A portable warming assembly includes a canister and a lid that is removably attachable to the canister for closing the canister. A roll of solid fuel is positionable inside of the canister and the roll of solid fuel is comprised of a combustible material. A container containing a liquid fuel is provided and a pre-determined amount of the liquid fuel is pourable onto the roll of solid fuel when the roll of solid fuel is positioned in the canister. In this way the liquid fuel enhances combustion of the roll of solid fuel. A plurality of rocks is provided and each of the rocks is positionable on top of the roll of solid fuel when the roll of solid fuel is positioned in the canister. Each of the rocks heats the ambient air when the roll of solid fuel and the liquid fuel are burned for heating an interior space.

A fuel-burning device includes a container defining a receptacle and having an opening which is at an end of the receptacle. The opening has a first width. The fuel-burning device also includes a fixing mechanism mounted in the container through a fixing member. The fixing member has an end resiliently fixed on a periphery of the receptacle. The fixing member is radially compressible. When the fixing member is not compressed, the end thereof has a second width which is greater than the first width. The end of the fixing member is compressible to a third width which is smaller than the first width.

A transformable wick device includes a plurality of bodies connected together. The plurality of bodies has flexible connections, and therefore positionable along a line of various types.

A fire display device includes a fuel reservoir, a cap, a wick, and a fixture assembly for holding the wick. The cap is positioned within the fuel reservoir and forms a recess. The cap has at least one fuel injection hole and a first positioning hole both extending therethrough and in communication with the chamber and the recess. The wick is inserted through the first positioning hole and has a top end positioned above the cap and a bottom end positioned below the cap. The fixture assembly includes a clamping member with first and second clamping surfaces. The wick is clamped between the first and second clamping surfaces. The first and second clamping surfaces are inserted through the first positioning hole.

A wick management apparatus includes a base and a housing. The base defines a receptacle to hold wicking media. The housing engages at a first end with the base. The housing includes a tube extending away from the first end. The tube defines a first interior channel between the first end and an exit hole on a sidewall of the tube. The tube also defines a second interior channel between an entry hole on the sidewall of the tube and a hole at a second end of the housing. A length of the sidewall between the exit hole and the entry hole is configured to support pressure of a user's thumb against the wicking media and translational movement of the wicking media between the exit hole to the entry hole.

A combustion device having a double-layer structure includes a main body, which is double layered, including an inner-layer wall and an outer-layer wall disposed outside of and spaced from the inner-layer wall such that the inner-layer wall and the outer-layer wall include a hollow disposed therebetween. The inner-layer wall forms a fuel receptacle with an opening. A wick has an end defining fuel-drawing end inserted into the fuel receptacle through the opening.
