WATER VAPOR CONDENSING DEVICE USING AERATION TYPE CONDENSER HAVING FREEZING PROTECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To keep a back-pressure for a turbine in a low pressure and enable a freezing protective characteristic to a collected condensate to be attained. SOLUTION: Non-condensing gas is continuously purged out of an inner part of a row of pipes in a primary condenser 72, and then pressures at a common lower discharging header 82 are made uniform through the purging operation. Vapor 88 and non-condensing gas 94 flowed from the primary condenser 72 ascend in a pipe 96 and then they are sent to an aeration type condenser 92. The aeration type condenser 92 is protected against freezing by laminating up separately individual row of pipes within flow modules 98 of the condenser. Within the aeration type condenser 92, reoriented water vapor 88 and generated condensate 100 fall from an upper region of the aeration type condenser 92 while being flowed in a parallel state.
