描述

從礦井中直接開采出來(lái)的煤炭叫原煤，原煤在開采過(guò)程中混入了許多雜質(zhì)，而且煤炭的品質(zhì)不同，內(nèi)在灰份小和內(nèi)在灰份大的煤混雜在一起。洗煤就是將原煤中的雜質(zhì)剔除，或?qū)?yōu)質(zhì)煤和劣質(zhì)煤炭進(jìn)行分門別類的一種工業(yè)手藝。洗煤是煤炭深加工的一個(gè)不可缺少的工序，.洗煤過(guò)程后所產(chǎn)生的產(chǎn)品一般分為有矸石、中煤、乙級(jí)精煤、甲級(jí)精煤，經(jīng)過(guò)洗煤過(guò)程后的成品煤通常叫精煤，通過(guò)洗煤，可以降低煤炭運(yùn)輸成本，提高煤炭的利用率，精煤是一般可做燃料用的能源，精煤一般主要用于煉焦，它要去硫，去雜質(zhì)等工業(yè)過(guò)程，以達(dá)到煉焦用的標(biāo)準(zhǔn)。為了去除煤炭中矸石，以防在高溫燃燒中溶結(jié)為一體結(jié)塊，容易堵塞爐膛或其它燃燒設(shè)施，而且它不燃燒減少燃燒熱量影響效率。
