Various dust-like substances are referred to as extinguishers .

  • In mining, it describes fine coal dust (also Lesche , Kohllösche or the matted cabbage ).
  • In metal processing , the term is used for fine powder that occurs in blacksmiths or locksmiths , which is produced when the hammer is blown (hammer blow powder ) and other pulverized iron is mixed with ash and coal dust.
  • In the coal industry (here also Stübbe , Stibbe or Stippe , Gestübe ), the word denotes the disintegrated coal coal ( syn . Coal pieces, coal small, coal grit ), and coal dust, as well as charred parts of the kiln cover of previous coal fires. The extinguisher usually also contains wood tar residues and small pieces of wood, it is black to dark gray. This is mixed with earth and moistened with water, used to cover the charcoal pile or added to the so-called Stübbewall . It also serves to suffocate the embers after pulling the coals out of the kiln. The pieces of charcoal contained in the extinguisher are used in the historical geography of the vegetation reconstruction for the creation of tree species spectra.
  • Extinguishing is the term used to describe the combustion residue from coal , which collects in the smoke chamber of steam locomotives and has to be removed at regular intervals - usually after the end of a working day. Numerous (partly still glowing) ash particles, soot and dust (collective term: fly ash ) collect on the floor of the smoke chamber. To avoid uncontrolled fires and flying sparks, the extinguisher must be extinguished at regular intervals. Due to the high sulfur content, the damp fire extinguishers are extremely aggressive. To protect the steel floor of the smoke chamber, it is therefore cemented .
