Appl. No.:

13/444226

Inventors:

Adel B. Mansour - Mentor OH, US
Erlendur Steinthorsson - Pepper Pike OH, US
Brian P. Hollon - Moncks Corner SC, US
Jeffrey R. Lehtinen - Concord Township OH, US

International Classification:

F23L 7/00
F02M 63/00

US Classification:

431 2, 2395332

Abstract:

Provided is an injector having a plurality of micro-mixing nozzles having axes thereof pointing radially inwardly or outwardly with respect to a main axis of the injector and a plurality of micro-mixing nozzles having axes thereof extending axially with respect to the main axis of the injector. The arrangement of micro-mixing nozzles provides a means for fast and efficient mixing of fuels, such as highly reactive fuels including hydrogen. The arrangement of micro-mixing nozzles also achieves low NOx emissions.

Appl. No.:

12/503913

Inventors:

Brian Hollon - Moncks Corner SC, US
Adel B. Mansour - Mentor OH, US
Erlendur Steinthorsson - Pepper Pike OH, US

International Classification:

F02M 61/16

US Classification:

60740, 239404, 239 8

Abstract:

A nozzle assembly () comprises a first-fuel-inlet tube (), a second-fuel-inlet tube (), and a plate stack (). The nozzle-plate stack () defines a central circuit (), corner air circuits (), a first fuel circuit () and a second fuel circuit (). The fuel circuits () include a swirl chamber in which the fuel is swirled prior to being merged with the central circuit (). The corner air circuits () merge with the central circuit () downstream of the fuel circuits' merge and provide an additional swirling component to further shape the fuel-air stream prior to ignition.

International Classification:

F02M 53/04
F02M 61/16
F02M 53/08

Abstract:

Provided is an injector () having a plurality of injector modules () that include a spray cup having a chamber and a plurality of radial air passages for directing air radially into the chamber, and a pressure swirl atomizer attached to the spray cup and having a fluid passage for directing fluid axially into chamber and an air passage for directing air axially into the chamber. By providing radial and axial air flow and axial fuel flow into the chamber, the fuel may be mixed to prevent local hot spots that lead to high NOx emissions, and a stable flame may be maintained without autoignition and flashback. The axial air flow also prevents recirculation zones from forming at a base of the spray cup, provides improved atomization and enhanced combustion.
