  • Steam generated in the steam generator 137 therefore flows in the circulation system from the base part 13 into the upper part 15 and through the opening 124 from above into the working space 12. This transport of the steam through the circulation system can be assisted by the fan 141.
  • the arrangement described can also be operated without the assistance of the fan 141 in a manner which makes it possible to clean the catalyst surfaces 143 of deposits such as lime, organic compounds such as hydrocarbons, or lint and thus at least partially regenerate the catalyst.
  • steam from the steam generator 137 passes as directly as possible to the catalyst surfaces.
  • the arrangement can thus both in a normal operating mode operate in which the work space is preferably fed with steam from above, as well as in a cleaning mode in which the steam is preferably used for the purification of the catalysts.
  • the steam generator can be placed in the top or near the top so that the generated steam can enter directly into the workspace.
  • the output of the steam generator can also be connected via a separate steam line which runs separately from the air circulation duct to the ceiling area of the work space. It is also possible to provide the steam generator with an additional output, which opens, for example through the bottom plate in the work space.
