摘要：
The invention relates to a gas burner comprising:
- an injection holder (2) with a gas injector (2.1);
- a burner body (3) adapted to be arranged at the injection holder (2), the burner body (3) comprising an opening (3.1) for enabling a gas flow from said gas injector (2.1) and a primary air flow in an area above said burner body (3);
- a burner cap (4) adapted to be arranged at the top side of the burner body (3), the burner cap (4) comprising a bottom portion (4.1) and a circumferential surface portion (4.2) protruding downwardly from said bottom portion (4.1), wherein the circumferential surface portion (4.2) comprises a plurality of flame ports (4.3) and said burner body (3) and said burner cap (4) confine a chamber (5) for providing a combustion mixture of gas and primary air;
wherein the burner body (3) comprises a bulge-shaped protrusion (3.5) forming a continuous ridge below the burner cap (4) at least in the area in which the flame ports (4.3) are provided, said bulge-shaped protrusion (3.5) reducing the distance between the burner cap (4) and the burner body (3) in the area of the flame ports (4.3).
- an injection holder (2) with a gas injector (2.1);
- a burner body (3) adapted to be arranged at the injection holder (2), the burner body (3) comprising an opening (3.1) for enabling a gas flow from said gas injector (2.1) and a primary air flow in an area above said burner body (3);
- a burner cap (4) adapted to be arranged at the top side of the burner body (3), the burner cap (4) comprising a bottom portion (4.1) and a circumferential surface portion (4.2) protruding downwardly from said bottom portion (4.1), wherein the circumferential surface portion (4.2) comprises a plurality of flame ports (4.3) and said burner body (3) and said burner cap (4) confine a chamber (5) for providing a combustion mixture of gas and primary air;
wherein the burner body (3) comprises a bulge-shaped protrusion (3.5) forming a continuous ridge below the burner cap (4) at least in the area in which the flame ports (4.3) are provided, said bulge-shaped protrusion (3.5) reducing the distance between the burner cap (4) and the burner body (3) in the area of the flame ports (4.3).
