| 1. A burner comprising:
a tubular body comprising a first half shell and a second half shell coupled one to one other; and
a venturi tube coupled to a first end of the tubular body,
wherein the first and the second half shells each comprise a substantially flat central portion extending longitudinally and
first and second lateral portions extending angularly therefrom, the first and the second half shells being coupled to one
another by coupling the first and the second lateral portions to one another,
wherein a plurality of longitudinal depressions project inwardly from the flat central portions of the first and the second
shells to direct an air and gas mixture within the tubular body along longitudinal channels defined by the inward projecting
longitudinal depressions,
wherein the longitudinal depressions extend substantially parallel to a longitudinal axis along a portion of the tubular body
and converge inwardly to form a funnel shape in the proximity of the venturi tube, and
wherein the first half shell comprises a plurality of opening rows extending longitudinally to enable the air and gas mixture
to egress the openings in the rows to feed a flame, one of the opening rows comprising a plurality of openings having a smaller
size than the openings in the other opening rows such to provide a pilot burner.
