ABSTRACT:
An axial-flow turbine which is driven by a working fluid which contains dust and moisture is disclosed. The turbine has stator blade means and rotor blade means, and a working fluid exit angle of a first-stage stator blade means is smaller than that of the second-stage stator blade, wherein the absolute exit velocity of the working fluid from the first stage stator blade means is smaller than that of the second stage stator blade means, whereby the flow of the working fluid has the same directional vortical flow with the turbine shaft as the axis of the vortex and dust fouling is checked particularly in connection with the first-stage stator blade means.
