摘要

为研究烟道凝聚器的凝聚机制及颗粒物减排特性，通过商业计算流体力学（computational fluid dynamics，CFD）软件，模拟并得到了凝聚器湍流区定常/非定常工况条件下的流场特性；理论计算了凝聚器内颗粒的凝聚过程，并通过扫描电镜进行了验证；实验室中凝聚器对PM2.5的减排幅度为20.8%，实际工程中，300 MW和660 MW机组PM2.5的减排幅度分别为30.1%和37%。研究结果可为颗粒凝聚技术的大规模工程应用提供参考。

Abstract

In order to study the aggregation mechanism and particulate emission reduction characteristics of the flue agglomerator

the flow field characteristics of the turbulent region of the agglomerator under steady/unsteady conditions were simulated and obtained by commercial computational fluid dynamics (CFD) software.The agglomeration process of particles in the agglomerator was theoretically calculated and verified by scanning electron microscope (SEM). The agglomerator in the laboratory reduced PM2.5 emissions by 20.8%

compared with 30.1% and 37% in the actual project. The results can provide reference for large-scale engineering application of particle coagulation technology.
