循环流化床锅炉半干法脱硫装置运行问题分析及改造

PROBLEM ANALYSIS AND REFORMATION OF SEMI-DRY DESULFURIZATION PLANT OF CFB BOILER OPERATION

介绍循环流化床锅炉半干法脱硫装置运行情况,分析运行期间遇到的故障和原因,优化脱硫运行工况,进行技术改造,节约运行成本,实现循环流化床锅炉烟气SO2浓度稳定、长周期超低排放。

The operation of CFB boiler semi-dry desulfurization plant was introduced. The faults and their reasons during operation was analyzed. By optimizing the work case of desulfurization, technical reformation and cost saving measures, the content of SO2 in the flue gas of CFB boiler was kept in a stable and lower level emission.
