Abstract

A burner (15) of premixed type is illustrated, comprising a flame confinement chamber (17) with elongated shape, a spiral motion means (3), adapted to confer a tangential speed component to a previously prepared fuel and comburent mixture flow, entering into said flame confinement chamber (17), a mixture flow deviation means (9), which is placed downstream of said spiral motion means (3) and which is adapted to deviate the mixture flow motion downstream of the spiral motion means (3) in such a manner that a central mixture flow portion is slowed and a peripheral portion thereof is accelerated, and a combustion trigger device (10) positioned downstream of said mixture flow deviation means (9).
