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.
