Abstract
In various implementations, a burner assembly may include a body coupled to burner heads. The body may include one or more converging and/or diverging parts. For example, the body may include a diverging part proximate one or more of the burner heads of the burner assembly. The body may allow a predetermined fuel/air ratio to be provided to the burner head, in some implementations.
Claims20
A burner assembly comprising:
- a body comprising:
- a first end;
- a second end opposing the first end;
- a first section disposed proximate the second end, wherein the first section includes a first converging portion;
- a second section disposed proximate the second end and disposed proximate the first section, wherein the second section comprises a first diverging portion;
- and
- a third section disposed proximate the second end, wherein the third section comprises a second converging portion;
- wherein the second section is disposed between the first section and the third section of the body;
- one or more fuel inlets coupled proximate the first end of the body;
- and
- one or more burner heads coupled proximate the second end of the body.

A method of providing heat, wherein the method comprises:
- allowing at least a portion of a fuel stream to flow to at least one inlet of a burner assembly;
- allowing a primary air stream to flow at least partially into at least one of the inlets of the burner assembly;
- allowing at least a portion of the primary air stream and at least a portion of the fuel stream to at least partially mix in a body of the burner to form a mixed stream;
- allowing the mixed stream to flow to one or more burner heads of the burner assembly through at least one of:
- a first section of the body, wherein the first section comprises a first converging section;
- a second section of the body, wherein the second section comprises a first diverging section;
- or
- a third section of the body, wherein the third section comprises a second converging section;
- and
- allowing combustion of at least a portion of fuel in the mixed stream proximate one or more of the burner heads of the burner.
7 more elements
A burner assembly comprising:
- a first end of a body;
- at least two arms extending from the first end of the body, wherein each arm comprises a first end and a second opposing end;
- at least two fuel inlets, wherein each fuel inlet is coupled proximate the first end of an arm;
- a second end of the body opposing the first end, wherein the second end of an arm is coupled to the second end of the body;
- at least two first sections of the body, wherein each first section is disposed proximate the second end of an arm;
- at least two second sections of the body, wherein each second section is disposed proximate a first section, wherein at least one of the second sections comprises a first diverging part;
- at least one third section of the body, wherein each second section is disposed between at least one first section and at least one third section of the body;
- and
- one or more burner heads coupled proximate the second end of the body.
