电厂锅炉若干重要在线自动测量技术

Several Important On-line Measurement Techniques of Boilers of Fired Power Plants

讨论了火力发电厂锅炉运行优化与控制中的若干重要在线自动测量技术,如火燃温度与温度场的测量,粉煤浓度、速度及质量流量等参数的测量,以及这些参数测量对我国经济发展及环境保护方面的重要性,认为火力发电厂主体设备 燃煤锅炉的优化运行与控制一直是一大难题,其根本原因在于缺乏实时监测锅炉运行状态的测量技术及仪表。

Some important online measurement techniques were summarized and discussed for optimizing and controlling coalfired boilers e.g., the measurement of temperature and its distribution, the measurement of density ,velocity and mass flow of pulverized coal , and their importance to the economy development and environment protection of our country It is concluded that the optimization operation and control of coalfired boilers in fired power plats is a key difficulty and its ultimate reason is that lacking of measure technology and instrument.
