摘要
对某进口350MW亚临界W型火焰锅炉全烧烟煤改造后试验研究。通过试验研究掌握影响锅炉汽温参数主要因素。试验研究结果表明除了煤质对汽温参数有影响外,实际运行中降低一次风速、拱上风量、燃尽风率和增大乏气开度有利于维持汽温稳定,可为同类型锅炉设计运行提供参考。
An imported 350 MW subcritical W-shaped flame boiler was retrofitted by burning bituminous coal.Master the main factors affecting boiler steam temperature parameters through experimental research.The test results show that in addition to the influence of coal quality on steam temperature parameters,reducing primary air speed,air volume on the arch,burnout air rate and increasing exhaust gas opening are conducive to maintaining steam temperature stability in actual operation,which can provide reference for the design and operation of the same type of boiler.
