Abstract
A tubular burner has a body comprising a diffuser portion provided with openings for discharging a mixture of air and fuel fed to the body through a Venturi tube arranged inside the body. The body has a cross section shaped in such a way that a distance between an outer wall of the Venturi tube and an inner wall of the body, when measured in a radial direction of the Venturi tube, has a first value substantially constant over a first portion of a perimeter of the Venturi tube and a second value greater than the first value over a second portion of the perimeter. A chamber is defined in the second portion between the outer wall of the Venturi tube and the inner wall of the body. The mixture passes through the chamber before being discharged through the openings. The chamber is delimited at a bottom thereof by laminar flow generating means for generating a substantially laminar flow of the mixture.
