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. ## Claims ### Claim 1 A direct contact condenser for a steam turbine, the direct contact condenser comprising: an exhaust gas inlet part configured to introduce a turbine exhaust gas containing steam and a non-condensable gas of the steam turbine in a horizontal direction; a steam cooling chamber configured to spray cooling water at the turbine exhaust gas introduced through the exhaust gas inlet part to cool the turbine exhaust gas; and a water storage which is disposed at a bottom of the steam cooling chamber and which stores condensed water generated by cooling the steam and the cooling water, the steam cooling chamber comprising: a first cooling water spraying mechanism which is disposed adjacent the exhaust gas inlet part and which sprays the cooling water within a range restricted from a side of the condenser to a downstream direction of the turbine exhaust gas; and a second cooling water spraying mechanism which is disposed at a downstream side of the first cooling water spraying mechanism and which sprays the cooling water to the turbine exhaust gas in all directions. ### Claim 2 (depends on 1) The steam turbine direct contact condenser according to claim 1, wherein the first cooling water spraying mechanism comprises a plurality of cooling water spray pipings extending in a direction orthogonal to a guiding direction of the turbine exhaust gas, in communication with a cooling water supply piping, and each formed with a plurality of spray nozzles in a lengthwise direction. ### Claim 3 (depends on 2) The steam turbine direct contact condenser according to claim 2, wherein the first cooling water spraying mechanism comprises: a coupling piping configured to couple adjoining cooling water spray pipings in parallel with the turbine exhaust gas in a flow path of the turbine exhaust gas; and a plurality of spray nozzles formed on a bottom side of the coupling piping. ### Claim 4 (depends on 3) The steam turbine direct contact condenser according to claim 3, wherein the plurality of spray nozzles spray the cooling water in at least one of a downward direction or an obliquely downstream side. ### Claim 5 (depends on 1) The steam turbine direct contact condenser according to claim 1, wherein the second cooling water spraying mechanism comprises a plurality of cooling water spray pipings extending in a direction orthogonal to a guided direction of the turbine exhaust gas, in communication with a cooling water supply piping, and each formed with a plurality of spray nozzles in a lengthwise direction. ### Claim 6 (depends on 1) The steam turbine direct contact condenser according to claim 1, further comprising: a gas cooling chamber which is formed at least either one of a downstream side or a side of the second cooling water spraying mechanism, and which causes a non-condensable gas remaining in the turbine exhaust gas to which the cooling water is sprayed to flow, and wherein the gas cooling chamber comprises a plurality of third cooling water spraying mechanisms which are formed in communication at either one of the downstream side and or the side of the second cooling water spraying mechanism, and which spray the cooling water to the non-condensable gas remaining in the turbine exhaust gas. ### Claim 7 (depends on 6) The steam turbine direct contact condenser according to claim 6, further comprising: a partition plate having an opened bottom and disposed between the second cooling water spraying mechanism and the plurality of third cooling water spraying mechanisms. ### Claim 8 (depends on 1) The steam turbine direct contact condenser according to claim 1, wherein the water storage is provided with a connection port at a bottom of the water storage connected to a condensate pump, controls a water level between a normal operation water level where the connection port is completely below the water level and a maximum operation water level higher than the normal operation water level during a successive operation of the condensate pump, and has a water storage capacity set in such a way that the water level does not exceed an abnormal maximum water level lower than a bottom of the exhaust gas inlet part even if the water level exceeds the maximum operation water level due to a raise in the water level by remaining cooling water when the condensate pump abnormally stops.
