- 摘要：以激光为光源、由计算机操纵和控制的光散射法具有实时快速、非接触、在线、无需取样和连续测量的优点,能直接给出烟尘和粉尘的排放浓度和粒径大小.在一台工业锅炉高温烟气中对烟尘排放浓度和粒径大小的现场热态实测结果表明,测量结果是准确和可靠的.
- Abstract：Based on the light scattering technique, an optical method is presented, which is distinguished by real time, fast, non contact, in situ and continuous measurement, and is able to give directly the mass concentration in mg/m3 and particle size of the smoke and dust. Experimental studies show that the basic principle of this method is correct and the measurements are accurate. The results of measurements made in the stack of an industrial boiler are also given.
