A multi-stage, wet steam turbine employs working fluid, such as steam for example, in its two-phase region with vapor and liquid occurring simultaneously for at least part of the cycle, in particular the nozzle expansion. A smaller number of stages than usual is made possible, and the turbine may handle liquid only. Simple construction, low fuel consumption and high reliability are achieved.

In a turbine, the combination comprising (a) first nozzle means to which wet steam is supplied for expansion in the nozzle means, (b) a turbine rotor having first vanes to receive and pass water supplied via the nozzle means and forming a ring of water proximate said first vanes, the rotor also having second vanes to which steam is supplied via the nozzle means, (c) rotary means to receive feed water and to pressurize same, and (d) a recuperative zone communicating with said rotary means and with said second vanes to receive the pressurized feed water and the steam that has passed said second vanes for fluid mixing in said zone and for enabling direct heat exchange from the steam to the feed water, the fluid mix in said zone being withdrawn for heating and supply to said first nozzle means as wet steam.
