Multiflame burner with flame

Abstract

A multiflame burner with burner nozzles which can be loaded with fuel gas, particularly for thermal material processing methods, in which at least one of the burner nozzles is provided with at least one auxiliary nozzle opening for generating an auxiliary flame arranged laterally to a main nozzle arrangement for generating a working flame and in the direction of at least one adjacent burner nozzle.

1 . A multiflame burner comprising burner nozzles that can be supplied with combustible gas, wherein the multiflame burner is constituted as a manual burner or machine burner for operation with acetylene as a combustible gas, and wherein at least one of the burner nozzles is provided with at least one secondary nozzle opening for generating a secondary flame said secondary nozzle opening being disposed at the side of a main nozzle arrangement for generating a working flame, the orientation of said secondary flame having a directional component in the direction of an adjacent burner nozzle, characterised in that at least one of the burner nozzles is provided with two or more secondary nozzle openings on at least one side of the main nozzle arrangement. 
     
     
         2 . The multiflame burner according to  claim 1 , characterised in that at least one secondary nozzle opening and/or at least one nozzle channel associated with the secondary nozzle opening is disposed at an angle to the main nozzle arrangement and/or a nozzle channel associated with the main nozzle arrangement. 
     
     
         3 . The multiflame burner according to  claim 1 , characterised in that at least one of the burner nozzles is provided with secondary nozzle openings for generating secondary flames in the direction of at least two adjacent burner nozzles. 
     
     
         4 . (canceled) 
     
     
         5 . The multiflame burner according to  claim 1 , characterised in that at least one of the burner nozzles is provided with a plurality of linearly disposed secondary nozzle openings. 
     
     
         6 . The multiflame burner according to  claim 1 , characterised in that at least one of the burner nozzles is equipped for the ignition of an adjacent burner nozzle by means of at least one secondary flame. 
     
     
         7 . (canceled) 
     
     
         8 . The multiflame burner according to  claim 1 , which is set up for the ignition of at least one burner nozzle by means selected from the group consisting of a manual ignition device, a spark plug and a piezo igniter. 
     
     
         9 . A burner nozzle for multiflame burners which is supplied with combustible gas, characterised in that at least one secondary nozzle opening for generating a secondary flame said secondary nozzle opening being disposed at the side of a main nozzle arrangement for generating a working flame, the orientation of the secondary flame having a directional component in the direction of an adjacent burner nozzle. 
     
     
         10 . A thermal material processing method, in which a multiflame burner is used, wherein at least one burner nozzle is ignited by means of a secondary flame of an adjacent burner nozzle. 
     
     
         11 . The thermal material processing method according to  claim 10 , further comprising a step selected from the group consisting of flame brazing, fusion bonding, flame blasting, preheating, postheating, soaking, drying and thermoforming. 
     
     
         12 . The multiflame burner according to  claim 1 , which is used for thermal material processing methods. 
     
     
         13 . The multiflame burner according to  claim 9 , which is used for thermal material processing methods.
