1 - 11 . (canceled) 
   
   
       12 . A burner for a turbo machine comprising a flame chamber ( 4 ) including a wall section; a swirl generator ( 12 ) for applying a swirl to an air stream; a baffle plate ( 30 ;  58 ;  60 ;  62 ) for guidance of the air stream in said flame chamber ( 4 ); said baffle plate ( 30 ,  58 ,  60 ) comprising a mounting section; and a plurality of spacers for mounting said baffle plate with said mounting section on said wall section of said flame chamber. 
   
   
       13 . The burner according to  claim 12 , wherein said spacers comprise one of elevations ( 48 ) in said mounting section ( 32 ) of said baffle plate ( 30 ;  58 ;  60 ;  62 ) and elevations in said wall section ( 22 ) of said flame chamber ( 4 ). 
   
   
       14 . The burner according to  claim 12 , wherein said baffle plate further comprises a flow guidance edge ( 34 ) for guiding of an air stream, said mounting section ( 32 ) facing away from said flow guidance edge ( 34 ) for mounting the baffle plate ( 30 ;  58 ;  60 ;  62 ) on said wall section ( 22 ) of said flame chamber ( 4 ) of said burner ( 2 ); and said spacers being formed by a plurality of elevations ( 48 ) at said mounting section ( 32 ). 
   
   
       15 . The burner according to  claim 14 , wherein said baffle further comprises a mounting edge ( 54 ) and said elevations ( 48 ) extend from said mounting edge ( 54 ) in said direction of said flow guidance edge ( 34 ). 
   
   
       16 . The burner according to  claim 15 , wherein said baffle further comprises a planar flow guidance section ( 56 ) and wherein said elevations ( 48 ) taper out in the direction of said flow guidance edge ( 34 ) and develop into said planar flow guidance section ( 56 ). 
   
   
       17 . The burner according to  claim 14 , wherein said elevations ( 48 ) are formed as corrugations having wave crests ( 50   a ,  50   b ,  50   c , . . . ) and wave troughs ( 52   a ,  52   b ,  53   c , . . . ). 
   
   
       18 . The burner according to  claim 17 , wherein said wave crests ( 50   a ,  50   b ,  50   c , . . . ) and wave troughs ( 52   a ,  52   b ,  52   c , . . . ) each have a uniform geometry and are arranged uniformly on said mounting section ( 32 ). 
   
   
       19 . The burner according to  claim 16 , wherein said elevations ( 48 ) are constructed as steps in the form of a square-wave curve. 
   
   
       20 . The burner according to  claim 15 , wherein said baffle plate ( 30 ;  58 ;  60 ;  62 ) is a trapezoidal material strip ( 38 ) having one short longitudinal side ( 40 ) and one long longitudinal side ( 42 ) which forms a conical baffle plate ring in said deformed state. 
   
   
       21 . The burner according to  claim 20 , wherein said flow guidance edge ( 34 ) is arranged on said short longitudinal side ( 40 ), and said mounting edge ( 54 ) is arranged on said long longitudinal side ( 42 ). 
   
   
       22 . A turbo machine comprising a burner according to  claim 12 .
