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.
