Abstract: A fuel fired burner is provided for receiving a premixture of fuel and air. A ceramic flame support extends across the burner chamber and has a plurality of elongate slots through which the fuel and air flows. Each slot has a narrow constant dimension portion that opens into a wider constant dimension portion. The outlet end of the latter portion opens into a short diverging outlet. The arrangement is such that when the burner is operating within a given heat output range, the burner flame can move between the upstream and downstream ends of the diverging outlet to seek stabilization as the heat output changes within that range, without retracting into the slot upstream of the outlet.

Abstract: A flame support 20 has a plurality of discrete regions 22 through which fuel/air mixture can pass by means of burner ports 13 which extend through the support to a multiplicity of openings 25 at the flame supporting side 24. The support 20 comprises barriers 21/26 which extend between and separate the discrete regions 22. The barriers serve to prevent the passage of fuel/air mixture from upstream of the support to the downstream side 24 of the support in a region between the discrete regions. In burners provided with such a flame support, the likelihood of resonant combustion noise occurring has been found to be reduced.
