The invention consists a dual section vessel including a first section being a turbine exhaust steam enclosure and a second section being a condensate water vessel accumulation, both sections being connected by a system of water columns. The system of water columns comprising moderate diffusers for retaining turbine exhaust steam velocity without increasing in pressure, towards impact with cold recirculated condensate water. The recirculated warm condensate water from the condensate water vessel flows through a counter current heat exchanger, and as cold condensate water to dispersion pipes connected to the ends of the diffusers. This complete system is arranged for receiving, compressing and condensing the exhaust steam from the turbine last stage. From the collision location the exhaust steam and condensate water continue to flow as "two phase flow" downward to the "condensate water vessel." In the water columns the continuous flow produces a lower pressure in the top of the column than the pressure in the bottom. The inclusion of a "counter current heat exchanger" assures a very low difference between the cooling media inlet temperature and the exiting recirculated condensate water, and a correspondingly significant reduction of the turbine exhaust steam temperature.
