水煤膏冷态雾化试验装置和测量系统的研究

The Study of a Cold-state Atomization Test Rig and a Measurement System for Coal-water Paste

建立了一套垂直式水煤膏雾化试验装置 ,提出了通过采用PIV技术及二次开发的图像处理软件来测量水煤膏雾化颗粒的平均粒径与分布的方法 ,分析了水煤膏雾化颗粒测量的影响因素 。

A vertical test rig for the atomization study of coal-water paste has been set up and a method proposed for measuring the particle average diameter and distribution of water coal paste atomized particles with the use of a PIV (particle image velocimetry) technique and a newly developed image processing software. All factors, which may have an impact on the measurement of the coal water paste atomized particles, are analyzed, creating a solid basis for the further research of the nozzle atomization properties of the coal water paste.
