Abstract:
In a liquid fuel burner including a nonconsumable wick for drawing up by capillarity of a draw-up section liquid fuel composed mainly of alcohol contained in a fuel tank and for burning it up at a tip flame-producing section, a wick holder for holding the wick with a flame-producing section of predetermined length maintained above the wick holder, an igniter for lighting the wick and a closure cap for preventing evaporation capable of sealing the wick operably and closably,a nonconsumable wick for a liquid fuel burner comprising an integral flame-producing section which is noncircular in cross-sectional shape and has a total exposed surface area above the wick holder equal to the cross-sectional area of the flame producing section added to the peripheral dimension of the flame-producing section multiplied by the predetermined length of the flame-producing section above the wick holder,whereby the stabilized flame length is achieved more quickly than with a wick having a circular cross sectional shape.
