Abstract
A burner apparatus and method of operating the burner apparatus include a burner housing, and a group of fuel and air swirlers maintained by the burner housing, with the group of fuel and air swirlers supplied by a common fuel and air source. The fuel and air can be directed to one or more of the fuel and air swirlers at a time. Each fuel and air swirler among the group of fuel and air swirlers can mix the fuel and the air, resulting in a combustible mixture of the fuel and the air downstream of the group of fuel and air swirlers. The burner apparatus be implemented as a low NOx multi-port burner apparatus.
Claims17
A burner apparatus, comprising:
- a burner housing;
- and
- a plurality of fuel and air swirlers maintained by the burner housing, wherein the plurality of fuel and air swirlers is supplied by a common fuel and air source, wherein fuel and air are directed to at least one of the plurality of fuel and air swirlers at a time, and wherein each fuel and air swirler among the plurality of fuel and air swirlers mixes the fuel and the air, resulting in a combustible mixture of the fuel and the air downstream of the plurality of fuel and air swirlers, wherein the burner housing comprises a plurality of fuel inlets wherein a first fuel inlet among the plurality of fuel inlets leads to a first fuel vessel and contains a first path to enter a center core of the plurality of fuel and air swirlers, and wherein a second fuel inlet among the plurality of fuel inlets leads to a second vessel and contains a second path to enter an outer ring of the plurality of fuel and air swirlers.
A burner apparatus, comprising:
- a plurality of fuel and air swirlers, wherein the plurality of fuel and air swirlers is supplied by a common fuel and air source, wherein fuel and air are directed to at least one of the plurality of fuel and air swirlers at a time, and wherein each fuel and air swirler among the plurality of fuel and air swirlers mixes the fuel and the air, thereby resulting in a combustible mixture of the fuel and the air downstream of the plurality of fuel and air swirlers;
- a plurality of fuel inlets wherein:
- a first fuel inlet among the plurality of fuel inlets leads to a first fuel vessel and contains a first path to enter a center core of the plurality of fuel and air swirlers;
- and
- a second fuel inlet among the plurality of fuel inlets leads to a second vessel and contains a second path to enter an outer ring of the plurality of fuel and air swirlers.
A method of operating a burner apparatus, comprising:
- supplying air to a plurality of fuel and air swirlers by a common air source through an air inlet, wherein the air inlet is split a plurality of flow paths,
- supplying a plurality of fuel and air swirlers by a common fuel source via a plurality of fuel inlets, wherein the plurality of fuel and air swirlers comprises a center core of the plurality of fuel and air swirlers and an outer ring of the plurality of fuel and air swirlers;
- wherein a first fuel inlet of the plurality of fuel inlets leads to a first fuel vessel and contains a first path to the center core of the plurality of fuel and air swirlers;
- and
- wherein a second fuel inlet of the plurality of fuel inlets leads to a second fuel vessel and contains a second path to the outer ring of the plurality of fuel and air swirlers,
- directing fuel and air to at least one of the plurality of fuel and air swirlers at a time, wherein each fuel and air swirler among the plurality of fuel and air swirlers mixes the fuel and the air to result in a combustible mixture of the fuel and the air downstream of the plurality of fuel and air swirlers.
