Burner arrangement

Abstract

A burner arrangement includes a carrier and at least two burners which are mounted on the carrier in a flow direction Each burner includes a cylindrical housing having a lance which is arranged centrally therein and having a fuel duct and which is supported on the housing via swirl blades. An attachment is arranged on the side leading to a combustion chamber At least one fuel nozzle is disposed in the attachment and is connected to the fuel duct. The at least two fuel nozzles of the at least two burners have a different functional characteristic and/or spray form, and the at least two fuel nozzles of the at least two burners with a different functional characteristic and/or spray form include at least one full jet nozzle and at least one pressure swirl nozzle.

         11 . A burner arrangement, comprising:
 a carrier,   at least two burners which are mounted on the carrier in a flow direction,   wherein each burner comprises:
 a cylindrical housing having a lance which is arranged centrally therein and having a fuel duct and which is supported on the housing via swirl blades, 
 wherein an attachment is arranged on the side leading to a combustion chamber, 
 wherein at least one fuel nozzle is disposed in the attachment and is connected to the fuel duct, 
   wherein the at least two fuel nozzles of the at least two burners have a different functional characteristic and/or spray form.   
     
     
         12 . The burner arrangement as claimed in  claim 11 , wherein for each of the burners, the at least one fuel nozzle is arranged downstream of the swirl blades. 
     
     
         13 . The burner arrangement as claimed in  claim 11 ,
 wherein the fuel nozzles with a different functional characteristic differ from one another at least in a nozzle size or a jet angle or liquid distribution or an atomization characteristic.   
     
     
         14 . The burner arrangement as claimed in  claim 13 ,
 wherein, in the case of a different atomization characteristic of the fuel nozzles, at least the drop size distributions differ from one another.   
     
     
         15 . The burner arrangement as claimed in  claim 11 ,
 wherein the fuel nozzles with a different spray form form a full jet, or a hollow conical jet, or a full conical jet or a flat jet.   
     
     
         16 . The burner arrangement as claimed in  claim 11 ,
 wherein the fuel nozzles are oil nozzles.   
     
     
         17 . The burner arrangement as claimed in  claim 11 ,
 wherein an even number of burners which are mounted in the form of a ring on the carrier is provided.   
     
     
         18 . The burner arrangement as claimed in  claim 17 ,
 wherein eight or ten or twelve burners are provided.   
     
     
         19 . The burner arrangement as claimed in  claim 17 ,
 wherein at least four burners are provided, all the burners opposite one another having fuel nozzles with the same functional characteristic and spray form.   
     
     
         20 . The burner arrangement as claimed in  claim 17 ,
 wherein at least four burners are provided, at least two burners opposite one another having fuel nozzles which have a different functional characteristic and/or spray form.   
     
     
         21 . The burner arrangement as claimed in  claim 11 ,
 wherein an odd number of burners is provided.   
     
     
         22 . The burner arrangement as claimed in  claim 11 , wherein the at least two fuel nozzles of the at least two burners with a different functional characteristic and/or spray form comprise at least one full jet nozzle and at least one pressure swirl nozzle.
