燃煤电厂脱硫脱硝除尘工艺评述

Review on the Desulfuration, Denitrification and Dedusting Processes in Coal-fired Power Plant

随着国家对环境问题的重视,对燃煤电厂排放污染物的标准也越来越严格。由于不同地区和不同规模燃煤电厂采取的生产工艺和污染物处理工艺不同,会导致燃煤电厂对环境产生的污染有较大差异。针对燃煤电厂处理污染物的脱硫、脱硝和除尘工艺,通过比较不同的处理工艺,列举出可去除污染物的普通工艺组合和标准工艺组合。经过对比分析,客观评述分析这两种工艺组合的优缺点,为燃煤电厂选用处理工艺提供参考或建议。

In recent decades, Chinese government had paid more and more attention to the environmental problems, and the standards of the discharge of pollutants have becoming stricter for the coal-fired power plants. The process and pollution treatment technique may be different in different coal-fired power plants in different region, so the pollution discharge situations also are different. In this work, we focus on the pollutants treatment process among the coal-fired power plants, including common process and standard process in those different treatment processes. After the comparison and analysis of the advantages and disadvantages, some important and valuable suggestions can be provide for proper coal-fired power plants.
