摘要

煤中含有多种有害元素,这些元素会在燃烧或热解条件下迁移转化到水体、大气及产品当中,不仅对设备装置造成腐蚀,还对自然生态和人体健康造成威胁或侵害。近年来,随着国家以及社会对环保的重视,污染物排放标准日趋严苛。因此,研究煤中有害元素赋存形态,高温条件下矿物组成与有害元素的耦合作用机理,有害元素的迁移转化和控制对煤炭行业发展有着十分重要的意义。

关键词: 煤;有害元素;迁移转化;控制

Abstract

Coal contains various harmful elements, which can migrate and transform into water, atmosphere, and products under combustion or pyrolysis conditions. This not only causes corrosion to equipment and devices, but also poses a threat or infringement to natural ecology and human health. In recent years, with the increasing attention of the country and society to environmental protection, pollutant discharge standards have become increasingly stringent. Therefore, studying the occurrence forms of harmful elements in coal, the coupling mechanism between mineral composition and harmful elements under high temperature conditions, and the migration, transformation, and control of harmful elements are of great significance for the development of the coal industry.

Key words: Coal; Harmful elements; Migration conversion; Control
