Abstract
A burner apparatus and a method of operating the burner apparatus can include a housing and an array maintained by the housing. The burner apparatus can function according to an air staged mode of operation. The array can include a group of low-capacity fuel swirlers and low-capacity air swirlers, wherein individual or groups of the low-capacity fuel swirlers and/or low-capacity air swirlers among the array can be turned on or off based on a required burner capacity.
Claims14
A burner apparatus, comprising:
- a housing;
- an array maintained by the housing and which functions according to an air staged mode of operation, the array comprising a plurality of low-capacity fuel swirlers and low-capacity air swirlers, wherein individual or groups of low-capacity fuel swirlers and/or low-capacity air swirlers among the array are turned on or off based on a required burner capacity;
- and
- a common fuel source and a common air source are operable to supply fuel and air to at least one of the low-capacity fuel swirlers and the low-capacity air swirlers among the plurality of low-capacity fuel swirlers and low-capacity air swirlers, and wherein the fuel and air are mixed within each swirler to form a combustible mixture.
