Abstract: A wick-burning and ventilation and flow-guide structure includes a wick tray, a heat isolation cover, and a wick. The heat isolation cover has support sections that are extended to form protrusion sections insertable into and mounted in mounting holes of the wick tray for secured combination and easy separation. The wick tray and the heat isolation cover provide a dual-layered heat isolation effect and also achieve an effect of heat dissipation. The wick is made of a metallic or ceramic material and has a surface over which a flame-blocking heat-isolating sleeve is fit to prevent downward spreading of flaming. A wind-shielding hood is provided on the fuel container to define therebetween a flow-guide opening for smooth ingress of air, preventing flaming from jumping.

A user input device is electrically connected to the control circuit.

Abstract: A device for producing a stable and augmented flame includes a fluid-inducing assembly and a shield. The fluid-inducing assembly includes a flow-diverting mechanism defining a flow-intake end and a flow-accelerating end and includes a plurality of vanes extending from the flow-intake end to the flow-accelerating end. The plurality of vanes is circumferentially disposed and spaced from one another. Furthermore, two vanes include a space defined therebetween, and the space defines a passage which is spiral-shaped. The flow-diverting mechanism further includes a covering member with an enclosed circumferential edge circumferentially surrounded. Thus, each vane in the flow-accelerating end is encircled by the covering member, and each vane in the flow-intake end is exposed to outside and not covered by the covering member. In addition, the shield is hollow and is disposed above the fluid-inducing assembly.

The second tube is not connected to the first tube, and an inlet line through which an air is supplied is connected to the first tube.

Abstract: An apparatus for producing a sustained flame, comprising: a first reservoir for containing a first flame-fueling liquid; a second reservoir for containing a second flame-fueling liquid; a first wick having a first end disposed within the first reservoir and a second, flame-bearing end generally located above the first end; a second wick disposed substantially adjacent to the first wick, having a first end disposed within the second reservoir and a second, flame-bearing end above the first end; and at least one air channel disposed to supply oxygen to each wick, where a first end of the at least one air channel is generally located near the flame-bearing end of each wick; whereby, when the first and second flame-fueling liquids are supplied to the first and second reservoirs, the first and second flame-fueling liquids are communicated up the first and second wicks to fuel flames emanating from the flame-bearing ends of the first and second wicks.

Abstract: A combustion cylinder structure for an oil burner capable of stably carrying out minimum combustion as well as controlling the combustion operation over a wide range. The structure is so constructed that a lower heat-impermeable cylinder of an outermost cylinder construction of a multi-cylinder combustion assembly is provided at the upper end thereof with an inward collar, which is provided at the inner end thereof a cylindrical section for rectifying air introduced through a gap between the cylindrical section and an outer cylindrical member to guide it along the cylindrical member. Also, the collar is provided with through-holes, which are arranged in the circumferential direction to guide air along a heat-impermeable cylinder arranged on the heat-impermeable cylinder, resulting in preventing the generation of a turbulent flow between the outer cylindrical member and the heat-permeable cylinder.

Abstract: The present invention relates to a combustion equipment to be employed for heating in domestic use or the like. The combustion equipment is provided with an air control cylinder having a closed bottom surface inwards of an inner flame cylinder, and an outer control cylinder inwards of a vaporizing portion, and accordingly, radical deterioration of the CO/CO.sub.2 characteristic can be prevented.

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.
