新型固定式电站锅炉空气预热器热点检测系统

A New Fixed Hot Spots Detection System of Power Plant Boiler Air Preheater

针对移动式空气预热器热点检测系统机构易"卡死"、热点检测严重滞后等问题,利用红外阵列传感器具有较宽测量范围的特点,设计了一种固定式热点检测方案。基于红外阵列传感器,设计了基于Dempster-Shafer(DS)证据理论的热点判断方法。

With the aim of such problems as the ＂clogging＂ and serious delay of hot spot detection in the mobile hot spot detection system mechanism of air preheater,a new fixed hot spot detection system by means of infrared array sensor with a wide measuring range is proposed in this paper.According to the infrared array sensor features,a hot spot detection method based on Dempster-Shafer（DS） evidence theory is designed.
