Abstract
A compact cooking stove including a combustion area partially surrounded by a wind screen having a side opening which faces the wind to direct air to the burning fuel. An exhaust opening is formed adjacent a cooking pan placed at the top of the wind screen so that hot exhaust gases from the burning fuel pass upwardly toward the pan. In a first embodiment heat is supplied by a generally cylindrical burner plate including a recessed, central portion forming an alcohol fuel dish surrounded by a fairly broad rim. A plurality of pot-supporting tabs project upwardly from circumferentially spaced points about the rim to support a cooking pan above the fuel dish and rim. Heat from the burning fuel imparted to the bottom of the pan is radiated to the rim of the burner plate to heat the fuel in the fuel dish in order to promote vaporization of the fuel which increases the heat generated by the stove. A cooking pan is supported on several legs projecting upwardly from the top edge of the wind screen to form exhaust openings beneath the pan. When the stove of either embodiment is being transported, the rim of the cooking pan locks together with the rim of a cup to form a waterproof enclosure i…
