Abstract
An exhaust device for a condensable-fluid axial-flow turbine, comprising an annular diffuser with an axial input situated at the output of the last stage of the turbine and a substantially radial output leading to a condenser which is divided into two zones, in one of which the pressure is lower than in the other, the outer wall of the diffuser with respect to the input flow into the duct having a circumferential suction slot which removes a fraction of the flow in the diffuser towards the lower-pressure part of the condenser, said wall further having a shape such that the pressure gradient measured at its surface in the flow direction is negative or zero at all points.
