Abstract：Inordertoimprove theeficiencyoffluegasdesulfurizationincoal-fired powerplantsandenhance theutilization of by-product resources，this study analyzes the structural composition and operating parameters of existing wet flue gas desulfurizationsystems.Inresponse to the problems of largeeficiency fluctuations，high absorption liquid circulation leading toincreasedsystemoperating pressure，andunstableby-productqualitythat existinlong-termoperation，techical optimization paths such asspray tower flow fieldreconstruction，liquid gasratiooptimization，and slury discharge strategy adjustmentare proposed.Verifytheimprovementeffectof the proposedoptimizationschemeonkeyindicators suchas SO 2 removal rate，system pressre drop，and gypsum purity through case studies.The results indicate that dual optimization of structure and parameters can significantly enhance the operational stabilityof desulfurization systems，improvethevalueof by-product resource utilization，and provide support for desulfurization process optimizationand comprehensive esource utilization.
