Abstract: The present invention relates to a burner assembly for cooking equipments that has been designed to provide significant improvement in thermal efficiency of the burner and making easier the cleaning process by the user. The burner assembly comprises a base (2) upon which a spreading cover (3) rests, and wherein the coupling of the spreading cover (3) on the base (2) originates one internal chamber of expansion (4) of air-fuel mixture which is released through porticos existing under the perimeter edge of the spreading cover (3), and wherein the base (2) comprises in its internal region at least one feeding orifice (22); the spreading cover (3) comprises at least one perimeter ring (31) cooperating with the base (2) and at least one disc (32) cooperating with the perimeter ring (31) and the burner assembly (1) comprises at least one internal chamber of mixture (4) cooperating with the porticos of the spreading cover (3).

Abstract: The present invention refers to a stove gas burner provided with a base having a smooth geometry, as well as a removable cap, also with a smooth geometry, which is able to deliver increased efficiency in the food heating process, thus reducing preparation time thereof and facilitating the cleaning of said burner by the user. Thus, a set of base and spreading cap of a stove burner (1) is described, the base (200) being able to support the cap (4) in a fitting cavity (5), the cap (4) being provided with primary gantries (15) and secondary gantries (25) both flame guiders located in the outmost periphery (300) of the cap (4), the primary gantries (15) and secondary gantries (25) being radially projected from the base center (200).
