Title:
COMBUSTOR PANEL, COMBUSTOR, COMBUSTION DEVICE, GAS TURBINE, AND COMBUSTOR PANEL COOLING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/154729
Kind Code:
A1
Abstract:
In the present invention multiple cooling flow paths (35) are formed between the outer surface and the inner surface of a combustor panel. The cooling flow paths (35) have inlets (36i) that open at the outer surface and introduce a cooling medium into their interior, and outlets (36o) that open at the inner surface and discharge the cooling medium flowing through their interior. Among the multiple cooling flow paths (35), each of multiple cooling flow paths (35) extending from a position along the edge of an outlet (37) of the combustor panel forms an aperture-vicinity flow path (35a). Among the multiple aperture-vicinity flow paths (35a), each of the aperture-vicinity flow paths (35a) for which the inlet (36i) is formed closer to the aperture (37) than the outlet (36o) forms an aperture-side inlet flow path (35ai). The number of the aperture-side inlet flow paths (35ai) is greater than one-half the number of the all of the aperture-vicinity flow paths (35i).
