摘要

选择性非催化还原法（SNCR）脱硝系统中，还原剂内混式喷枪的流量特性和雾化特性对脱硝效率影响较大。本文通过实验研究了影响雾化特性的主要因素气、液压力和气液比对内混式SNCR喷枪流量特性和雾化特性的影响，尤其是对喷枪射程的影响。结果表明：喷枪内液体流量实验曲线基本符合Qw≈(pw－p3)0.5的指数增长关系；喷枪最佳设计气体压力为pw≤pa≤pw+0.1 MPa；随着液体压力的增大，雾化颗粒变大，射程增幅明显；随着气液比的增加，雾化颗粒越来越细，射程逐渐变小，考虑刚度射程问题时，气液比选择在0.10左右较为合宜，且设计气液比kALR≤0.10时可以明显的增加射程；增加气、液的初始压力不能显著改善喷枪穿透深度。
