Premix burner, comprising:
- an air inlet tube of length L;
- and
- a single specific gas injection system;
- wherein said gas injection system comprises:
- an upstream gas injector,
- a mixer,
- a downstream gas injector situated at a distance L3 from an upstream end of the air inlet tube, and
- a diffuser;
- wherein the gas injection system constitutes a one-piece mechanical assembly that ensures a self-stable elementary flame;
- wherein the upstream gas injector comprises a single mechanical component configured to ensure both gas injection and mixing;
- and
- wherein the diffuser comprises a stabilizing element of diameter D5 and a concentrator of diameter D8 and length L7, the stabilizing element is pierced by holes distributed in two concentric circles of diameters D6 and D7, D7<D8<D6, and the length L7 is between 0 and D5.
