volatile matter content

Fragmentation by devolatilization may not happen if the volatile matter content is extremely small.

此外，挥发分含量极小的颗粒，可能不会发生脱挥发分破碎。

Effects of moisture, HGI, ash content and volatile matter in coal on pulverizing system performance and account of air are given by pulverizing system calculation.

制粉系统计算给出了燃煤水分、HGI、灰分及挥发分对制粉系统出力和通风量的影响。

Lignite, long flame coal, non-caking coal and weakly caking coal with higher ratio of atomic hydrogen to atomic carbon, higher volatile matter, lower inert component content and lower ash are suitable for direct liquefaction.

H/C原子比较高、挥发份较高、惰性组分含量和灰分较低的褐煤、长焰煤、不粘煤、弱粘煤等是适宜直接液化煤种。

The carbonization is carried out in autoclave under the pressure of volatile matter itself for low rank coals with high volatile matter content.

用低变质程度，高挥发分煤，于高压釜内在煤挥发分本身的压力下焦化。
