A burner includes a generally cylindrical reactor chamber (1) including a housing (1′) having a proximal end (1p) and a distal end (1d). In the distal end of the reactor chamber (1) there is provided a catalyst (4). A fuel inlet (7) is provided in the proximal end of the reactor chamber. There are also a plurality of air inlets (22, 23; 24) arranged in the reactor wall at the proximal end. The inlets are configured to provide a rotating flow of the air injected into the reactor chamber. There is also provided 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).

1. A catalytic 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 (24a, 24b) 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), and comprising a partition member in the form of a wall dividing the reactor chamber in two compartments, a first compartment wherein the mixing takes place, and a second compartment downstream of the first compartment wherein the flow is homogenized to exhibit essentially linear flow of the gases. 2. The burner as claimed in claim 1, wherein the fuel inlet comprises a fuel atomizing nozzle (7′). 3. The burner as claimed in claim 1, wherein the air inlets comprise apertures (24a) partly covered by flaps (24b) arranged to redirect the air flow in an essentially tangential direction so as to cause said rotation. 4. The burner as claimed in claim 1, wherein the flow homogenizer comprises a perforated partition member (30, 32; 36, 38). 5. The burner as claimed in claim 4, wherein the flow homogenizer is a mesh (36, 38). 6. The burner as claimed in claim 4, wherein the flow homogenizer (8; 30) comprises a central part (31) that is not perforated. 7. The burner as claimed in claim 1, wherein the housing is doubled-walled (5′, 5″) to provide a cooling jacket (12). 8. The burner as claimed in claim 7, having a distal water inlet (12in) and a proximal water outlet (12out) to and from the cooling jacket (12), respectively. 9. The burner as claimed in claim 3, wherein the flaps form an angle with respect to the reactor wall of 15-60°. 10. The burner as claimed in claim 2, wherein the flow homogenizer comprises a perforated partition member (30, 32; 36, 38). 11. The burner as claimed in claim 3, wherein the flow homogenizer comprises a perforated partition member (30, 32; 36, 38). 12. The burner as claimed in claim 5, wherein the flow homogenizer (8; 30) comprises a central part (31) that is not perforated. 13. The burner of claim 1, wherein, the fuel inlet and air inlets are separate so that the fuel and the air are introduced separately in the reactor and then mix to form a homogeneous mixture before contact is made with the catalyst and before combustion occurs,wherein the fuel inlet comprises a fuel atomizing nozzle (7′),the flow homogenizer (8; 30) extends over an entirety of the reactor chamber at the cross-section of the reactor chamber at a position between the nozzle (7′) and the catalyst (4), andin the second compartment downstream of the first compartment, the flow is homogenized to exhibit linear flow of the gases. 14. The burner of claim 1, wherein, the fuel inlet and air inlets are separate so that the fuel and the air are introduced separately in the reactor and then mix to form a homogeneous mixture before contact is made with the catalyst and before combustion occurs,wherein the fuel inlet comprises a fuel atomizing nozzle (7′),the flow homogenizer (8; 30) extends over the cross-section of the reactor chamber at a position between the nozzle (7′) and the catalyst (4), andin the second compartment downstream of the first compartment, the flow is homogenized to exhibit linear flow of the gases. 15. The burner of claim 13, wherein, the partition member is comprised of a plurality of openings (32) of at least three different sizes, the openings breaking up turbulent rotational flow, with a center of the partition member including a flame shield (8′, 31) free of any openings. 16. The burner of claim 14, wherein, the partition member is comprised of a plurality of openings (32) of at least three different sizes, the openings breaking up turbulent rotational flow, with a center of the partition member including a flame shield (8′, 31) free of any openings. 17. The burner of claim 13, wherein, the partition member is comprised of a mesh (34) covering the cross-section of the reactor chamber, the mesh providing square openings (38), the square openings breaking up turbulent rotational flow, with a center of the partition member including a flame shield (8′, 31) free of any openings. 18. The burner of claim 14, wherein, the partition member is comprised of a mesh (34) covering the cross-section of the reactor chamber, the mesh providing square openings (38), the square openings breaking up turbulent rotational flow, with a center of the partition member including a flame shield (8′, 31) free of any openings. 19. The burner of claim 14, wherein, the proximal end (1p) of the reactor chamber (1) is comprised of a distributor plate (20) with the fuel inlet being a fuel atomizing nozzle (7) centrally located within the distributor plate, and the air inlets being arranged concentrically around the nozzle at a periphery of the distributor plate, the air inlets including circular baffles (24) within the distributor plate that provide rotating flow of the air into the first compartment. 20.
