为解决直接测量电厂锅炉炉膛燃烧层温度困难的问题，开发了炉膛层温红外测温系统，并在国内某660 MW超临界机组电厂锅炉上安装并运行。采用该系统可以直接、快速、连续地测量炉膛各燃烧层实时温度，实现了炉膛燃烧状态监测点的前移。基于炉膛各燃烧层温度数据，开展机组超低负荷燃烧适应性测试，最低负荷达到127 MW，达到了额定负荷的19.2%，与未采用该系统的同类电厂相比，每年节省燃油量约60%。

In order to solve the difficult problem of directly measuring the temperature of each combustion layer in the boiler furnace of power plant,the infrared temperature measuring system of furnace layer temperature has been developed and installed and operated in a domestic 660 MW supercritical unit boiler.With this system,the real-time temperature of each combustion layer in the furnace can be measured directly,quickly and continuously,and the forward movement of the monitoring point of the furnace combustion state can be realized.Based on the temperature data of various combustion layers in the furnace,the adaptability of ultra-low load combustion of the unitis tested,and the minimum load reaches 127 MW,which is 19.2% of the rated load.It saves about 60 percent of the fuel each year,compared to similar power plants without the proposed system.
