摘要
循环流化床是商业化运营最好的洁净煤发电技术,而CFB锅炉排烟污染物协同脱除是理论与实践亟需解决的又一技术难题。以唐山中浩化工有限公司240t/h锅炉为研究对象。通过对循环流化床锅炉烟气特性的分析,探讨了现有燃煤烟气各污染物之间的协同控制方法及脱除设备之间存在的相互作用;通过多级增湿半干法技术及添加复合性改性添加剂提高脱硫剂颗粒的含湿均匀性及吸收剂颗粒的比表面积,来延长吸收剂的反应时间,最大限度地实现燃煤烟气中各污染物的高效协同脱除。文中研究结果可为CFB电站的优化设计和运行提供理论和技术支撑。
The commercial operation of the circulating fluidized bed is the best clean coal power generation technology and CFB boiler flue gas pollutants removal is a technical problem in theory and practice to solve. The 240 t / h Boiler in Tangshan Hao Chemical Co. Ltd. as the research object by analysis of circulating fluidized bed boiler flue gas characteristics,to explore the synergistic interaction between control method and apparatus for removing existing coal-fired flue gas between each pollutant; through multi-stage humidification semi dry technique and adding composite modified additive to increase the desulfurizer particles with uniform wetting and absorbent particles and the specific surface area and to extend the absorber reaction time,maximum achieve collaborative and efficient removal of pollutants in the flue gas. To provide theoretical and technical support to optimize the design and operation of the research results can be used for CFB power plant.
