ABSTRACT A cooker for use in Chinese cooking includes a gas burner 1 comprising a burner body 3, an air supply pipe 9 and a gas supply pipe 5 arranged coaxially. The gas supply pipe 5 extends upwardly beyond the air supply pipe 9 and terminates in an outlet nozzle 7 where gas is burned. Air is guided towards and around the gas outlet nozzle 7 by an air supply fitting 11 comprising a number of vanes 15a-e arranged on a hub 16 which surrounds the periphery of the gas supply pipe 5. The vanes 15 radiate from the hub and extend along a line at an angle oblique to the radial direction. Particularly, the vanes 15a-e are twisted to for a part helical surface. Air blown into the burner through the air supply pipe 9 is guided by the vanes into a spiral path towards and around the gas outlet nozzle 7 to supply the gas with ample oxygen for combustion.
