A critical review on lead migration, transformation and emission control in Chinese coal‐fired power plants

Coal is widely utilized as an important energy source, but coal-fired power plant was considered to be an important anthropogenic lead emission source. In the present study, the distribution characteristics of lead in coal and combustion by-products are reviewed. Specifically, lead is mainly transferred to ash particles and the formation and migration mechanisms of particulate lead are summarized. Also, targeted measures are proposed to control the formation of fine particulate lead as well as to increase the removal efficiency during the low-temperature flue gas clean process. In detail, interactions between gaseous lead and some coal-bearing minerals or added adsorbents could obviously suppress the formation of fine particulate lead. On the other hand, some efforts (including promoting capture of fine particles, reducing resistivity of particles and strengthening the gas-liquid contact) could be made to improve the fine particulate lead removal capacity. Notably, the formation mechanism of fine particulate lead is still unclear due to the limitations of research methods. Some differences in the removal principles of fine particles and particulate lead make the lead emission precisely control a great challenge. Finally, the environmental potential risk of lead emission from flue gas and ash residues is addressed and further discussed.

富含黄铁矿的煤矸石中碳酸盐影响其风化淋溶性质的研究

富含黄铁矿的煤矸石在风化淋溶过程中，碳酸盐含量不仅控制其风化程度，而且控制淋溶液的酸度。风化淋溶实验结果表明，Ｆｅ的淋溶量主要受控于酸度，而Ｍｎ＾２＋与ＳＯ４＾２－的淋溶量主要取决于其风化程度。

固硫煤和普通煤对SO2污染和健康危害的对比研究

探讨固硫煤与普通煤燃烧造成室内SO2污染及对健康的危害作用.将家兔分别喂养在燃烧固硫煤、普通煤和不烧煤的环境中连续观察90d,每天监测室内环境中SO2、CO的浓度;实验各时期测定家兔LYS含量和血清中SOD、GSH-PX、SA浓度.结果:固硫煤组SO224h平均浓度(2.68mg/m3)明显低于普通煤组(13.04mg/m3),但CO水平两组间无明显差异.实验90d后与实验前的GSH-PX值的差值比较,普通煤＞空白对照组＞固硫煤组,普通煤和固硫煤组间的差别有显著性意义(p＜0.05);SOD、SA、LYS值在实验期有所变化,但各组间的差别无显著性意义 (p＞0.05).结论:提示燃煤煤烟中SO2能影响生物体内SOD、GSH-PX、LYS、SA的浓度变化,燃烧固硫煤能明显降低SO2的污染,故使用固硫煤可减少燃煤煤烟对健康的危害.     

浅议包头市大气环境中苯并(a)芘的污染

苯并(a)芘(Bap)是强致癌物之一，主要来源为煤、石油等矿物性燃料及其他有机物的不完全燃烧。本文通过对包头市1991～2000年大气苯并芘监测结果的统计分析，揭示了其污染状况及变化趋势，从而说明包头市大气环境中Bap主要来源于燃煤。
