Abstract

There is provided an axial flow turbine 12 capable of realizing a reduction in gland seal leakage amount. The axial flow turbine 12 is of a single flow type and includes an upstream-side gland seal packing G1 located on an upstream side of a working medium in an axial direction of a turbine rotor 20 and a downstream-side gland seal packing G2 located on a downstream side of the working medium in the axial direction of the turbine rotor 12. The axial flow turbine 12 is configured such that a cooling medium CF leaking between the turbine rotor 20 and the downstream-side gland seal packing G1, lower in temperature and higher in pressure than the working medium F is extracted between adjacent seals 35b of the upstream-side gland seal packing G1, and the extracted cooling medium is introduced via an extraction pipe T1 into the stationary blades 41.
