a crenellated wall along the length of the periphery of the burner, the wall comprising

a plurality of first segments with a first thickness and at least a second segment with a second thickness greater than the first thickness, the second segment allows that a cover lid be seated and placed over the crenellated wall thereby covering the mixing tube, the pre-mixture chamber, the inner crown and the mixing chamber, and

a plurality of main portholes which are constant for a determined length of said main portholes from the inside towards the outside of the crenellated wall, and near to the outer part of the crenellated wall, the height of the porthole is decreased by virtue of an α

angle;

at least one secondary porthole with a smaller size than that of the main portholes, wherein the at least one secondary porthole has a change of direction in such a way that the height of the at least one secondary porthole decreases from the inside towards the outside of the crenellated wall according to a β

angle until the height of the porthole achieves a constant height near the outer part of the wall; and

at least two tertiary portholes per each first and second segment in a half cane shape, the half cane diameter is equal to the width and depth of said tertiary porthole, wherein said tertiary portholes are a smaller size than the at least one secondary porthole.

2. The burner according to claim 1, wherein the burner comprises some feet which lend the burner support over the face of a cover lid of a stove, providing a space between said burner and said face, thus allowing for free air flow.

3. The burner according to claim 1, wherein the inner crown has a height which is greater than the pre-mixture chamber and the mixing chamber, decreasing the distance between the base of the pre-mixture chamber and an inner face of the cover lid, thus the inner crown doses a mass flow of the mixture towards the mixing chamber.

4. The burner according to claim 1, wherein the segments are separated from each other by a main porthole or a secondary porthole.

5. The burner according to claim 1, wherein the first thickness varies between approximately 5 mm to 8 mm and wherein a second thickness varies between approximately 8 mm to 10 mm, allowing that said second thickness protrudes in relation to the remainder of the crenellated wall, in such a way that the cover lid is adjusted over the crenellated wall and has a set according to the crenellated wall.

6. The burner according to claim 1, wherein the diameter of the half cane of the tertiary portholes varies between approximately 0.8 mm to 3 mm and wherein the half cane has a cross cut section selected from amongst straight, curved, squared, rectangular or oval.

7. The burner according to claim 1, wherein the β

angle varies between 45°

to 85°

, wherein the height of the constant part of the secondary porthole is between approximately 1 mm to 2 mm in height and wherein the length of the constant part of the secondary porthole is not greater than 75% of the total length of said secondary porthole.

8. The burner according to claim 7, wherein the flow of the mixture which passes through an outer part of the secondary porthole collapses against a bezel of the cover lid, anchoring the flame dart provided by the secondary porthole upon creating a turbulence area under said bezel.

9. The burner according to claim 1, wherein the constant length of the main porthole is approximately 50% to 75% of the total length of the main porthole, wherein α

varies between 45°

to 85°

, where a mass flow which travels through said main porthole loses energy.

10. The burner according to claim 9, wherein a mass flow which passes through an outer part of the secondary porthole collapses against a bezel of the cover lid, anchoring the flame dart provided by the main porthole upon creating a turbulence area under said bezel.

11. The burner according to claim 1, wherein the burner under the portholes set on the crenellated wall, an air ring is placed, which drags the secondary air emanating from the lower part of the burner.

19. A stove, kitchen or cooking surface comprising the burner of any of the prior claims, wherein the stove, kitchen or cooking surface additionally comprise a grill set over the burner, and wherein the at least one secondary porthole emits a flame dart which has a greater size than that of a flame dart from the main porthole, in such a way that the flame dart of the secondary port hole does not collapse against the grill.

20. The stove, kitchen or cooking surface according to claim 19, wherein the design of the grill determines the number of secondary portholes found in the crenellated wall of the burner.

12. A gas burner comprising:

a section for mixing the combustible gas with air;

a cover lid closing the mixing section; and

a crenellated wall comprising

a plurality of first segments with a first thickness and at least a second segment with a second thickness greater than the first thickness, the second segment allows the cover lid to be sitted and placed over the wall, and
