Filed:

Apr 12, 2006

Appl. No.:

11/279513

Inventors:

Gerald Elliott - Marietta GA, US
Carl Linderoth - Norcross GA, US
Clifford McConnell - Birmingham AL, US
Alvin Short - Waleska GA, US

Assignee:

Zilkha Biomass Energy LLC - Houston TX

International Classification:

F02G 3/00

US Classification:

060722000, 110229000

Abstract:

A cyclonic combustor comprising a combustion liner forming a combustion chamber having a generally cylindrical shape, a biomass feed inlet for receiving biomass particles under pressure, wherein the biomass feed inlet is formed so that the biomass particles are introduced into the ignition zone of the combustion chamber with a tangential component relative to the longitudinal axis of the combustion liner, and a plurality of air tuyeres formed through the combustion liner for receiving compressed air, wherein the plurality of air tuyeres are arranged to introduce the compressed air into the combustion chamber with a tangential component relative to the longitudinal axis of the combustion liner. A direct-fired biomass-fueled pressurized gas turbine system comprising a pressurized feed system, the cyclonic combustor, and a gas turbine. Methods of operating a cyclonic combustor and methods for direct firing a gas turbine.
