A system for supporting a plurality of fuel nozzles in a combustor includes a plurality of fuel nozzles coupled to a fuel nozzle support housing proximate an upstream end of each fuel nozzle, a plurality of swirler vanes rigidly coupled to respective fuel nozzles proximate an intermediate portion of the fuel nozzle, a plurality of shrouds rigidly coupled to respective swirler vanes, each shroud having an upstream end adjacent the intermediate portion of the fuel nozzle and a downstream end and a support plate rigidly coupled to the plurality of shrouds proximate an intermediate portion of each of the shrouds. The support plate has a perimeter approximately equal to an inside perimeter of combustor housing which allow the support plate to limit the movement and vibration of the fuel nozzles.

The device as claimed in claim 10, wherein the relatively smaller part stream is about 20-40% of the mass stream of the delivered air. 12. The device as claimed in claim 10, wherein the booster is coupled to the ejector via a line, to which a buffer tank is coupled for smoothing of pressure fluctuations. 13. The device as claimed in claim 10, wherein the output of the ejector is coupled to at least one of a device for pressure-type fluidized-bed firing, an after burner and a coal gasifier. 14. A power station, including the device as claimed in claim 10. 15. The device of claim 11, wherein the booster is connected to the ejector via a line to which a buffer tank is connected for smoothing of pressure fluctuations. 16. The device as claimed in claim 11, wherein the relatively smaller part stream is about 20% of the mass stream of the delivered air. 17. The method as claimed in claim 11, wherein the relatively smaller part stream is about 20-40% of the mass stream of the delivered gas. 18. The device as claimed in claim 11, wherein the output of the ejector is coupled to at least one of a device for pressure-type fluidized-bed firing, an after burner and a coal gasifier. 19. The device as claimed in claim 12, wherein the output of the ejector is coupled to at least one of a device for pressure-type fluidized-bed firing, an after burner and a coal gasifier. 20. A power station, including the device as claimed in claim 10, and further including a device for pressure-type fluidized-bed firing and a coal gasifier.
