Abstract

Die Erfindung betrifft eine Brenneranordnung mit einem Brennerkörper (3), der eine Innenoberfläche (4) und eine Außenoberfläche (5) sowie ein Muster aus Öffnungen (6) zum Durchtritt eines Luft-Brenngas-Gemisches aufweist, und einer lonisationselektrode (7) mit einer Elektrodenlänge (EL), die mit einem Abstand (A) von der Außenoberfläche (5) des Brennerkörpers (3) und im Wesentlichen parallel zu dieser verläuft, wobei ein Verteilbleich (8) vorhanden ist, welches das Muster aus Öffnungen (6) im Bereich (10) der lonisationselektrode (7) verändert, indem es einen Teil der Öffnungen (6) zumindest teilweise abdeckt. Die Erfindung erlaubt es, mit einfachen Mitteln die Anwendbarkeit und/oder Genauigkeit eines lonisationsmesssystems zu erweitern und damit ausgestattete Heizgeräte in einem breiten Leistungsbereich zu regeln.The invention relates to a burner arrangement with a burner body (3) which has an inner surface (4) and an outer surface (5) and a pattern of openings (6) for the passage of an air-fuel gas mixture, and an ionization electrode (7) with a Electrode length (EL) spaced a distance (A) from and substantially parallel to the outer surface (5) of the torch body (3), there being a diffuser (8) defining the pattern of openings (6) in the area (10) of the ionization electrode (7) changes in that it at least partially covers part of the openings (6). The invention makes it possible to expand the applicability and/or accuracy of an ionization measurement system with simple means and to control heating devices equipped with it over a wide power range.
