Rumford furnace

As Rumford stove or oven Rüdersdorfer is called a kiln for the industrial production of lime, are available in the separate combustion chambers for lime and fuel.

Technology

The separation of fuel and lime made ​​it at the beginning of the 19th century possible large amounts of high-quality quick lime for the building industry to produce, since this could not be contaminated by contact with the fuel:

The firebox on the side is completely separate from the actual combustion chamber. A single cross- channel connecting the two slots through which the hot air passes from the combustion chamber into the combustion chamber. Lime is introduced from above into the combustion chamber, the ash from the combustion chamber to fall within a separate shaft, from which they can be removed. Below the firebox of the lime in the combustion chamber is cooled, as the heat from the combustion chamber flows upward. The upper part of the combustion chamber, which is not applied directly to the combustion chamber serves as a preheat space, and is of hollow chambers which are filled with coal dust, isolated from the combustion chamber.

Historical development

The first Rumford oven was built in 1804 Rüdersdorf, which can be seen in the museum park Ruedersdorf even today. The construction of the furnace followed the defaults by Benjamin Thompson, Count Rumford, meanwhile, nicknamed the furnace was known. In the years that followed, the appropriate technology spread throughout Europe.
