中储式制粉系统粗粉分离器选型原则的探讨

PRINCIPLES FOR CLASSIFIER SELECTION FOR COAL PULVERISING SYSTEMS WITH TUBE MILLS

粗粉分离器的选型对其运行性能有很大影响。文中尝试性地将分离器的选型分为型式的选择和参数的选择,根据半工业性模型对比试验结果,提出了型式选择原则;通过对各电厂制粉系统工业性试验结果的统计分析,得到了较为合理的参数选择原则,以期为粗粉分离器的选型提供依据。

To select tbe classifier for a coal pulverising system with tube mills is very important to its operation. The Selection ofclassifier, is divided in this paper into type selection and parameter selection. Principles for type selection is proposed on thebasis of contratesting results of Pilot-scale while principles for the parameter selection on the basis of staistical analysis ofthe testing results of fuI1-Scale. These principles have provided a good basis for the classifier selection.
