MULTISTAGE PRESSURE CONDENSER AND STEAM TURBINE PLANT PROVIDED WITH SAME

Document Type and Number:

WIPO Patent Application WO/2013/080950

Kind Code:

A1

Abstract:

This multistage pressure condenser is provided with: a high-pressure chamber and a low-pressure chamber; a pressure partition wall for partitioning the interior of the low-pressure chamber into an upper section and a lower section, a porous plate being mounted to the pressure partition wall; a cooling pipe group provided to the upper section of the low-pressure chamber, low-pressure-side steam being condensed into low-pressure-side condensate by the cooling pipe group; a reheating chamber for storing the low-pressure-side condensate flowing down through the porous plate, the reheating chamber being located in the lower section of the low-pressure chamber; a high-pressure-side steam introduction means for introducing high-pressure-side steam in the high-pressure chamber into the reheating chamber; a liquid-film-forming means provided on the flow path of the high-pressure-side steam, the liquid-film-forming means guiding, to the reheating chamber, the low-pressure-side condensate flowing down through the porous plate while causing the low-pressure-side condensate to disperse on the surface; and a ventilation means for promoting the flow of the high-pressure-side steam.
