1、华jB电力大学硕士学位论文摘要摘要本文对燃煤电厂中湿式石灰石一石膏法脱硫系统的原理及其工艺,结合己运行系统进行了探讨,对影响脱硫效率的各种因素,如:烟气S02浓度,液气比,PH值,停留时间,吸收反应过程,吸收反应特性,最终产品石膏的形成进行了理论分析和研究。通过对装置的设备,系统特性的研究,针对不同工况对关键参数进行优化,从而使FGD达到最佳运行状态,减少运行成本,使之更适于推广应用。关键词:脱硫,效率,优化,仿真Abstra,ctn圮paperdiscussedtheprinciplesandprocessatthewetlimestone-gypsumdesulphurization
