Gas turbine combustor injection assembly, and combustor fuel mixture feed method

摘要

A fuel mixture is fed to a gas turbine combustor (1) by an injection assembly (3), which has an outer body (10) with combustion-supporting air inlets (15a)(16a); a conical tubular portion (22) housed inside the outer body (10) and partly defining an inner conduit (26) and an outer annular conduit (27); and a first (29) and second (30) feed circuit for feeding liquid fuel to the inner conduit (26) and outer annular conduit (27) respectively; the first circuit (29) having a ring (35) of conduits (36) with respective axes (36a) parallel to a generating line (24) of an outer surface (23) of the conical tubular portion (22).
