基于维恩位移定律和普朗克定理，提出了根据光纤光谱仪测得的相对火焰辐射光谱快速确定煤粉炉火焰温度的峰值波长法，研究了煤粉炉火焰中辐射率函数对该方法测量温度的影响，并以300MW和350MW煤粉炉火焰辐射光谱为基础，给出了适用于电站煤粉炉火焰温度光谱法测量的峰值波长温度测量公式．结果表明：对于煤粉炉火焰这类非灰体温度火焰，利用峰值波长法可以快速得到火焰温度，且最大测量误差小于1．60％．

英文摘要：

Based on Wien＇s displacement law and Planck＇s law, a fast measurement technique, the method of peak wavelength, was presented for directly determining the flame temperature of pulverized coal-fired boiler according to the relative spectrum of coal flame measured by fiber optic spectrometer, so as to study the effects of flame emissivity function on the temperature measurement. Taking two boilers respectively of 300 MW and 350 MW as objects of study, specific formulae of peak wavelength were proposed for meas- urement of the flame temperature. Results show that the peak wavelength method can be used for fast measurement of the non-gray flame like the flame in pulverized coal-fired boiler, with maximum measure- ment error less than 1.60 %.
