Diode laser-based two-line atomic fluorescence (TLAF) thermometry applied to flames of combusting wood pellets is demonstrated. The temperature above burning wood pellets placed in the hot product gas of gallium seeded laminar flames is measured. The calibration-free technique provides spatially resolved temperatures in one dimension with sufficient temporal resolution to resolve all combustion stages of a pellet, even in highly sooting flames. The temperature above a burning pellet was found to decrease due to the release of volatile gases and the accuracy and precision of the technique is assessed at flame temperatures.
二极管激光双谱线原子荧光（TLAF）测温技术应用于燃烧木屑颗粒的火焰中。测量了放置在掺镓层流火焰热产物气体中的燃烧木屑颗粒上方的温度。该无校准技术提供了一维空间分辨温度，具有足够的时间分辨率，可以分辨颗粒的所有燃烧阶段，即使在高度发烟的火焰中也是如此。发现由于挥发性气体的释放，燃烧颗粒上方的温度降低，并且在火焰温度下评估了该技术的准确性和精密度。
