Abstract: Apparatus for burning spirit or similar fuel with a fuel container (10) filled with a fuel absorbing mass with partly exposed surface, from which fuel to be burned evaporates. A burner tube (16) is so arranged with respect to the exposed surface that suction of combustion air into the tube is secured. The fuel container is separate and removable from the apparatus and has top, bottom and side walls enclosing the absorbing mass. The top wall for forming the exposed surface includes a central opening, the area of which comprises a fraction of the total area of the upper top wall. The opening is surrounded by a rim portion (26) of the top wall substantially raised with respect to the rest of the top side of the container. The tube (16) is surrounded by an outer fixed tube (20) with an upper end extending above the level to which the burner tube is normally intended to extend.
