Gas turbine combustor equipped with heat-transfer device

摘要

An object of the present invention is to provide a gas turbine combustor that can suppress an increase in pressure loss while improving product reliability. The gas turbine combustor includes a combustor liner (1), an air transfer casing (2) installed on the outer circumference of the combustor liner (1), the combustor liner (1) and the air transfer casing (2) defining an annular passage therebetween adapted to allow a heattransfer medium to flow therethrough, and a plurality of vortex generating devices (10) disposed on an inside surface of the air transfer casing, the vortex generating devices (10) generating longitudinal vortices each having a rotational axis extending in a flow direction of a heattransfer medium. The plurality of vortex generating devices (10) are arranged in paired manner, each pair of devices generating vortices having rotational directions opposed to each other.
