工(gong)業(ye)分(fen)(fen)析也(ye)叫(jiao)近似分(fen)(fen)析或(huo)實用分(fen)(fen)析，包括煤中水分(fen)(fen)、灰分(fen)(fen)和揮發分(fen)(fen)的測(ce)定及固定碳測(ce)算。煤的工(gong)業(ye)分(fen)(fen)析是(shi)了解煤質(zhi)特性的主要指標也(ye)是(shi)評價煤質(zhi)的基本依據，根據工(gong)業(ye) 各項(xiang)測(ce)定結(jie)果可(ke)初步判斷煤的性質(zhi)、種類和各種煤的加工(gong)利用效果及其工(gong)業(ye)用途。

全自動工業分析儀是一種(zhong)工業(ye)用儀器。用來測試水分、灰分、揮發分三種(zhong)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(he)在一(yi)起，在特定(ding)的(de)(de)(de)氣氛(fen)條件、規定(ding)的(de)(de)(de)時間內對受熱(re)過程中的(de)(de)(de)試(shi)樣予以(yi)稱(cheng)重(zhong)，以(yi)此計算出試(shi)樣的(de)(de)(de)水(shui)分(fen)(fen)(fen)(fen)、灰分(fen)(fen)(fen)(fen)及揮(hui)(hui)發(fa)分(fen)(fen)(fen)(fen)等工業分(fen)(fen)(fen)(fen)析指(zhi)標。實現(xian)水(shui)分(fen)(fen)(fen)(fen)、灰分(fen)(fen)(fen)(fen)、揮(hui)(hui)發(fa)分(fen)(fen)(fen)(fen)三(san)項指(zhi)標間任(ren)意組合(he)測(ce)定(ding)或單獨(du)測(ce)定(ding)，在150分(fen)(fen)(fen)(fen)鐘內可(ke)以(yi)測(ce)試(shi)19個(ge)樣品的(de)(de)(de)水(shui)分(fen)(fen)(fen)(fen)、灰分(fen)(fen)(fen)(fen)、揮(hui)(hui)發(fa)分(fen)(fen)(fen)(fen)三(san)項指(zhi)標。
