摘要

燃煤锅炉受热面大都存在积灰和结渣现象，使用高灰分和高硫分煤的锅炉积灰问题更为严重。基于对现有清灰器的优缺点分析，本文推出一种新型蒸汽脉冲式声频清灰器。对该清灰器三维流道建模，结合声波清灰原理详细分析清灰过程中流体总压降随开度变化关系以及流场中压力和速度的变化趋势；对比某电厂安装该清灰器运行前后的部分关键数据，计算该清灰器带来的经济效益与环保效益。结果表明：清灰器开度变化时，流体域每一点均会产生压力和速度脉动，将流体的机械能转化为脉冲波振荡，从而实现清灰目的；该清灰器投运某锅炉后，排烟温度平均降低16.35 ℃，且未发生低温腐蚀，年节煤量与节汽量分别为1 650 t和21 192 t，CO2与SO2的年减排量为726 t和33 t，此外，每年还可减少约25 t烟尘和429 t灰渣排放，年发电耗煤节约160万元以上，年获益98万元。
