A safe combustion device includes a stove body including a fuel reservoir, a fuel tray disposed vertically above and separately from the fuel reservoir and defining an air flow passage, and a wick with an upper end connected to the fuel tray and disposed in the air flow passage and a lower end disposed in a reservoir space defined by the fuel reservoir respectively.

A combustion device includes a fuel reservoir which includes a container and a tray disposed on the container and a wick inserted through a first hole of the tray and into a space of the container. Further, the combustion device includes a heat insulating and dissipating device which includes a heat insulating member and a heat dissipating member encircling the wick. The heat insulating member is made of a non-metallic material. The heat dissipating member is made of a metallic material.

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 smokeless safe combustion device includes a stove body and a flow guiding device. The stove body has opposite first and second sides and includes a wick disposed between the first and second sides. The wick is spaced from the first and second sides at first and second distances respectively. The flow guiding device includes a first and second shielding member respectively connected to the first and second sides of the stove body. The wick is spaced from the first and second shielding members at third and fourth distances respectively. The third distance is greater than the first distance and the first shielding member is spaced from the first side. The fourth distance is greater than the second distance and the second shielding member is spaced from the second outer side.

A portable, collapsible holder for a cooking container has a threaded collar that screws onto the neck of a chafing dish fuel container. Three panels are each rotatably connected to the collar with an offset hinge. The panels rotate between a first collapsed position in which the panels contact a top surface of the collar and a second position in which the panels are in a deployed position at an angle of about 105 to 155 degrees outward from the top surface. Rotation stops on the panel and collar limit the rotation.

The present disclosure includes: a casing with an open top; a combustion compartment including: a combustion chamber disposed inside the casing to generate a blue flame-shaped flame by burning vegetable oil; a combustion cover enclosing the combustion chamber therein, and having an inner wall spaced apart from an outer wall of the combustion chamber by a predetermined distance to form a predetermined cavity; and an air chamber disposed below the combustion cover with a lower end of the combustion chamber being positioned above, wherein the air chamber supplies outside air toward the combustion chamber during combustion of the vegetable oil; an oil tank that supplies the vegetable oil to the combustion chamber; and a control unit that controls whether or not to drive the air chamber, the flow and supply pressure of the outside air, and whether or not to supply the vegetable oil and a supply amount of the vegetable oil.
