摘　　要：利用可调谐半导体激光吸收光谱(TDLAS)技术在电站锅炉尾部烟道进行测量或者采取抽取式的测量方法,能够在一定程度上反映锅炉的燃烧状况,但并不直接、迅速,需要建立模型根据测量结果对炉膛内的燃烧状况进行计算。为了给燃烧诊断提供更直接的参考,需要对锅炉炉膛进行直接测量。选择1.3μm附近的一对H2O谱线,设计了一套测量系统,实现了TDLAS技术对燃煤电站锅炉炉膛温度的直接测量。对电站锅炉起机过程进行温度测量试验,为研究锅炉炉膛的非接触式原位在线测量系统,并进一步研究燃烧优化提供了支持。Application of tunable diode absorption spectruscopy(TDLAS)to power plant FG tail duct or extraction measurement could reflect the combustion condition to some extent.But it is not a direct and rapid method.To support the diagnose the combustion process more directly,this present paper designed a combust TDLAS sensor to measure the coal-fired power plant using apair of H2O transitions near 1.3μm.The temperature was measured during the whole starting process of the power plant,which is a support for developping non-intrusive in-situ measurement system and combustion controll.
