Abstract

The invention belongs to the technical field of thermotechnical measurement, in particular relates to a system and a method for measuring steam humidity of a steam generator and aims to provide the system and the method for measuring the steam humidity of the steam generator to make up defects of a conventional measurement technique, and measure the steam humidity of the steam generator in real time, the results are accurate and reliable, and the system is applicable to different flow measurement ranges. The system is characterized by comprising a dryer lyophobic flow measurement module and adeck lyophobic flow measurement module, wherein the dryer lyophobic flow measurement module and the deck lyophobic flow measurement module are respectively connected with both sides of the steam generator through pipelines. The system is capable of achieving real-time measurement for steam humidity measurement on the steam generator, has high measurement precision, is applicable to different lyophobic flow ranges, and is small in energy loss and safe and automatic.

Description

technical field [0001] The invention belongs to the technical field of thermal measurement, and in particular relates to a steam generator steam humidity measurement system and method. Background technique [0002] Wet steam widely exists in the steam generator, and the steam humidity is less than 0.1% before it is allowed to enter the steam turbine to work. Therefore, steam humidity measurement in steam generators has always been a key issue in steam generator design, experimental research, and engineering applications. Measuring and monitoring the steam humidity at the outlet of the steam-water separator and dryer can obtain the steam-water separation performance of the two key components, providing a basis for design improvement and engineering verification; monitoring and measuring the steam humidity at the outlet of the steam generator can provide a basis for the design improvement of the steam generator, Provide sufficient arguments for engineering verification and sa...
