摘　　要：在热采锅炉运行中干度是一个重要参数,其精确程度影响着热采锅炉运行的安全性和热力采油的效果。在水/蒸汽两相流的动态监测技术的基础上,开发出了干度微机测控技术,用压差节流装置测湿蒸汽的干度与流量等参数,配合温度、压力传感器便可以自动检测热采锅炉的运行情况,同时可以通过信号前馈和反馈控制锅炉给水量和风量,实现热采锅炉自动安全运行。Thermal recovery boiler operation dryness is an important parameter, which affects the accuracy of thermal recovery boiler operation safety and the effect of heating oil recovery. Based on the water / steam dual phase flow dynamic monitoring techniques, it developed dry degree microcomputer measurement and control technology that was to use differential throttling device measuring degree of wet and dry steam flow, and other parameters, the temperature and pressure sensors will be able to automatically detect thermal recovery boiler operation, While the boiler, through the feedback control signal, was able to control the amount of water and wind to achieve the sate operation of thermal recovery boiler automatically.
