ABSTRACT (Figure 1) A gas burner comprises a burner skirt 1 supporting a burner head 5 provided with combustion ports 6. A plate 9 notched at the edges allows part of the combustion mixture to escape round the bottom of the burner head and burn to form a retention flame below the main combustion ports 6. The flow of gas to the retention flame is metered by metering apertures formed by the bottom of the burner head and the notches in the plate 9. This construction allows the skirt to be made simply and inexpensively from materials such as mild steel, and to be vitreous enamelled, without sacrificing accuracy of metering of the supply to the retention flame.
