Study on dust reduction at source technology based on coal particle movement control
Beijing Huayu Engineering Co., Ltd, Beijing , China
Dust control during the transfer process in coal preparation plants presents a significant challenge. To address this problem, a model was developed to analyze dust detachment and adhesion as well as a kinematic model for the coal transfer process. A source-based dust reduction technology was proposed as a solution with specific focus on coal particle flow control. DEM (Discrete Element Method) analysis software was used to conduct a comparative analysis of the coal particle flow dynamics in both conventional and curved coal falling chute systems. A test rig was developed to study dust generation and collection during coal transfer. Experimental and analytical results showed that the curved coal chute design reduced dust generation by 40.96% weight compared to conventional chutes, offering valuable insights for optimizing dust control in coal transfer operations.
