对某厂使用的径向浓淡旋流燃烧器中心扩锥和浓缩器的材质及磨损失效方式进行了研究 ,在此基础上进行了高温耐热抗磨材料的生产工艺和性能比较试验。试验结果表明 ,研制的新型材料在性能上超过了燃烧器现用材料并且运行良好 ,有一定应用前景。 Based on the research on the material and wear failure mode of the center expansion cone and concentrator of a radial shading swirl burner used in a factory, the production process and performance comparison test of the high temperature heat-resistant and wear-resistant material are carried out. The test results show that the new material developed has better performance than the current material of the burner and works well with certain application prospects.
