大型火电机组湿法脱硫中石灰石制浆系统方案比选

石灰石制浆系统被广泛应用于燃煤电厂石灰石．石膏湿法烟气脱硫装置中。针对1000MW机组制浆系统的设计，对典型的湿磨制浆和石灰石粉制浆系统从工艺流程特点、设备组成、技术经济等方面进行分析比较。由于1000MW机组石灰石耗量较大，考虑电厂长期运行的经济性，推荐采用技术成熟、运行经济的石灰石湿磨制浆方案。同时要加强湿磨制浆系统在日常运行过程中的维护和管理。

Comparison and Selection of Limestone Slurry System Options in Wet Limestone-Gypsum FGD of the 1 000 MW Generating Unit

The limestone slurry system is widely used in limestone-gypsum FGD. With consideration to the design of the slurry system for the 1 000 MW generating unit,this paper compares and analyses the two typical techniques adopted-the wet type ball mill system and the limestone powder preparation system,in terms of process flow characteristics,equipment configuration and technical economics. With a view of the long-term economic operation of the 1 000 MW generating unit and considering its large limestone consumpti...
