粉煤灰中微珠的初步研究

Preliminary Study of Microbeads in Coal Ash

火电厂排放出的粉煤灰,通常作为制砖材料,但若作精加工,可大大提高其经济价值。其中微珠耐高温,可作高温保温充填粉;碳灰含碳量达70％以上,可加工成碳素产品。

Coal ash rejected from the thermal power plant is usually used as raw mo(?)erial for making bricks, but its economic value may be raised to a higher level if it is refined. Microbeads can be used as filling powder of thermal insulition and high temperature resistance and the carbonaceous products can be also made from it if carbon content in the ash reaches more than 70%.
