically. Due to their construction, such ovens are mostly designed for burning coal , but other solid materials such as wood or peat can also be burned. In this cylinder is the combustion chamber for the coal with the ash grate and the ash box underneath, which are closed with appropriate doors during the burning process.

history

Similar large-scale cast iron stoves existed as early as the 18th century. It was named after the cylindrical shape and the resulting resemblance to cannons . These ovens were particularly widespread in Central Europe from the second half of the 19th century. The heating output was usually only sufficient for a single room, so different sizes were offered accordingly. In addition to its function as a heat source, the cannon furnace also served as a decorative element. In the course of time, modified forms of this furnace emerged, which are also incorrectly referred to as the cannon furnace.

Orders from Count Palatine Karl IV. From 1772 also served to prevent a fire in connection with domestic fireplaces. According to the simultaneous building regulations, no more wooden chimneys were allowed to be erected and no more wooden hoses were allowed to be installed, which had to lead the smoke from the fireplace to the fireplace , just as it was forbidden to lead stove pipes out of the window.

environmental Protection

Due to the stricter regulations for air pollution control that are now in force in many European countries, such as For example, in Germany the regulation on small and medium-sized combustion systems , such furnaces are generally no longer permitted and can therefore hardly be found on the market. Strictly speaking, old cannon furnaces may no longer be used; however, this does not make sense anyway, since they are usually not sufficient to heat today's living spaces due to their small size. The risk of fire or the release of toxic smoke gases from damaged or improperly maintained specimens should not be underestimated.
