Abstract

Bei einem Gasbrenner für einen Heizkessel mit wenigstens einem Brennerrohr(1) mit Flammenöffnungen(7), in dessen Mündung(5) Primärluft und durch eine in die Mündung(5) ragende Gasdüse(4) Brenngas eintritt, soll der Primärluftanteil bei Gasdruckänderungen infolge veränderter Gasbeschaffenheit weitgehend unbeeinflußt bleiben. Die Gasdüse(4) weist innerhalb des Brennerrohrs(1) entweder nur wenigstens eine zur Längsachse(A) des Brennerrohrs(1) radiale Gasöffnung(16) auf, wobei über ein Gebläse(12) dem Brennerrohr(1) die Primärluft zuführbar ist, oder - bei Ausbildung als atmosphärischer Gasbrenner - zur Längsachse(A) des Brennerrohrs(1) radiale Gasöffnungen(16) sowie ein verschiebliches Düsenteil(21) auf, das eine zur Längsachse(A) des Brennerrohrs(1) axiale Gasöffnung(23) bildet und die radialen Gasöffnungen(16) bei zunehmendem Gasdruck öffnet und bei niedrigem Gasdruck schließt.

Figure 00000001
In a gas burner for a boiler with at least one burner tube (1) with flame openings (7), in the mouth (5) of which primary air and fuel gas (4) protruding into the mouth (5), the proportion of primary air should change as a result of changes in gas pressure when the gas pressure changes Gas quality remain largely unaffected. The gas nozzle (4) has either only at least one gas opening (16) radial to the longitudinal axis (A) of the burner tube (1) within the burner tube (1), the primary air being able to be fed to the burner tube (1) via a fan (12), or - in the case of an atmospheric gas burner - to the longitudinal axis (A) of the burner tube (1) radial gas openings (16) and a displaceable nozzle part (21) which forms an axial gas opening (23) to the longitudinal axis (A) of the burner tube (1) and the radial gas openings (16) open with increasing gas pressure and close with low gas pressure.
