| 摘 要： | 为解决锅炉尾部烟道中烟气气流分布不均匀性问题,在锅炉转向室内增设烟气调节屏,并通过数值计算和采用粒子图像测速仪（PIV）测量的方法对烟气调节屏的调节性能进行优化.在锅炉转向室内优化设计出3种不同的烟气调节屏装置,并引用不均匀系数和速度偏差系数定量评定烟道内流场的均匀性,结果显示增设烟气调节装置后气流场均匀程度明显变优....

| Abstract: | Numerical simulation and particle image velocimetry(PIV) were used to solve the uneven distribution of the flue gas flow in the rear flue.Three type of gas adjust-screen were designed and two assessment indicators,non-uniform coefficient and velocity deviation,were introduced to describe the quantitative assessment of the flue gas flow field uniformity.Variation of two-parameter were observed before and after joining adjustment screen to the flow field.It is shown that the distribution of flow field get bet... |
