In order to create a safe and simply designed fire column, the flame of which is fed from a fuel tank, in particular for bioethanol, and is surrounded by an outer casing (4), wherein supply air flows in largely axially in the lower region of the outer casing via a plurality of guide elements (3) and is preferably set in helical rotation to form a swirling flame, according to the invention the outer casing (4) is placed over the guide elements (3). The outer casing (4) is preferably centered in an upright position by outer edges (3a) of the guide elements (3).

A pressure-type alcohol stove includes a stove body, an upper cover, a pre-heating pipe, and an automatic liquid-feeding device, wherein the upper cover is arranged on the stove body and is matched with the stove body to form a vaporization cavity, the pre-heating pipe penetrates through the upper cover and has a bottom end located in the stove body and a top end partially stretching out of the upper cover, a pre-heating cavity is formed around the pre-heating pipe, spirally-distributed spray holes are formed through the upper cover, air jet holes used for air jetting and pre-mixing are formed through an upper part of in the pre-heating pipe.

Compared with traditional alcohol stoves, the alcohol stove of this invention has higher power and efficiency.

A hot tub including a hot tub basin with a plurality of seats formed therein, the hot tub basin configured to hold and recirculate water, a housing surrounding the hot tub basin, and one or more fire fixtures provided proximate an upper portion of the hot tub basin to selectively produce open flame.

A method of fueling a flame, a fuel, and a fuel burning system is provided. The system has a melted wax reservoir, a fuel, a melting grate, and a wick. The fuel has a body, a priming section, a front wall, and a bottom surface. The priming section is vertically spaced from the bottom surface and extending from the front wall to create an overhang. The priming section extends along less than the entire length of the front wall. The melting grate is configured to support the fuel. The melting grate extends above the melted wax reservoir so that fuel melted on the melting grate can be received into the melted wax reservoir. The wick has an at least partially hollow core forming a burn chamber extending above the melting grate. The fuel is configured to be positioned so the overhang is located over or adjacent to the wick.
