摘 要:目前我國干煤粉熔渣氣化裝置較多,其生產(chǎn)過程受煤中灰分穩(wěn)定性的影響較大。分析了煤灰的組分、性質(zhì)以及灰熔性特征溫度對(duì)氣化效果的影響;采用Ashizawa等和戴愛軍等回歸的經(jīng)驗(yàn)公式或多元相圖對(duì)煤的灰熔點(diǎn)進(jìn)行了較為準(zhǔn)確的預(yù)測(cè);研究了煤灰分的黏結(jié)性、微量組成、黏溫曲線和臨界溫度等對(duì)煤氣化裝置運(yùn)行操作的影響。
關(guān)鍵詞:熔渣氣化;灰成分;灰熔點(diǎn);黏溫曲線;臨界溫度;影響因素

Abstract:Nowadays There are relatively many dry pulverized coal gasification plants with melting slag in China,of which the productive process was effected more by stability of ash composition in coal.Author has analyzed the influence of coal ash composition,its property and characteristic temperature of coal ash melting on gasification efecet;has relatively accurately predicted the melting point of coal ash using the regressive and empirical e....
