PROCESS AND INSTALLATION FOR COOLING THE VACUUM MAINTAINING ASSEMBLY, WITH EJECTORS, OF THE STEAM TURBINE CONDENSER

摘要

the refers to a process and a plant for cooling support assembly with vacuum ejectors, condenser, steam turbine, used in thermoelectric power plants.the process according to the invention realizes the cooling with a cooling agent composed of water taken from amontele circuit of turbine condenser cooling water, which is taken from a circulation pump and then is only through the capacitor first steps last compresi when the condenser is in the other, the turbine operates with lower efficiency than the dimensioning,stay with the condensation and the other main coolant, or through the maintenance of vacuum capacitors, when the capacitor has a function with a turbine efficiency lower than the sensitive dimensioning, after which the cooling water is returned downstream the circuit of the condenser cooling water turbine, and the main condensation, when used,bring in the regenerative preheating of the low pressure.the installation according to the invention, in which the process is applied, consisting of a pipe (1) which takes the cooling water from the cooling water circuit of a capacitor (2), and a circulation pump (4) for passing cooling water through another condenser (5) of pr imei steps of compression of an assembly (6) for maintaining vacuum, the capacitors (7 and 8),through the operation of a vane (9) are cooled with the main condensate, after which, through a duct (10), the cooling water is introduced into the exit of cooling water of condenser (2), and the main condensation
