Abstract: A wick-type combustion apparatus for liquid fuels comprises: a pair of cylindrical walls extending vertically and opposed to each other with a gap; a cylindrical wick vertically movable as guided between and along the walls; a slit-form cylindrical fuel passage opening provided in the outer wall and adapted to be opened and closed by the descent and ascent, respectively, of the wick; a fuel trap chamber provided around the opening in communication therewith; and a cylindrical porous member vertically extending in the chamber.A flame or flames remaining after the descent of the wick can be instantaneously blown out by a blast of an explosive combustion which occurs in the fuel trap chamber. The porous member serves to reduce the amount of unburnt fuel used for the explosive combustion, so that an abnormal rise of flame or flames attendant with the explosion can be prevented.
