Definitions

  • the aim of the invention is to present a burner for low calorific fuels which would ensure sufficient stability of the flame and which would also eliminate undesired critical conditions arising during its operation when disruption of the flame or fire penetration into the burner body occurrs.

Claims (4)

  1. Brenner, bestehend aus einer Zuführungsluftrohrleitung, einer zentralen Brennerrohr (5), aus einer Zuführungsbrennstoffrohrleitung, die an die zentrale Brennerrohr (5) angeschlossen ist, die mit einem Blendstirn (6) auf der Seite der Zuführungsluftrohrleitung (8) beendet ist, wobei der Brenner (1) ein Tragrohr (7) beinhaltet, die auf den erwähnten Blendstirn (6) befestigt ist, und beinhaltet auch einen Brennerkopf (4), der auf der erwähnten Tragrohr (7) auf dem Brennerausgang angeordnet ist, wobei der Brennerkopf (4) mit Düsen (13) versehen ist, die in einem Kreis in der Nähe des Innenumfangs des Brennkopfes (4) angeordnet sind, und die eine primäre Stufe des Brenners (1) bilden, wobei der Brenner (1) weiter einen Verwirbler (2) beinhaltet, der mit seinem Innenumfang (15) auf dem Ausgangsende der zentralen Brennerrohr (5) angeordnet ist, wobei die Oberfläche (16) des Verwirblers (2) eine konische Form hat, die sich in Richtung aussen verbreitet und die Oberfläche (16) ist mit Öffnungen (9) versehen, die im Kreis angeordnet sind, dadurch gekennzeichnet, dass der Brennerkopf (4) auf dem äusseren Umfang mit geneigten Rillen (14) versehen ist, die eine sekundäre Stufe des Brenners (1) bilden.
  2. Brenner nach dem Anspruch 1, dadurch gekennzeichnet, dass die Öffnungen (9) auf dem Verwirbler (2) in drei konzentrischen Kreisreihen verteilt sind.
  3. Brenner nach dem Anspruch 1, dadurch gekennzeichnet, dass die Zuführungsluftrohrleitung (8) auf seiner Wand durch einen Aufschweissstück (11) für Anschliessung eines Manometers oder einer anderen Messeinrichtung versehen ist.
  4. Brenner nach dem Anspruch 1, dadurch gekennzeichnet, dass auf dem freien Ende der Tragrohr (7) Schrauben (12) für Aretation eines beigeschlossenen Atomizers angeordnet sind.
