火电厂灰斗积灰物性参数(安息角、水分)对颗粒流动性的影响机制及实验验证OA

Based on the theory of particle mechanics,this paper analyzes the correlation between the angle of repose and the friction characteristics within particles and the effect of moisture form on particle agglomeration.Taking the ash accumulated in the ash hopper of an electrostatic precipitator of a 600 MW thermal power plant as a sample,the fixed funnel method was used to measure the angle of repose,the halogen drying method was used to control moisture,and the outflow funnel method was used to characterize the fluidity.The influence laws were verified through multiple groups of parallel experiments.
