Triple flame section burner
First Claim
1. A burner having at least two concentric flame sections, the burner comprising:
- a burner head, which contains the at least two concentric flame sections, wherein each section comprises an intermediate segment, an outer segment and a main channel located between the outer segment and the intermediate segment, wherein each segment comprises respective combustion ports, the respective combustion ports of the outer segment comprising a helicoid structure, which defines an inclination to produce inclined flames, the combustion ports of the intermediate segment comprising a straight structure, wherein each combustion port of the intermediate segment comprises a labyrinth;
a flame moving chamber disposed between each flame section, wherein the flame sections are covered by a lid;
at least one Venturi duct in each flame section with an exit to the main channel; and
at least one exit disposed on a lower surface of the burner head to aerate the burner head, wherein the combustion ports comprise a main combustion port having a cross-sectional area defined by a plurality of steps, the plurality of steps defining a slope sequence arranged to control a velocity of a combustion mixture flowing there through, the slope sequence defined by the plurality of steps comprising a first slope in a range from 10°
to 30°
, a second slope in a range from 0°
to 15°
, a third slope in a range from 30°
to 80° and
a fourth slope in a range from 0°
to 15°
, wherein the combustion ports of the central burner head define an inclination, wherein the inclination of the burner head and the inclination of the central burner are arranged in a clockwise direction or in a counter-clockwise direction, and the inclination directions in both burners is the same or opposite with respect to one another.

Abstract
The present invention relates to the field of burners, particularly in burners intended for household use, such as stoves. A three ring burner is described, which produces longer and more inclined flames through which a more efficient heating is accomplished; combustion ports in the rings with straight or helicoid arrangements; where the inner ring can function in conjunction with or independently from the other two flame rings, thus controlling the heating intensity and the flame by means of controlling the velocity of the gas-air current; as main parts comprising; a burner head, which contains three concentric flame rings, one inner ring, one intermediate ring and one outer ring, each flame ring containing combustion ports, the collection of combustion ports are helicoid both in their inner ring as well as the outer ring, two lids on the burner head, one inner and the other outer; one cover for the burners which forms the surface of the heating apparatus; Venturi ducts on the lower part of the burner head; a support firmly joined to the surface of the heating apparatus, in this support are lodged Venturi ducts from the burner head; a gas distributor lodged in the lower part of the support, where the gas distributor has three gas exits, two laterals and one central.
