Abstract
A burner adapted for use with alternative fluid fuels is provided. The burner includes a cartridge that comprises a nozzle with passage means therein. The nozzle passage means include an entrance adapted to receive a liquid fuel and a plurality of exit ports to discharge the liquid fuel in the direction of the combustion zone. An annular channel is formed around the nozzle and is adapted to supply a gaseous fuel or an atomizing agent for the liquid fuel to slot means, which tangentially communicate with each exit port so that the respective fluids passing through the exit ports and slot means intimately mix and are directed to the combustion zone. Fin means associated with the cartridge impart a swirling pattern to combustion air admitted into the furnace cavity.
Claims18
A burner assembly mounted within a generally cylindrical furnace cavity, comprising in combination,
- (A) a burner having a generally cup shaped combustion zone;
- (B) a dual fuel feed cartridge adapted to discharge alternative fluid fuels in the direction of said combustion zone, said cartridge having;
- (a) a nozzle mounted in said cavity;
- (b) passage means in said nozzle having an entrance adapted to receive a liquid fuel and a plurality of exit ports to discharge said fuel toward said cup;
- (c) slot means tangentially communicating with each said exit port and defining a plurality of slots to direct fluids into said cup, said slot means located in said nozzle;
- (d) fin means surrounding said slot means (c) to swirl combustion air admitted into said cavity, as it is supplied to said cup;
- (e) means for conducting a liquid fuel to said passage means (b);
- (f) means for conducting a gaseous fuel or atomizing agent to said slot means (c);
- (g) means for selectively activating and deactivating said means (e) and (f) to conduct alternative fuels to said cup if desired.
A dual fuel feed cartridge adapted to supply alternative fuels to a radiant cup burner assembly of the type mounted within a generally cylindrical furnace cavity, said cartridge comprising:
- (a) a collar mounted within said cavity;
- (b) fin means extending from and surrounding said collar to impart a swirling pattern to combustion air admitted into said cavity as it is supplied to said cup;
- (c) a nozzle mounted within said collar;
- (d) nozzle passage means including an entrance adapted to receive a liquid fuel and a plurality of exit ports to direct said liquid fuel toward said cup;
- (e) slot means tangentially communicating with each said exit port and defining a plurality of slots to direct fluids into said cup;
- (f) means forming a generally annular passage between said collar and said nozzle, said annular passage to supply a gaseous fuel or atomizing agent to said slot means (e);
- (g) means for conducting a liquid fuel to said nozzle passage means (d);
- and
- (h) means for conducting a gaseous fuel or atomizing agent to said annular passage;
- and
- (i) means for selectively activating and deactivating said means (g) and (h) in a manner to provide said alternative sources of fuel to said cartridge.
