海水脱硫在300MW混烧高炉煤气发电机组中的应用

Sea-Water Desulfurization Practice on 300 MW Power Plant Using BFG as Auxiliary Fuel

介绍首钢京唐公司海水脱硫工艺原理及技术特点，以300Mw（混烧30％高炉煤气）发电供热汽轮机组为例，分析了海水脱硫经济性，单位脱硫成本为0．66分／（kW·h）；评估了对海洋环境的影响，通过1年的水质监测，排水水质达到GB3097-1997《海水水质标准》二级标准。

Technical principle and characteristic of sea-water desulfurization are introduced by taking 300 MW power plant which can burn 30% BFG （max） as auxiliary fuel for example. Economic cost of sea-water desulfurization is also considered, that is 1. lfen/（kW.h）. The influence of marine environment is addressed by one-year water quality monitoring. The wastewater quality reached the standard of grade Ⅱ of national marine water quality.
