摘　　要：以某台600MW机组墙式燃烧锅炉为例,介绍了全新节油试验项目的方案设计、试验过程的重点监测项目、注意事项和节油试验的主要研究结果及实施后的效果。从中得出以下结论:(1)煤粉气流热着火计算模型和煤粉气流脱火、爆燃与炉膛负压变化模型是进行节油试验的重要依据和工具;(2)新开发的节油试验项目是墙式锅炉安全实施节油技术的必经途径与重要保证;(3)墙式锅炉日常磨煤机启停过程中的节油潜力巨大,节油率可达95%以上。Taking a 600 MW wall firing boiler for instant, several key problems in new oil-saving test were introduced, including the design scheme, main monitoring items, precautions, main results and effects. The test shows the following results： the models of coal flow igniting, blowing-off, bursting combustion and pressure fluctuating conlposites the essential basis and tools for oil-savlng test; the newly-developed oil-saving test is the inevitable way and guarantee for the implementation of oil-saving technology; the oil-saving potential during the startup and shutdown of pulverizer is great with the oil-saving rate above 95%.
