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 fuel supply system for a gas burner assembly is provided. The gas burner assembly includes an inner burner stage positioned concentrically within an outer burner stage. The fuel supply system includes a fuel supply for providing a primary flow of fuel through a primary fuel conduit. A control valve and a modulating valve are operably coupled in series on the primary fuel conduit for regulating the primary flow of fuel. A first fuel supply conduit and a second fuel supply conduit tee off the primary fuel conduit to supply fuel to the outer burner stage and the inner burner stage, respectively. A shutoff valve is operably coupled to the first fuel supply conduit for stopping the flow of fuel through the first fuel supply conduit, e.g., during a simmer operation.

A lightweight liquid fuelled heater for use in tents or shelters. A removable liquid fuelled burner is supplied by a fuel cannister and a pump to create pressure in the cannister. A flame plate restrains the flame in a desired position during combustion. The burner is positioned within a support plate in the heater and the burner is removable from the support plate and heater. The flame plate is likewise removable from the burner. An adjustable damper is mounted in the stack and an adjustment wheel is located externally of the heater to allow variable draft between startup and steady state combustion. A removable tray may be used for wood burning.

The outdoor stove comprises a fuel (5) tank (6); a burner (12) fed by the fuel (6) in the fuel tank (5), which generates a flame; a combustion chamber (8) with at least one air inlet (2) and one air outlet (11), inside which the air is heated by the flame; wherein the stove comprises a base (1) on which the fuel tank (5) and the burner (12) are arranged, said base (1) comprising a fuel refueling pipe (7) in communication with the fuel tank (5), said refueling pipe (7) being separated from the flame generated by the burner (12).

It provides an outdoor stove that heats the environment by means of a ducted, controlled and adjustable air convection system.

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.
