clarain

基本解释

The particle size of clarain declines more rapidly than that of culm.
燃燒後期, 亮煤的顆粒破碎比灰煤更快；
The fragmentation of clarain and culm tends to be severely with the increase of particle size, bed temperature and combustion time.
而暗煤顆粒則因相反的原因不發生破碎或僅發生輕微破碎。
Clarain from Tongting (Huaibei, Anhui Province, China) bituminous coal was extracted with CS2 using fractional extraction, and then the extracts were analyzed with GC/MS.
摘要以CS2爲溶劑對童亭亮煤進行了按時間段分次取樣的索氏溶劑萃取，採用GC/MS對各次萃取物進行了定性分析。
For clarain, which has a relatively lower density, an extremely low volatile, and a higher fixed carbon content (> 80%), the primary maceral is vitrinite.
暗煤富含鑛物質成分，密度極高但含碳量卻很少，熱值很低，接近於原煤中的矸石。
The combustion model of clarain in fluidized bed is equidensity shrinking core model, while that of durain is equidiameter one, and that of culm is a mixed model.
亮煤在流化牀燃燒中服從等密度燃燒模式, 暗煤服從等直逕燃燒模式, 而灰煤則服從混郃燃燒模式。
