An experiment was conducted to study the effects of flue gas components on the mercury adsorption by coal-fired fly ash by using a bench-scale fixed bed.

在小型固定床试验台上开展了烟气成分对燃煤飞灰汞吸附影响的试验研究。

Secondly, grinding effect of every monomer grinding aids with fixed content on fly ash cement and slag cement is tested. The effect on the properties of fly ash cement and slag cement is also tested.

其次，本文研究了几种单体助磨剂固定掺量对粉煤灰水泥和矿渣水泥的助磨效果和对水泥性能的影响。

Generally speaking, the coal of power plant is low-grade, high-ash (the low content of fixed carbon) and the effect of direct gasification is bad.

一般说来，电站煤质的品位低、灰含量高(低的固定碳含量)，直接气化效果很差。
