Burner Arrangement

Abstract

The invention relates to a burner arrangement comprising a burner plate ( 1 ) having a multiplicity of apertures ( 2 ) and a monitoring device for monitoring the formation of a combustion zone ( 3 ) extending from the burner plate ( 1 ), wherein the monitoring device comprises a cathode ( 5 ) provided on a flame-side top ( 4 ) of the burner plate ( 1 ) and an anode ( 7 ) arranged in the region of the combustion zone ( 3 ). To improve the thermal stability and thus the durability, provision is made according to the invention for the burner plate ( 1 ) to be made of a non-metallic material and for the cathode ( 5 ) to be arranged as a separately designed component in the region of the top ( 4 ) of the burner plate ( 1 ).

1 . Burner arrangement with a burner plate ( 1 ) having a plurality of breakthroughs ( 2 ) and a monitoring unit to monitor the formation of a combustion zone ( 3 ) extending from the burner plate ( 1 ),
 wherein the monitoring unit comprises a cathode ( 5 ) on a top side ( 4 ) of the burner plate ( 1 ) pointing towards the combustion zone ( 3 ) and an anode ( 7 ) extending into the area of the combustion zone,   characterized in that   the burner plate ( 1 ) is made of a non-metallic material and the cathode ( 5 ) is located as a separately formed component in the area of the top side ( 4 ) of the burner plate ( 1 ).   
     
     
         2 . Burner arrangement as defined in  claim 1 , wherein a volume burner body ( 9 ) with a combustion-enabling, communicating porous space is located opposite the top side ( 4 ). 
     
     
         3 . Burner arrangement as defined in  claim 1 , wherein a slit ( 11 ) of a specified width is provided between the top side ( 4 ) and a bottom side ( 10 ) of the volume burner body ( 9 ). 
     
     
         4 . Burner arrangement as defined in  claim 1 , wherein the volume burner body ( 9 ) and/or the burner plate ( 1 ) is/are made of a ceramic material. 
     
     
         5 . Burner arrangement as defined in  claim 1 , wherein the cathode ( 5 ) is located in the slit ( 11 ). 
     
     
         6 . Burner arrangement as defined in  claim 1 , wherein the cathode ( 5 ) is contained in a recess ( 6 ) opening towards the top side ( 4 ) of the burner plate ( 1 ). 
     
     
         7 . Burner arrangement as defined in  claim 1 , wherein at least some of the breakthroughs ( 2 ) provided in the burner plate ( 1 ) open in the recess ( 6 ). 
     
     
         8 . Burner arrangement as defined in  claim 1 , wherein the cathode ( 5 ) extends from the recess ( 6 ) into a further bottom side ( 8 ) of the burner plate ( 1 ) opposite the top side ( 4 ). 
     
     
         9 . Burner arrangement as defined in  claim 1 , wherein the cathode ( 5 ) is contained in a recess ( 6 ) which opens towards the bottom side ( 10 ) of the volume burner body ( 9 ). 
     
     
         10 . Burner arrangement as defined in  claim 1 , wherein the recess ( 6 ) is formed corresponding to the form of the cathode ( 5 ). 
     
     
         11 . Burner arrangement as defined in  claim 1 , wherein the cathode ( 5 ) is formed from a perforated plate or preferably a spiral or meandering-shaped wire. 
     
     
         12 . Burner arrangement as defined in  claim 1 , wherein the burner arrangement is part of a gas burner.
