Filed:

Jul 3, 2002

Appl. No.:

10/190285

Inventors:

Joe Ingram - Palm Beach Gardens FL, US

International Classification:

F23R003/04

US Classification:

060/804000, 060/752000

Abstract:

Air tubes are circumferentially spaced around the outer liner of an annular combustor for a microturbine engine in proximity to and downstream of a dam extending into the combustion chamber for reducing the emission of NO. The air tubes are dimensioned so that the length to passage diameter is such that a swirling motion of the air injected into the combustion zone is normal to the center line of the annular combustor.

International Classification:

F23R003/28

US Classification:

060/740000, 060/752000

Abstract:

A splashplate dish or disc shaped having a contoured face is inserted in and recessed from the top of the air tube feeding the combustor of a microturbine with a mixture of air and fuel. The splashplate permits the use of a single orifice fuel nozzle or injector to replace a multi orifice injector. The splashplate includes contoured segments circumferentially disposed around the face of the splashplate for splitting the fuel into discrete streams for mixing with the air admitted into the air tube. In one embodiment the splashplate includes radial slots circumferentially spaced around the face of the splashplate for directing the fuel directly into the air tube through the slots. In another embodiment a dimple or depression is located centrally of the splashplate where the fuel impinges before being dispersed in the plurality of streams. Attachment means are provided for centering and recessing the splashplate in the air tube.
