Flammeholder for gasbrænder og brænder med en sådan flammeholder

The flame spreader (1) contains a set of rings (2) made from knitted metal wire with non-porous spacers (20) between them. These have internal diameters which are more or less equal to those of the rings, while there outer diameters are smaller. The spacers are thinner than the metal wire rings, and the difference between their outer diameters is equivalent to the spacers' thickness. The two end rings in the set have collars (132,232) which cover some four fifths of their outer surfaces, while the free end of the stack is closed by a blank cover (26) made from a heat resistant material. The burner also has a gas distribution chamber (81) fed with combustive air and fuel gas, connected to a combustion chamber (82) containing the flame spreader.
