  • Direct injection multipoint nozzle
    Patent number: 9810186
    Abstract: Provided is an injector (30) having a plurality of injector modules (44) 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.

  • DISTRIBUTED INJECTION WITH FUEL FLEXIBLE MICRO-MIXING INJECTORS
    Publication number: 20120258409
    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.
