摘要
随着全球环保法规的持续收紧,燃煤机组实现超低排放已成为电力行业的核心挑战。半干法循环流化床超低排放技术基于气固流态化原理,通过多污染物协同控制机制,在脱硫、脱硝及除尘方面展现出显著优势。该文系统阐述该技术的反应机理、关键工艺参数及其在超低排放中的应用效能,结合某300 MW机组改造案例验证其污染物排放浓度(SO_(2)小于30 mg/m^(3)、NO_(x)小于40 mg/m^(3)、颗粒物小于8 mg/m^(3))的达标能力。通过分析技术瓶颈与设备耐久性问题,提出智能化控制与多技术耦合的发展路径,为电力行业绿色转型提供实践参考。
As global environmental regulations continue to tighten,achieving ultra-low emissions from coal-fired units has become a core challenge for the power industry.Semi-dry circulating fluidized bed ultra-low emission technology is based on the principle of gas-solid fluidization and shows significant advantages in desulfurization,denitrification and dust removal through a multi-pollutant collaborative control mechanism.The paper systematically describes the reaction mechanism,key process parameters and its application efficiency in ultra-low emissions of the technology.Combined with the transformation case of a 300 MW unit,it verifies its ability to meet the standards of pollutant emission concentrations(SO_(2)<30 mg/m^(3),NO_(x)<40 mg/m^(3),particulate matter<8 mg/m^(3)).By analyzing technical bottlenecks and equipment durability issues,the development path of intelligent control and multi-technology coupling is proposed to provide practical reference for the green transformation of the power industry.
