Title:
DEVICE FOR STABILIZING COMBUSTION IN GAS TURBINE ENGINES
Document Type and Number:
WIPO Patent Application WO2005040682
Kind Code:
A3
Abstract:
A burner (100) for a gas turbine combustor that uses a central bluff body flame holder (20)and a quarl (80) to shape the recirculation zone in order to stabilize the combustion process. The burner includes, among other elements, a cylindrical main body (50) and a flame holder. The flame holder is disposed within a fuel-air mixing chamber (60) and includes a base portion (22) and an elongated bluff body (24). The base portion engages with the main body of the burner in a supporting manner and the elongated bluff body extends in an axially downstream direction from the base portion through the internal mixing chamber so as to position a combustion ignition point downstream of the internal mixing chamber. The quarl device defines an interior recirculation chamber (82) and a burner exit (84).
