Abstract

A burner barrel includes a concentric multi-tubular structure, formed by pipes and at the end downstream the burner barrel is provided a burner tip in which various nozzles to inject fuel and primary air are perforated. The burner tip includes at least one series of nozzles intended to inject an external air flow; a second series of nozzles intended to inject tangential air flow; and a third series of apertures intended to inject the fuel and transport air. The ends downstream of the first and second burner pipes are joined and define a continuous external annular surface of the burner tip. The nozzles are arranged within an inscribed area, being the dimension of the nozzles limited by a rate between the open area A of the nozzles and the complementary closed area A.
