锅炉采用空气分级燃烧降低NO_(x)排放的同时也提高了主燃区h.(2)s.积分数。炉墙壁面过高的h.(2)s.积分数是加剧水冷壁高温腐蚀的重要因素。为保障新能源并网发电,大型燃煤机组灵活调峰的需求增加,不同负荷下的水冷壁近壁面h.(2)s.布特性值得关注。通过正交试验分析了切圆燃煤锅炉运行参数对水冷壁近壁面h.(2)s.积分数分布的影响。选取一台超临界600 MW切圆燃煤锅炉建立数值模型,设计L_(16)(4^(5))正交工况,覆盖100%BMCR、75%Th.,50%Th.以及35%BMCR四种负荷。建立了自定义s._(x)生成模型以确定燃料硫的析出和转化路径,模型包含多表面反应子模型以描述焦炭与O_(2)/CO_(2)/h.(2)O等3种气体的异相反应,并确定焦炭气化反应消耗量占总消耗量的比例,进而对炉膛h.(2)s.间分布进行了模拟计算。研究表明,近壁面高体积分数h.(2)s.域主要位于投运燃烧器层中最下层燃烧器以下以及最上层燃烧器以上至s.FA层之间,烟气切圆沿炉膛高度增加逐渐增大是造成后一区域h.(2)s.积分数较高的重要原因。35%BMCR负荷下水冷壁重点区域的h.(2)s.均体积分数为364μL/L,明显低于其他负荷。锅炉运行参数对重点区域h.(2)s.积分数影响程度的排序为:锅炉负荷>一次风率>主燃区空气过量系数>假想切圆直径>燃烧器竖直摆角。
