The fuel conduit terminates short of the burner head and the wall of that conduit is provided with a plurality of holes. A further pipe surrounds at least the perforated part of the fuel conduit, and one end of the further pipe extends to the the burner head while the other end is sealed against the fuel conduit to form a mixing chamber between the outside of the fuel conduit and the inside of the further pipe. A second conduit is provided to conduct a given amount of air to the mixing chamber.
