针对山西阳泉第二发电厂300MW机纽W型火焰锅炉存在的过热器超温，飞灰含碳量高、站渣等问题，进行了以二次风配试验为主末内容不得的锅炉燃烧调节器整，通过在不同工况下检测炉内火焰温度分布等锅炉运行参数，分析了各主要二次风对锅炉内燃烧工部的影响及其调节规律，并讨论了锅炉负荷变化时对炉内温度分布配风的影响。

The evolution of the suface waves for vertical free-falling films with Reynolds number ranging from 400to 5,100 was measured using multiple-point conint conductance sensors and a computer-based data acquisition system. The Physieal and mathematieal models describing the free-falling turbulent wavy films with the free surface boundary are presented. The governing equations are solved numerically in the film waves based on the coordinate transformation of the measured time-dependent film thickess data. The results show that the evolution of the surface waves has a remarkably nonlinear nature. The hydyrodnamics and velocity profiles at the wave front, the wave crest, and the wave back for the soliary waves indicate significant effects of the soliary surface waves with interior reeirculation flow on heat and mass transfer enhancement. A correlation for an average heat transfer coefficient is proposed as a function of the Reynolds and Prandtl numbers based on the measurements.

以烟煤和褐煤混煤的超细煤粉件为再燃燃料，用N2、O2、CO2、NO配制模拟烟气，在立式携带流反应器巾进行了煤粉再燃还原NO的实验，研究了超细煤粉的细度对炉内1300℃高温烟气中再燃还原NO的影响。结果表明：①超细煤粉在再燃区内最佳停留时间约为0.8s：②NO的还原效率随着超细煤粉细度提高而增大；③在再能燃料比为20%～25%、再燃区的初始氧浓度为4%～6%的工况范围内，煤粉细度对NO还原效率的影响显著；④在保证一定的NO捧放浓度水平的情况下，使用较细的超细煤粉作为再燃燃料时，可以减少再燃燃料的投入量。

电站锅炉煤粉燃烧过程中，煤粉着火前期的升温速率可达104K/s。而且煤粉在着火前期的升温状态直接影响到煤粉挥发份的释放速度和挥发份成分，进而影响到煤粉颗粒的着火和燃烧。该文针对开煤颗粒快速升温过程中非傅立叶导热效应，利用热波模型D-P-L模型对快速升温过程中煤颗粒的温度场时行的数值模拟，与实测结果进行了比较。并发现对于电站锅炉所燃用煤粉的粒径范围，在煤粉着落火前的升温过程中考虑非傅立叶导热应是十分必要的。
