摘要: 燃煤电厂脱硝改造工程技术难度大、工程成本高,考虑取消脱硝装置催化剂备用层。通过对催化剂“2+1”与“2+0” 2种管理运行方式的对比分析,发现取消催化剂备用层降低了工程技术难度和工程成本,但也导致了脱硝系统运行费用的增加。对脱硝装置有、无备用层的对比分析可为脱硝改造项目在规划、设计时提供指导和依据。

Abstract: The technical difficulty of deNOx system reformation project of coalfired power plant is larger, and its project cost is higher; so it was considered to cancel the standby catalyst layer in deNOx equipment. Based on comparative analysis of two management and operation modes of catalyst, which are ‘2+1’ and ‘2+0’, it was found that to cancel the standby catalyst layer can reduce project technical difficulties and the project cost, but it will increase the operation cost. The comparative analysis of deNOx equipments with and without standby catalyst layer can provide certain guidance and foundation for deNOx system reformation projects in planning and design stages.
