clarain
常見例句
- 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(fā)生破碎或僅發(fā)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(wèi)溶劑對(duì)童亭亮煤進(jìn)行了按時(shí)間段分次取樣的索氏溶劑萃取,採(cǎi)用GC/MS對(duì)各次萃取物進(jìn)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(zhì)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。 - In the early stage of combustion, the mean particle size of clarain decreases promptly as a result of primary fragmentation, but with the time going it falls to a stable size.
由於破碎, 入爐煤顆粒平均粒逕在燃燒早期迅速減小, 而後隨著燃燒的進(jìn)行而逐步趨於一個(gè)穩(wěn)定值; 返回 clarain
