Hundisburg zigzag furnace: Chamber openings walled up during the firing process (right)

A zigzag furnace is a kiln for burning brick walls and roof tiles . It was introduced at the beginning of the 20th century and was especially used in smaller brickworks or for smaller batches. The firing channel has a "zigzag" shape, which has the advantage that in small compartments and in confined spaces you can use the advantages of the ring furnace , which is usually used , as the separation of the compartments by means of solid walls enables each chamber to be appropriately loaded .

The furnace has lower construction costs than the classic ring furnace and is usually placed in the ground. It has an upper transverse smoke outlet to which the channels leading from the combustion duct lead. The brick insert is covered with a flat layer and over it with a roller layer. In the latter, above every heating shaft that has the openings required for the fuel feed, is left free and specially constructed heating boxes with lids are placed on top. The joints in the ceiling are covered with clay and a 10 cm high layer of earth or sand is spread over the whole.

An operational zigzag furnace can be viewed in the Hundisburg brickworks .
