摘　　要：一家以废酸裂解制硫酸的工厂希望通过处理更多废酸来提高硫酸产量,要求采用对设备和操作修改最少的改造方案。梅塞尔公司的解决方案是采用两步引入氧气的方式,一是将部分氧气与燃烧空气混合提高氧气浓度,二是将部分纯氧直接注入炉内。改造实现了提高废酸裂解的处理量和增加硫酸产量的目标,同时没有增加NO_(x)排放量。对系统的启动和运行调整进行了总结,并介绍了开车和运行调整过程中的改进和经验教训。A plant operating a spent acid decomposition furnace as part of its sulphuric acid production facility desired to increase acid production primarily by processing additional spent acid while making minimal modifications to the plant equipment and operations.The Messer solution entailed introducing oxygen in two steps,both as an enrichment to the combustion air and by direct injection into the furnace.The resulting performance improvements exceeded the project objectives for acid production and spent acid decomposition,without increasing NO_(x) emissions.This paper provides a summary of the system start-up and tuning and presents the resulting improvements and lessons learned.
