Burner comprising a reactor for catalytic burning

A burner, comprising a generally cylindrical reactor chamber (1) comprising a housing (1′) having a proximal end (1p) and a distal end (1d);

• a catalyst (4) provided in the distal end of the reactor chamber (1);
• a plurality of air inlets (22, 23;
• 24) arranged in the reactor wall at the proximal end, and configured to provide a rotating flow of the air injected into the reactor chamber by the provision of mixing means (6a) arranged around the air inlets;
• a fuel inlet (7) provided in the proximal end of the reactor chamber, arranged to inject the fuel into the rotating air flow;
• a flow homogenizer (8;
• 30) extending over the cross-section of the reactor chamber at a position between the fuel inlet (7) and the catalyst (4).
