Chemistry control system for power plant

A chemistry control system for a power plant includes at least one sensor (15) of an electrochemical indicator for a coolant, said sensor being electrically connected to a unit (21) for processing andtransmitting measurement data, an outlet of said unit being connected to a central electronic computing machine (22) which controls actuators (23), (24) for injecting hydrogen and chemical reagents.The sensor (15) is a flow-through sensor; a hydraulic inlet of the sensor is attached via a pipe (13) for collecting samples to a process loop of the power plant, and a hydraulic outlet of the sensor(15) is hydraulically successively connected to a first heat exchanger (17) and a first throttling device (18), which is equipped with a reverse loop (19) for supplying coolant. 动力装置的化学控制系统包括至少个载热体的电化学指数传感器(15)，其电连接到测量数据处理和传输单元(21)，其输出端连接到中央电子计算机(22)，中央电子计算机(22)控制引入氢和化学试剂的执行器(23)，(24)。传感器(15)由通过采样管(13)连接到动力装置的处理回路的流动液压入口制成，传感器(15)的液压输出与第热交换器(17)和设有可逆载热体供应回路(19)的第节流装置(18)串联地液压连接。
