Abstract
A burner for gas cookers that includes a body provided with at least one aperture that defines at least one concentric flame crown and a base fitted to a cooking hob. The burner has an interchangeable circumferential ring that is fitted to the body by a mechanical fixture, which increases diameter of the body in proximity of the base. The ring curves toward the cooking hob like an annular skirt to define a passage for use with burners which draw primary air from above the cooking hob.
