| 摘 要： | 燃煤电厂是汞的最大的排放源。燃煤电厂的汞主要存在于烟气中,且呈现为微粒结合汞、氧化汞和单质汞3种形态。为了满足汞捕捉的环保要求,美国能源部等单位多年来针对利用常规的脱硫、脱硝、除尘等空气污染控制设施和技术,进行一体化汞脱除的研发工作。研究结果表明,利用燃煤电厂常规的除尘、脱硫、脱硝等空气污染控制设施,就能在一定程度上达到一体化脱汞的目的。一体化脱汞技术为燃煤电厂的发展提供了又一种清洁燃烧技术,介绍了美国一体化脱汞技术的开发情况。

| Abstract: | Coal-fired power plants are the largest source of man-made mercury emissions.Mercury from coal-fired power plants mainly exists in flue gas in three general forms:particulate-bound mercury,oxidized mercury and elemental mercury.To meet the environmental requirements of mercury capture control,for the conventional air pollution control devices and technologies such as FGD,SCR and dust removal,the integrated mercury removal technologies were researched by U.S.Department of Energy and other organizations since... |
