摘要
随着国家环保要求的日益严格,为解决机组负荷较低时,SCR脱硝系统因脱硝入口烟气温度低于催化剂最低喷氨温度而无法投运的问题,进行了对几种技术改造方案的阐述和各方案优缺点的对比分析,为同类型机组提供了技术改造参考依据。
National environmental protection requirements are increasingly stringent. When unit load is lower, SCR-DeNOx system cannot be put into operation due to denitration catalyst inlet flue gas temperature is lower than the minimum spray ammonia temperature. This paper described several transformation programs, compared the advantages and disadvantages of each option to provide a technical renovation reference for the same type of unit.
