PURPOSE:To enable to increase the changeable range for loading of heat, as well as to largely increase the radiant efficiency of a burner, by using instered ceramics having lots of winding pores as a burner plate, in a gas burner of infrared ray radiation type. CONSTITUTION:A burner plate 1 is made of sintered material such as alumina, cordierite, alumina-silica, silicon carbide, silicon nitride, zirconia or beta-spodumene. The burner plate 1 is fitted to a burner body 3 which is connected to a gas feed pipe 2. A burner port 4, consisting of lots of pores of which average diameter and mesh size on the surface 1a are less than 1.7mm. and more than 13 meshes, respectively, is provided in the burner plate 1. A nozzle 5 to inject fuel gas to the burner port is fitted to the feed pipe 2, and a porous plate 6 to disperse gas is provided in the burner body 3. The air is sucked into the gas feed pipe 2 by the injected fuel gas from the nozzle 5, and the mixed gas of fuel and air is uniformly fed to the whole surface of a burner plate 1, passing through the porous plate 6. The mixed gas is burned on the surface 1a of a burner plate 1, from which infrared rays are radiated. |
