DIRECT CONTACT TYPE CONDENSER FOR STEAM TURBINE

WIPO Patent Application WO/2013/008477

A1

Provided is a direct contact type condenser for a steam turbine, the direct contact type condenser into which turbine exhaust gas horizontally discharged from the steam turbine is horizontally introduced and which can prevent cooling water that is sprayed from a spray nozzle while cooling the turbine exhaust gas from arriving at turbine blades of an axial flow turbine. A direct contact type condenser for a steam turbine is provided with: an exhaust gas introduction unit (11) into which turbine exhaust gas containing steam and noncondensing gas from the steam turbine is horizontally introduced; a steam cooling chamber (12) which cools the introduced turbine exhaust gas by spraying cooling water thereto; and a water accumulation unit (13) which is disposed under the steam cooling chamber and accumulates condensed water cooled from the steam and the cooling water. The steam cooling chamber is provided with: a first cooling water spray mechanism (21) which is provided on the exhaust gas introduction unit side and sprays the cooling water in a spray region ranging from the side thereof in the downstream direction of the turbine exhaust gas; and a second cooling water spray mechanism (30) which is provided on the downstream side from the first cooling water spray mechanism and sprays the cooling water to the turbine exhaust gas in all directions.
