Abstract:
1. Burner ( 1 ), suitable to generate a flame comprising a cylindrical body ( 3 ) defining a first axis (X) and an extremity, provided with at least one first axial internal conduit for the passage of fuel and at least one second axial internal conduit for the passage of comburent and a head ( 2 ), fixed in a coaxial position at the extremity of the cylindrical body ( 3 ), having an external surface substantially orthogonal to the first axis (X) and provided with first through holes ( 4 ′) which allow communication of the at least one first axial internal conduit with the outside environment and second through holes ( 4 ″) which allow communication of the at least one second axial internal conduit with the outside environment, each of the first and second through holes ( 4 ′, 4 ″) defining a respective second axis (A), being arranged along concentric circles having their respective centres substantially on the first axis (X), at predetermined reciprocal angular distance (δ), each of the second axes (A) being skewed with respect to said first axis (X) whereby it forms first angles (α′, α″) greater than zero with respect to the first axis (X) and it intersects a plane, passing through the first axis (X) and through the point defined by the intersection of the axis (A) itself with the external surface of the head ( 2 ), at second angles (β′, β″) characterised in that the first ( 4 ′) and second ( 4 ″) through holes are grouped in at least two groups ( 5 ), reciprocally separated by circular sectors of predetermined angle (γ), without holes, and wherein the angle (γ) is greater than the reciprocal angular distance (δ).
