摘要

利用热天平研究了7种不同工业废弃物(工业废渣)对云贵无烟煤和福建无烟煤着火温度的影响

发现盐泥2、锌渣、首钢和莱钢转炉渣对无烟煤着火温度的降低有着良好的催化作用

且催化作用随着工业废渣添加比例的增加而增强。通过对废渣成分的XRD分析

发现这些工业废渣中不同程度地含有碱金属、碱土金属的氧化物及其盐类。将几种工业废渣按一定比例混合后加入无烟煤燃烧

结果表明其催化效果明显强于1种工业废渣的催化效果。

Abstract

By using the thermogravimetric analyser

the influence of seven different industrial wastes slags upon the ignition temperature of Yungui anthrathetic coal and Fujian anthrathetic coal has been studied

the results show that the second white lime mud

zincilate

steelmaking slag from shougang and LWG have a better effect upon reducing the ignition tempertaure of anthrathetic coal.By enhancing the adding proportion of waste slag

the ignition temperature can further be decreased.Through XRD analysis

it is discovered the composition of waste slag was consisted in different degree of alkaline metals

oxides of alkaline-earth metals

and their salts

several industrial waste slags were mixed according to certain proportioning ratio and being added into anthrathetic coal to burn

the catalytic effect of them was substantially stronger than that of a single waste slag.
