A refillable torch canister includes a container having top which includes a fill opening and a cover including a fill opening which can be axially aligned with the fill opening of the top to permit insertion of fuel therethrough, and which can be moved so the fill openings are out of alignment precluding fluid to pass therethrough. Also, included is a pre-filled fuel container having spout with a complementary configuration to be received within the fill openings.

An invention is provided for a spiral flame torch apparatus. The spiral flame torch apparatus generally includes a base having a bottom plate, lower stabilization plate, and an upper stabilization plate. Situated on the base is a glass halo comprised of a plurality of rounded glass sheets. The glass sheets each include vertical sides that overlap one the vertical side of another rounded glass sheet, leaving gaps between the sheets. Disposed within the glass halo is a paraffin based flame source having a large wick disposed centrally within the flame source.

A fuel container has a fuel reservoir, a flame guard affixed atop the fuel reservoir and providing a wick holder, and a fuel container flange at the connection of the flame guard to the fuel container extending radially outward from the fuel container.

A combustion device includes a burner and a shield. The burner includes a fuel container having a top defining an opening. A wick has a bottom end and a top end. The bottom end is inserted into the fuel container via the opening, and the top end protrudes outside the fuel container and is at a first height in a vertical direction. The shield defines a space, and the burner is disposed within the space. The shield has a first through-hole extending therethrough and communicating the space and the outside of the shield. The first through-hole is at a second height in the vertical direction, and the second height is less than the first height.

A fuel-operated vehicle heater, combustion chamber assembly unit includes a combustion chamber housing (14) having a combustion chamber bottom (18) and a combustion chamber circumferential wall (16) extending in a housing longitudinal axis (L) direction to define a combustion chamber (20). A porous evaporator medium (60) is on the combustion chamber circumferential wall or/and the combustion chamber bottom, at an inner side facing the combustion chamber. A fuel feed line (62) feeds liquid fuel into the porous evaporator medium. A first combustion air feed device (68), associated with the combustion chamber bottom, feeds primary combustion air (VP) into a first combustion zone (50) at which the porous evaporator medium is arranged. A second combustion air feed device (70), following the first combustion zone in the housing longitudinal axis direction feeds secondary combustion air (VS) into the combustion chamber at an axially spaced location from the first combustion zone.
