Abstract
The burner possesses set of holes capable of directing high pressure combustion flame toward a upper center point concentrating heating power, extremely suitable for heating the bottom of a wok or any round bottom cooking vessel. With an adapter, another set of holes is capable of producing upward and outward spreading flame for flat bottom type cooking vessels. A protection guard can be put around the first wind guard preventing an operator accidentally touching the wind guard during cooking.
