Title:
GAS TURBINE COMBUSTOR AND GAS TURBINE ENGINE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2015/046097
Kind Code:
A1
Abstract:
In order to prevent combustion vibration in a gas turbine combustor using a liquid fuel by means of a simple configuration having high cost performance, this gas turbine combustor (1) is equipped with a pilot burner (3) arranged in the central portion of a combustion tube (2), and multiple main burners (4) arranged so as to surround the pilot burner. The main burners (4) are configured such that a main nozzle (11) is installed in the central portion of a cylindrical premixing nozzle (12), with a liquid fuel (F2) being sprayed from fuel spray holes (15) (provided at the periphery of the main nozzle (11)) toward the inner surface (13a) of an elongated nozzle (13) connected to the downstream side of the premixing nozzle (12), and with the spray pattern of the fuel being set so as to differ among the multiple main burners (4). For example, different spray patterns can be provided by setting different liquid fuel (F2) spray angles (θ1, θ2) for the fuel spray holes (15) of the multiple main burners (4).
