Abstract
A mixture fitting for use in a combustible gas system, for example, a fireplace. The mixture fitting may include a first portion configured to be coupled to a combustible gas source and a second portion configured to be coupled to a burner assembly. The first and second portion together from a gas passage. The mixing fitting also includes an air orifice extending from an exposed surface of the mixture fitting to the gas passage. The air orifice is configured to allow primary air to travel through the air orifice and into the gas passage to facilitate mixing of air with the combustible gas. Alternatively, the air orifice may be angled, and multiple air orifice may also be provided.
Claims20
A mixture fitting for use in a combustible gas system, the mixture fitting comprising:
- a first portion configured to be coupled to a combustible gas source;
- a second portion configured to be coupled to a burner assembly, wherein the first and second portions define a gas passage;
- and
- an air orifice defined by the mixture fitting extending from an exposed surface of the mixture fitting to the gas passage and configured to allow primary air to travel through the air orifice and into the gas passage.
An apparatus for mixing air with combustible gas, the apparatus comprising:
- a combustible gas source;
- and
- a mixture fitting defining a gas passage and an air orifice extending from an exposed surface of the mixture fitting to the gas passage, wherein the combustible gas source is coupled to the mixture fitting to deliver combustible gas to the gas passage, and wherein the air orifice is configured to provide primary air to the gas passage for mixture with the combustible gas.
A gas fireplace comprising:
- a combustion chamber enclosure defining a combustion chamber;
- a burner assembly disposed within the fireplace, wherein the burner assembly includes:
- a burner disposed to combust a combustible gas and air mixture within the combustion chamber, wherein the burner defines a burner tube aperture,
- a burner tube coupled to the burner tube aperture, and
- an air shutter coupled to the burner tube;
- and
- a mixture fitting defining a gas passage and an air orifice, wherein combustible gas is delivered through the gas passage and mixed with primary air entering the gas passage through the air orifice to form the combustible gas and air mixture and wherein the mixture fitting is configured to deliver the combustible gas and air mixture to the burner through the burner tube.
A method for the mixing of combustible gas and air, the method comprising the steps of:
- providing a combustible gas source;
- and
- providing a mixture fitting that defines a gas passage and an air orifice oriented at an angle in a direction of a normal flow of the combustible gas, wherein the combustible gas source delivers combustible gas to the gas passage and wherein the air orifice provides primary air to the gas passage for mixture with the combustible gas.
A method for generating a combustible gas and air mixture in a gas fireplace, the method comprising the steps of:
- supplying combustible gas from a combustible gas source;
- conducting the combustible gas from the combustible gas source to a mixture fitting, wherein the mixture fitting defines a gas passage and an air orifice;
- passing the combustible gas through the gas passage;
- providing primary air into the gas passage through the air orifice;
- mixing the air with the combustible gas within the gas passage to form the combustible gas and air mixture;
- and
- directing the combustible gas and air mixture from the mixture fitting.
