- a gas burner head (7) placed on the gas burner body (2), enabling transmitting flame to the base of a cooking container through the holes disposed around it, a gas burner cap (8) placed on the gas burner head (7), - a first horizontal nozzle (9) and a second horizontal nozzle (10) placed opposite each other on the gas burner body (2), - a first outer mixing chamber (11) and a second outer mixing chamber (12) provided on the gas burner body (2), - a first Venturi tube (13) enabling transmitting the gas received through the first horizontal nozzle (9) to the first outer mixing chamber (11), and a second Venturi tube (14) enabling transmitting the gas received through the second horizontal nozzle (10) to the second outer mixing chamber (12) ( Figure 2 and Figure 3).
- the gas burner group (1) of the invention comprises, - at least one air inlet port (15) provided on the gas burner body (2) next to the first horizontal nozzle (9), extending to the first Venturi tube (13), and - at least one second air inlet port (16) provided on the gas burner body (2) next to the second horizontal nozzle (10), extending to the second Venturi tube (14).
- the gas burner group (1) by means of which an inner flame crown and an outer flame crown encircling the inner flame crown are generated, enables heating a cooking container placed thereon with higher power.
- the inner flame crown is fed by the gas-air mixture formed in the inner mixing chamber (3) provided in the center of the gas burner body (2), by mixing air with the gas transmitted through the vertical nozzle (4) provided on the base of the inner mixing chamber (3).
- the outer flame crown is fed by the gas-air mixture formed by mixing in the first outer mixing chamber (11) and the second outer mixing chamber (12), the gas transmitted through the first horizontal nozzle (9) and the second horizontal nozzle (10) placed opposite each other in the gas burner body (2), with the air received through the first air inlet port (15) and the second air inlet port (16).
- the air required for burning is continuously provided thanks to feeding the gas-air mixture transmitted to the outer flame crown, separately through the first air inlet port (15) and the second air inlet port (16), thereby enabling performing the burning process effectively.
- emission formation is prevented, likely to occur due to not burning of the gas transmitted through the first horizontal nozzle (9) and the second horizontal nozzle (10).
- the gas burner group (1) comprises at least one first air inlet duct (17) extending outwards from the first air inlet port (15), in parallel to the first horizontal nozzle (9), and at least one second air inlet duct (18) extending outwards from the second air inlet port (16), in parallel to the second horizontal nozzle (10).
