燃煤污染治理综述
首发时间:2006-04-17
摘要:我国是煤炭生产和消费大国,煤主要用作动力燃料和发电。煤中的碳、氢、氧、氮、硫等元素,在燃烧过程中生成的SO2、NOx、CO2并产生大量粉尘,这些污染物尤其是SO2污染给自然环境和人体健康带来了很大的危害。燃前脱硫、燃中固硫、燃后净化、建立大型干法选煤坑口电站、发展煤炭转化技术及寻找无污染替代燃料等措施对提高煤炭利用率,降低污染物排放,改善环境状况有重要意义。

An Overview of Coal Burning Pollution and Treatment Technologies
Abstract:China is the biggest country of coal production and consumption and the coal mainly is used as power fuel and to generate electricity. During the burning the elements in coal, for example carbon, hydrogen, oxygen, nitrogen and sulfur, will change into SO2, NOx and CO2, also mass dust. These contaminants have seriously harmed to natural environment and the health of human beings. Desulfuration before coal burning, sulfur fixation during coal burning, decontamination after coal burning, the building of big pit power station by the pneumatic dry, development of coal conversion and steady of none contaminants fuel all can increase the use ratio of coal and decrease the amount of contaminants letting out. The study of these new technologies has great significance.
