An apparatus having a substantially air-sealed, transparent, front through which a flame within the firebox may be viewed. The apparatus may include a burner configured to hold and burn a liquid fuel and positioned so as to cause a flame from the burning fuel to appear within the firebox. The liquid fuel may be ethanol. The apparatus may include an igniter that has a user-operated igniter control that may be operated by a user from outside of the firebox that, upon operation, causes the liquid fuel within the burner to be ignited. The apparatus may include an extinguisher that has a user-operated extinguisher control that may be operated by a user from outside of the firebox that, upon operation, causes the flame to be extinguished. The apparatus may include a fuel inlet located outside of the firebox, and a fuel channel between the fuel inlet and the burner. A fuel tank may also be provided.

A combustion apparatus is provided. The combustion apparatus includes a fuel reservoir storing fuel therein, and a main body connected to the fuel reservoir by a flexible tube. The main body receives fuel from the fuel reservoir and combusts the fuel therein. The main body is partitioned into an upper space and a lower space by a partition plate. The main body includes a combustor that is provided in the upper space and combusts fuel supplied from the fuel reservoir, a blower that is provided in the lower space to supply air to the combustor, and a heating unit that is removably coupled to the combustor and completely combusts air incompletely combusted in the combustor. The combustion apparatus completely combusts liquefied animal and vegetable oil, thus reducing a tar generation rate.

A fireplace device with a spiral flame includes a base, a glass stand, and a spiral air flow guide device fixed at an upper end of the base. The spiral air flow guide device includes an outer shell and an inner shell, and the inner shell and the outer shell are connected through the spiral air flow guide device. The inner shell and the upper end of the base are fixed together. A partition space is provided inside the inner shell. The partition space can accommodate a burner assembly. The outer shell is above an upper part of the base and is connected to the inner shell. A wall ring is arranged at a bottom of the outer shell. The glass stand is placed on the wall ring. A fire extinguishing cover is arranged at a top of the glass stand.
