工(gong)業(ye)分(fen)(fen)析也叫近似分(fen)(fen)析或實(shi)用(yong)分(fen)(fen)析，包括(kuo)煤(mei)(mei)中(zhong)水(shui)分(fen)(fen)、灰分(fen)(fen)和(he)揮發(fa)分(fen)(fen)的(de)(de)測定(ding)及(ji)固(gu)定(ding)碳測算。煤(mei)(mei)的(de)(de)工(gong)業(ye)分(fen)(fen)析是了解煤(mei)(mei)質(zhi)特性(xing)的(de)(de)主(zhu)要指標也是評價煤(mei)(mei)質(zhi)的(de)(de)基本依(yi)據，根據工(gong)業(ye) 各(ge)項測定(ding)結(jie)果可初步判斷煤(mei)(mei)的(de)(de)性(xing)質(zhi)、種類和(he)各(ge)種煤(mei)(mei)的(de)(de)加工(gong)利(li)用(yong)效果及(ji)其(qi)工(gong)業(ye)用(yong)途。

全自動工業分析儀是一種工業用儀(yi)器(qi)。用來測(ce)試(shi)水分、灰分、揮(hui)發分三種指標。

由分析儀、計算機系統、打印機三部分組成。其將遠紅外加熱設備與電子天平結合在一起，在特定(ding)(ding)的(de)(de)氣氛條(tiao)件、規定(ding)(ding)的(de)(de)時間(jian)內對受熱過程中的(de)(de)試樣(yang)予以(yi)稱重，以(yi)此計算(suan)出試樣(yang)的(de)(de)水(shui)分(fen)(fen)、灰(hui)分(fen)(fen)及揮(hui)發分(fen)(fen)等工業(ye)分(fen)(fen)析(xi)指標。實現水(shui)分(fen)(fen)、灰(hui)分(fen)(fen)、揮(hui)發分(fen)(fen)三(san)項指標間(jian)任意組合測(ce)(ce)定(ding)(ding)或單獨測(ce)(ce)定(ding)(ding)，在150分(fen)(fen)鐘內可以(yi)測(ce)(ce)試19個樣(yang)品的(de)(de)水(shui)分(fen)(fen)、灰(hui)分(fen)(fen)、揮(hui)發分(fen)(fen)三(san)項指標。
