1) ash content in coal
煤炭灰分
1.
The structure,principle,calibration method,and affecting factors in detection of a portable analyser for ash content in coal based on low-energy γ-ray method have been presented.
该法在煤炭灰分的测量精度方面虽不及试验室的常规测定,但测量周期很短,仅为30s,加之该仪器重量轻,可任意移动,将有较好的应用前景。
2) coal fly ash carbon
粉煤灰炭
1.
Activated carbon made from coal fly ash carbon in a power plant;
电厂粉煤灰炭制造活性炭的研究
3) ash removal from raw coal
煤炭脱灰
4) separated carbon fly ash
脱炭粉煤灰
1.
Using “double mixed” technology of separated carbon fly ash and decreasing aqua of highly effect and early strong, the renovation technologies of highway concrete pavement were studied.
研究了粉煤灰的资源化特性，提出了粉煤灰脱炭高值利用理论；利用脱炭粉煤灰和高效早强减水剂的“双掺”技术，进行了公路混凝土路面的修复技术研究；结果表明脱炭粉煤灰用于混凝土路面替代水泥量可达 ２０％ ，较好地解决了公路路面工程中直接利用粉煤灰所存在的主要问题。
6) grading of coal
