本文介绍了应用新研制成功的“二维可辨流向的激光多普勒测速仪”,对UP直流锅炉设计方案水模流场进行的定量测量.还对同一截面在改进折焰角结构前后,作了对比测量,为改进设计提供了依据.激光测速与水模试验的结合,使水模试验既保持了流速较低便于观察和流动形象真实直观的特色,又将水模技术由只能定性观察分析,向前推进到定性、定量全面分析的新阶段.为锅炉研究、设计开创了一条新途径.
This paper introduces the quantitative measurement of water flow field in a UP direct-flow boiler by using the newly developed “two-dimensional discernable flow direction laser Doppler velocimeter.” In the same section before and after the improvement of the flaring angle structure, Made a contrast measurement to provide a basis for improving the design.Laser speed measurement and the combination of water-based test, the water-based test not only to maintain the flow rate is low and easy to observe and visual image of the flow of real features, but also water-based technology can only qualitative Observe and analyze and push forward to a new stage of qualitative and quantitative comprehensive analysis, which opens up a new way for boiler research and design.
