本文介绍了轴流式分离器的工作特性和冷态试验方法,对试验结果作了一些初步探讨和分析。本试验主要作了叶片型式、阻挡器及阻尼环等方面的结构选型,并对分离器性能的改进作了初步尝试。通过冷态试验推荐了分离效果较好、阻力较小和结构较简单的轴流式分离器的结构型式。(原文见东方锅炉厂技术报告) This paper introduces the working characteristics of the axial flow separator and the cold test method, and makes some preliminary discussions and analyzes on the test results. This test mainly made the blade type, blockers and damping ring and other aspects of the structure selection, and the separator performance improvements made a preliminary attempt. The structure type of axial-flow separator with better separation effect, smaller resistance and simpler structure is recommended by cold test. (See the original Eastern Boiler Technical Report)
