Direct contact condenser for steam turbine

摘要

Improvements to a direct contact condenser which can prevent cooling water sprayed from spray nozzles from reaching the turbine blades of an axial-flow turbine which can damage the turbine blade. Direct contact condenser consists of three major sections which are attached directly to the turbine; an exhaust gas inlet part (11); a steam cooling chamber (12); and a water storage part (13). The steam cooling chamber includes a first cooling water spraying mechanism (21) which sprays the cooling water from a perpendicular to a downstream direction which prevents water on the blades of the turbine; a second cooling water spraying mechanism (30) which sprays in all directions; and a non-condensable gas chamber.
