Steam conditioning system

摘要

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.

1. A steam conditioning system comprising:
a condenser defining an interior region; a steam conditioning device comprising an assembly of:
an inner evaporative core comprising a tubular section defining a longitudinal axis, the tubular section including an inlet end configured for coupling to a steam piping header and a terminal outlet end; andan outer shell formed around the inner evaporative core, the outer shell including a first head, an opposing closed second head, cylindrical sidewalls extending between the first and second heads, and an internal cavity receiving the inner evaporative core at least partially therein through the first head; a longitudinally extending annular space formed between the inner core and outer shell; wherein the outer shell is in fluid communication with the condenser and arranged to receive steam from the inner core and discharge the steam into the interior region of the condenser.
