Adjustable burner

Abstract

A burner suppliable with a mixture of air and fuel comprises a body of the burner provided with a diffuser in the surface of which openings are made for the exit of said mixture delivered into the body of the burner, and a distributing device inserted inside said body of the burner. The distributing device comprises a regulating element provided with further openings for the transit of the mixture, the regulating element being movable within the body of the burner. The body of the burner can be subdivided into a plurality of sectors, each one of which is independently suppliable by the other sectors.

       59 . The burner according to  claim 57 , wherein said sections of the body and said sections of the distributing element are fixed to a series of radial baffles, that lead away from a central hollow cylindrical support. 
   
   
       60 . The burner according to  claim 59 , wherein said radial baffles are distributed at a substantially constant angular pitch. 
   
   
       61 . The burner according to  claim 59 , wherein each of said radial baffles is provided at its external end with a groove extending in a direction substantially parallel to a longitudinal axis of said hollow cylindrical support. 
   
   
       62 . The burner according to  claim 61 , wherein each of said sections of said body is provided with edges folded towards the inside of the body, said edges being insertable into said grooves. 
   
   
       63 . The burner according to  claim 59 , wherein each radial baffle is provided on both sides, at a certain distance from its external end, with a pair of fins protruding in a substantially perpendicular direction from the baffle and defining between them a corresponding groove. 
   
   
       64 . The burner according to  claim 63 , wherein said fins and said grooves extend in a direction substantially parallel to the longitudinal axis of the hollow cylindrical support. 
   
   
       65 . The burner according to  claim 63 , wherein said grooves are suitable for receiving an end of a respective section of the distributing element. 
   
   
       66 . The burner according to  claim 59 , wherein each of said sectors is defined by a pair of adjacent radial baffles, by a respective section of the body fixed to said pair of radial baffles and by a respective section of the distributing element also fixed to said pair of radial baffles. 
   
   
       67 . The burner according to  claim 59 , wherein said hollow cylindrical support is provided with groups of openings for the transit of said mixture of air and fuel, each group of openings corresponding to one of said sectors of the body. 
   
   
       68 . The burner according to  claim 67 , wherein said openings have the shape of slits a greater side of which extends in a direction parallel to generatrices of the cylindrical support. 
   
   
       69 . The burner according to  claim 67 , wherein inside said cylindrical support there is inserted a regulating element through which said mixture of air and fuel is delivered into said body, said regulating element being provided with openings for the transit of said mixture. 
   
   
       70 . The burner according to  claim 69 , wherein said regulating element comprises a hollow cylindrical body, in the surface of which said openings are made, said hollow cylindrical body being able to rotate in relation to said hollow cylindrical support.
