摘　　要：介绍了国电福泉电厂烟气脱硫工程制酸装置的工艺流程及运行情况。回顾了工艺技术方案比较与选择,工艺优化设计。对开车过程中出现的问题与采取的措施进行了总结。该制酸装置采用高浓度SO2制酸、预转化、带低温位热能回收的一转一吸工艺,硫酸产量为1 050 t/d,SO2转化率为96.5%。Process and operating conditions of flue gas desulphurization-acid plant in Guodian Fuquan power plant are described. Comparison and selection of process technology scheme and design optimization are reviewed. Problems happening in driving and measures are summarized. The device uses a single process with low level heat energy recovery, producing sulphuric acid acid by high con- centration of SO2 and then pre-conversion. The production of sulphuric acid is 1 050 t/d and conversion rate of SO2 is 96. 5%.
