结合目前国内外先进的烟气脱硫技术特点，对热电厂（2×350 MW+2×50 MW）机组的海水脱硫方案，从保障电厂安全可靠运行、优化电厂脱硫及全厂总体布置、节省项目投资及降低运行费用等方面进行了技术经济比较和优化建议，推荐了适合本类工程的海水脱硫系统最佳方案。

Combined with the advanced flue gas desulfurization(FGD) technology at home and abroad at present, the technical and economic comparisons and optimization proposals are implemented of seawater desulfurization plan for two 350 MW and two 50 MW units in the thermal power plant, including ensuring the safe and reliable operation of the plants, optimizing SWFGD(seawater FGD) system and general layout, saving the project investments and lowering operating costs, The preferred plan of SWFGD system for this kind of project is recommended.
