Abstract (en)
[origin: WO2011092779A1] Disclosed is a gas turbine combustor (1) equipped with a fuel injection valve (13) that injects fuel (F) towards a combustion chamber (11), a swirler (14) that, in the vicinity of the fuel injection valve (13), takes in and circulates compressed air (CA) that was generated by a compressor, a cylindrical guide body (34) that guides the compressed air (CA) taken in from the swirler (14) to the combustion chamber (11), and a heat shield (23) having a cylinder section (23b) that is positioned farther on the periphery than the guide body (34). A purge hole (40) is formed in the cylinder section (23b). Air is introduced from the purge hole (40), and said air is supplied to a space (39) formed between the guide body (34) and the cylinder section (23b).
