Abstract
A steam turbine direct contact condenser prevents cooling water sprayed from spray nozzles from reaching turbine blades of an axial-flow turbine, while introducing turbine exhaust gases exhausted by a steam turbine in the horizontal direction to cool such gases. The condenser includes an exhaust gas inlet part that introduces the turbine exhaust gases containing steam of the steam turbine and non-condensable gases in the horizontal direction, a steam cooling chamber that sprays cooling water to the introduced turbine exhaust gases to cool them, and a water storage disposed at the bottom of the steam cooling chamber that stores condensed water cooled from the steam and the cooling water. The steam cooling chamber includes a first cooling water spraying mechanism and a second cooling water spraying mechanism.
