Abstract: A burner includes a diffuser wall delimiting an inner space in flow communication with an inlet passageway and forming a diffuser perforation for the gas mixture to pass from the inner space to an outer side of the diffuser wall where combustion occurs. A pilot chamber is formed in the inner space and delimited by a pilot portion of the diffuser wall, forming a pilot perforation, and by a pilot wall extended into the inner space. The pilot chamber forms pilot inlet openings supplying air/gas-air pre-mixture into the pilot chamber. A pilot gas opening supplies non-premixed fuel gas into the pilot chamber. A main chamber formed in the inner space is delimited by a diffuser wall main portion, forming a main perforation, and by the pilot wall. The main chamber delimits a main inner volume and is in flow communication with the inlet passageway to supply air/gas-air pre-mixture.
