摘要
CFB锅炉具有环保特性优越、燃料适应性好的特点,但其环保特性的发挥也受多方面因素的影响。本文结合国家最新的环保标准,对影响CFB锅炉炉内脱硫和脱硝的因素进行了分析,通过对相关参数进行优化控制和必要的技术改造,在避免高昂设备投资和运行维护投入的前提下,完全可以将CFB锅炉的环保特性充分发挥,满足国家最新环保标准的要求。
Compared with the PC boiler,CFB boiler has many advantages.For example,it has high desulfurization efficiency when limestone powder is simply injected into the furnace;it has low NOx emission because of low combustion temperature,wide fuel adaptability and excellent load adjustment ability.This paper analyzes factors of effect desulfurization and denitration under current environmental standards.Operation optimize and facility retrofit could improve environmental protection characteristics of CFB boiler.The circulating fluidized bed boiler technology will has broad application avoid overmuch investment.
