CONNECTING PLANT OF NUCLEAR POWER INSTALLATION AND SEA WATER DESALTING APPARATUS

摘要

PURPOSE:To positively maintain the operation of a steam valve, by a method wherein a control system for controlling the load variation of a heat utilizing system is divided into two and the control system in a conventional heat utilizing system is directly adapted to one divided section while a independent control system in a heat generating system is newly provided to the other divided section. CONSTITUTION:An intermediate indirect heat exchanger 3 and a flash tank 6 are provided between the steam extraction part 1a of a nuclear power installation and the brine heater 9 of a sea water desalting apparatus and the pipe outside of the intermediate indirect heat exchanger 3 is communicated with the side of the intermediate nuclear power installation while the pipe inside thereof is connected to the side of a brine heater 9 by an intermediate heating medium pipeline 12. To a recirculation steam arranged pipe system 8 connecting the flash tank 6 and the brine heater 9, a heat transfer system A provided with a flow control valve 15 for making an outlet temp. constant on the basis of the outlet temp. of the brine heater 9 is provided and an extraction flow control valve 6 for controlling a steam extracting amount on the basis of internal pressure is provided between the steam extraction part 1a and the intermediate indirect heat exchanger 3 so as to make the internal pressure of the flash tank 6 constant.
