Problems solved by technology
However the fire grid is not powerful enough and the entire structure is not efficient enough for wok cooking.
Such power is beyond reach of single ring low pressure gas stoves.
Another drawback of using low pressure gaseous fuel is its stove being more susceptible to wind during outdoor cooking.
However they share several disadvantages that prevent them from reaching high quality oriental cooking.
The second disadvantage is the low pressure burner which they utilize does not have center flame heating to the bottom of a wok.
The disadvantage of not using a center flame is in many burner designs, for example U.S. Pat. Nos. 6,234,064, 6,098,611, D386,936, 4,553,524, 4,353,347.
For a wok, this heat conducting downward to its bottom is extremely inefficient.
Yet another disadvantage of the aforementioned stove constructions is to allow the flame to ext

Abstract
A portable outdoor stove is provided which includes a burner primarily comprising an outer and inner pieces bolted tightly to form a small gas/air mixture chamber for accepting and maintaining high pressure gaseous fuel, a wind guard of cylinder shape capable of tightly coupled with a cooking vessel and possessing slot opening of less than 180° toward its top for exhaust outlet, adjustable means for supporting the burner and positioning flame from burner onto bottom of cooking vessel, short or long legs to support the wind guard and the cooking vessel. A protection guard can be put around the first wind guard preventing an operator accidentally touching the wind guard during cooking.
