Abstract
A housing that can be provided on the inside with a lining, made of an open-pore material and preferably covering at least two sides of the housing, for the reduction of internal explosion pressure. In addition, or alternatively, a molded body made of the open-pore material, in particular a bonded fiber material, can be arranged in the housing. Methods are used to provide an assembly of an open-pore material and a flameproof body in order to create an assembly that has a higher temperature class and/or a higher flameproofing class than those for which the flameproof body is designed.
Claims10
An explosion-protected housing comprising:
- a plurality of walls that enclose an inner space, at least one wall of the plurality of walls comprises:
- an inner side covered with a material, the material being open-pore, bulk, particulate;
- and
- an opening;
- a container within the inner space, the container being gas permeable, wherein the container contains an amount of the material that is less than a maximum amount of the material that the container is configured to contain;
- and
- a gas permeable flameproof body arranged in the opening, wherein:
- the material is arranged inwardly relative to the gas permeable flameproof body,
- the material is configured to at least one of dampen an explosion without arresting flames from the explosion or cool gases from the explosion without arresting the flames from the explosion, and
- the gas permeable flameproof body is configured to arrest the flames from the explosion.
