The power of a gas burner with a crown and cap may traditionally be related to its diameter, i.e. its circumference. The invention provides a burner which not only has peripheral flames but also flames burning nearer the centre. This is obtained by means of a special crown and cap structure and by providing secondary air for the inwards directed flames by means of a scoop plate (S) which takes part of the primary air stream (A) supplied to the burner. The result is a burner which has an appreciably larger power as compared to traditional burners of the same diameter.
