Definitions

  • the mutually engaging faces of the casing parts 2, 3 and 4 have corresponding steps and recesses 13 and 14 that engage directly in one another.
  • the engaging faces of the casing parts 1 and 2 have steps 15 and 16 in which two profile rings l7, 18, which are bolted together, seat in engagement partly in one and partly in the other of the two steps 15 and 16.
  • the ring 18 is screwed into the casing ring 2.
  • the profile ring 9 constituting the outlet nozzle of the burner engages on the one side in a step of an interposed ring 19 that seats in a step 20 of the casing ring 4 and is screwed onto this, and on the other side in the aperture of the casing ring 5. In this way the casing rings 1 to 5 are centred in relationto one another.
