Radiation burner for central heating boiler - has wire mesh burner face with curved section in downstream direction aligned with support aperture

摘要

The burner wind mesh face (4) has a curved section (5), dished in the outlet flow direction (AR). The curved section has a continuous axial cross section, in seamless and rotation symmetrical. It is fitted over an aperture (6) of a support (7). Its inlet aperture (8) corresponds to that in the support. Its height (H) corresponds at least to the radius of the curved section. ADVANTAGE - Larger burner face than the gas feed cross section and stable shape of the wire mesh face.
