Abstract
The invention relates to a radiant burner for boilers, consisting of a sheet metal support (1), with a gas feed line (3) leading to a gas inlet port (2) in the sheet metal support (1) and a curved burner surface (4) of wire cloth arranged at an opposite side of the sheet metal support. According to the invention, the burner surface (4) is of hemispherical shape and at least one similarly hemispherical gas distributor (5) of perforated sheet metal is arranged concentrically under the burner surface and is spaced therefrom at a distance (A) which is considerably smaller than the diameter (D) of the hemisphere of the burner surface (4) and is also affixed to the sheet metal support (1). The diameter (D.sub.1) of the gas inlet port (6) corresponds substantially to the diameter (D.sub.2) of the hemispherical gas distributor (5). Such a construction fulfills the requirements of a large gas inlet port, stability of the burner surface and good gas distribution over the burner surface.
