Abstract: A steam conditioning system for discharging bypass steam into a condenser of a steam powered generating plant and other uses. The system includes a steam conditioning device comprising an inner evaporative core and an outer shell. The core may be formed of a tubular piping section disposed at least partially inside the outer shell forming an annular space therebetween. An inlet end of the core receives steam from a piping header fluidly connected to an upstream desuperheating pressure reducing station which injects liquid coolant into the steam stream. Steam discharges through the core outlet end into the outer shell, reverses direction, and flows into the condenser. In one embodiment, the steam conditioning device may be disposed inside the dome of the condenser except for the inlet end. The device intends to increase flow residence time to evaporate entrained carryover coolant droplets in the incoming steam before release to the condenser.
