【摘要】 介绍160t／h微正压燃油锅炉炉内及旋流燃烧器出口空气动力场测试方法和测试结果，讨论加模拟火炬气前后空气动力场的变化。测试结果与分析认为，旋流燃烧器出口前具有显著的回流区和涡流区，对燃烧火焰的稳定和锅炉稳定运行有重要作用；但加模拟火炬气后，旋流燃烧器出口前的空气动力场发生了比较明显的改变，对燃烧火焰稳定有较明显的影响。更多还原

【Abstract】 Air dynamics field test method and test results in 160t/h positive pressure oil-fired boiler and vortex burner outlet are introduced and changes of air dynamics field with and without the simulated torch gas are discussed in this paper. Test results and analysis showed that apparent reversed flow and vortex flow areas occurred ahead of voffex burnr outlet, which was important for stable flame and operation of boiler. Apparent changes took place in air dynamic field at vortex burner outlet which would affect the stability of burning and boiler operation.更多还原
