Abstract: A fuel element for open burning installations, such as a fireplace, containing a shell-like, elongated housing, in which a supply of fuel may be filled and refilled. In addition, at least one flat burner body, such as a flat wick, is arranged in the housing and immersed with its lower part in the fuel supply, while its upper edge is protruding in a height adjustable manner from the top side of the housing. A fireplace suitable for fuel elements of this type contains an exhaust hood in which is positioned a filter in the form of an absorber to purify and regenerate the air rising from the fuel elements, in particular removing suspended particles and eliminating unpleasant odors. The fireplace does not require outside connections.
