Abstract

A burner comprises a substantially tubular body (1), closed at a first end (2) by a first closure element (3) and provided with a second end (4) of a second closure element (5) provided with an inlet (5a) through which a mixture of fuel and air is delivered into said body (1), said body (1) being provided on a side surface with openings (6, 7) for the exit and subsequent combustion of said mixture, with said second closure element (5) there is associated a channelling element (8; 11) that is suitable for varying the passage section of said flow of mixture and/or dividing said flow of mixture into a plurality of flows of mixture.
