A gas fireplace combustion device structure includes a simulated solid fuel and a combustor under the simulated solid fuel. The combustor has a fire exit hole facing the simulated solid fuel, a combustion air inlet passage under the combustor, and a specific slot at the combustor to define a third combustion air inlet. A partition is installed under the combustor; a second combustion air inlet leading to fire exit hole is formed between the partition and the combustor; the combustion air inlet passage is provided for supplying air to the second and third combustion air inlets; a combustion air slot is formed at the middle of the simulated solid fuel to resupply combustion air to the flame above the simulated solid fuel in order to achieve a two-time sectional combustion. This invention can control and resupply combustion air to the flames in different areas to improve the combustion effect.

An improved outdoor patio table with centrally secured outdoor patio heater, and methods of using the same are disclosed. The outdoor patio heater may be secured to the within the patio table without increasing the exterior perimeter of the patio table when securing or removing the patio heater. The patio table may be suitable for applications where there are a plurality of tables in a line and when a patio heater is removed frequently.

The application discloses an infrared stove and an infrared split stove set. The infrared stove includes an outer casing, an inner cover, an ejector tube, a gas nozzle and an infrared reaction layer. The inner cover is nested with the outer casing to form a stove body. The infrared reaction layer is provided on the stove body. A first accommodating cavity is provided between the infrared reaction layer and the inner cover. A second accommodating cavity is provided between the inner cover and the outer casing. The ejector tube is arranged on the inner cover, communicates with the first accommodating cavity and the second accommodating cavity, and has a gas inlet. The gas nozzle is arranged on the outer casing, and is arranged opposite to the gas inlet and at a spacing. The infrared stove adopts flameless combustion, with more stability, more resistance to severe environments, and better windproof property.

A fireplace and method of manufacturing a fireplace. Embodiments of the fireplace comprise a combustion chamber, a front opening allowing viewing within the combustion chamber, and a back wall opposite the front opening. The back wall can be controllably switched between an opaque state and a transparent state. A combustion region between the front opening and the back wall is adapted to provide a flame. A controller coupled to the back wall enables a user to switch the back wall between the opaque and transparent states. In embodiments the back wall comprises a glass panel and switchable film on the glass panel. The controller is coupled to the switchable film.

A firebox is provided for use in a gas fireplace, the firebox comprising: a back which includes at least one combustion fan aperture, an upper end and a lower end and a length therebetween, a pair of sides, each side including an upper end, a lower end, a first riser which has an inner section and an outer section, the inner section attached to the back, a first flange, which is parallel to the back and extends outward from the back, and a second riser, wherein the outer section of the first riser, the first flange and the second riser extend above the upper end of the back and below the lower end of the back; a top which is attached to the inner section of the first risers and to the back at the upper end; and a base which is attached to the inner section of the first risers and to the back above the combustion fan aperture, to define an opening. The fireplace is also provided.

A process of producing potable water, by combining a hydrocarbon containing fossil fuel with oxygen, in a combustion device, such as a home heating or utility unit to produce a flue gas of water vapor and carbon dioxide, and condensing the water vapor in the flue gas to yield potable water. The combustion device can produce heat or electricity. The water vapor can be condensed with one or more heat exchange devices. The source of oxygen can be air, pure oxygen, or nitrogen reduced air. The source of oxygen can be humidified, such as with a non-potable water source or non-potable water can be added to the flue gas. The carbon dioxide and/or nitrogen in the flue gas can be reduced or removed before the condensation step(s). The pressure of the flue gas can be increased prior to condensation of the water vapor. Natural gas is a preferred fuel.

A firebox is provided for use in a gas fireplace, the firebox comprising: a back which includes at least one combustion fan aperture, an upper end and a lower end and a length therebetween, a pair of sides, each side including an upper end, a lower end, a first riser which has an inner section and an outer section, the inner section attached to the back, a first flange, which is parallel to the back and extends outward from the back, and a second riser, wherein the outer section of the first riser, the first flange and the second riser extend above the upper end of the back and below the lower end of the back; a top which is attached to the inner section of the first risers and to the back at the upper end; and a base which is attached to the inner section of the first risers and to the back above the combustion fan aperture, to define an opening. The fireplace is also provided.

The present invention provides an improved outdoor patio table with centrally secured outdoor patio heater, and methods of using the same. The outdoor patio heater may be secured to the within the patio table without increasing the exterior perimeter of the patio table when securing or removing the patio heater. The patio table may be suitable for applications where there are a plurality of tables in a line and when a patio heater is removed frequently.

A home cooking appliance includes a cooking compartment, a gas burner tube in the cooking compartment, a gas supply orifice holder coupled to a gas supply line at a first end and having a gas supply orifice at a second end. The gas supply orifice is configured to inject gas from the gas supply line into the gas burner tube. The home cooking appliance further includes an anti-rotational housing fixing a position of the gas supply orifice holder with respect to the gas burner tube.

The disclosed technology includes a portable fire pit. In one example, the portable fire pit includes a housing defining a housing cavity and an opening to the housing cavity, and a burner positioned within the housing cavity. The housing includes a front wall that defines a length of the housing, a sidewall that defines a width of the housing, and a base. A distance between the base and the opening defines a height of the housing, and the height is greater than the width. The burner includes a first arm coupled to a second arm in a spaced apart configuration, and a plurality of holes on a top surface of the first and second arms. The first and second arms extend parallel to one another and to the front wall.
