配煤对成浆性的影响

安徽理工大学毕业论文I配煤对淮南煤成浆性能的影响摘要淮南煤煤质优良，可以制出浓度70%左右的水煤浆，但淮南煤灰熔融温度过高，不适合淮化集团近年引入的德士古水煤浆气化炉的液态排渣工艺温度要求。针对水煤浆加压气化过程中的高灰熔融温度煤种，进行了配煤实验研究，结果表明，通过配煤可有效降低煤样灰熔融温度，同时其成浆性能得到改善，对实现水煤浆加压气化原料多样化及煤炭资源的合理利用具有重要的现实意义。不同变质程度的煤混配，可相应改善煤种的成浆性能，提高制浆浓度，而煤样的反应活性并不会受大的影响，利用淮南煤与蒙煤和华亭煤配煤制浆可以有效提高蒙煤和华亭煤的制浆浓度，一般在同等粘度下可以提高3%～8%，但不同煤种配煤制浆结果有一定的差异。关键词：德士古，配煤，灰熔融温度，水煤浆，成浆性安徽理工大学毕业论文IIEFFECTOFCOALBLENDINGONTHESLURRINGPROPERTIESOFHUAINANCOALSABSTRACTHuainancoalfinecanbeproducedabout70%oftheconcentrationofcoal-waterslurry,buttheHuainancoalashfusiontemperatureistoohigh,notsuitableforHuaihuaGroupintroducedinrecentyears,TexacoGasifierSlag-tapcoal-waterslurryprocesstemperaturerequirements.Fortheprocessofcoal-waterslurrypressurizedgasificationmeltingtemperatureofthehigh-ashcoal,acoalblendingexperimentalresearchresultsshowthatcoalcanreducethemeltingtemperatureofcoalasthatthesametimeitsperformancehasimprovedslurryabilityforachievingwatercoalslurrypressurizedgasificationrawmaterialdiversityandtherationalutilizationofcoalresourceshasimportantpracticalsignificance.Differentmixturesofcoalrank,correspondingtothecoalslurrytoimproveperformance,increasethepulpconcentration,andreactivityofcoalandwillnotbeaffectedbyalargeimpactontheuseofHuainancoalandcoal-MongoliancoalandcoalpulpHuatingcaneffectivelyimprovetheMongolianHuatingcoalandcoalpulpconcentration,generallyinthesameviscositycanbeincreasedby3%to8%,buttheresultsofpulpblendingdifferentcoalshavesomedifferences.KEYWORDS:Texacogasification，coalblending，ashmeltingpoint，coal-waterslurry安徽理工大学毕业论文目录摘要.............................................................................................................................................IABSTRACT..............................................................................................................................II绪论............................................................................................................................................11文献综述.................................................................................................................................21.1我国的能源概况..............................................................................................................21.2TEXACO水煤浆气化工艺.................................................................................................21.2.1水煤浆气化技术.......................................................................................................21.2.2Texaco气化工艺简介...............................................................................................21.2.3Texaco水煤浆气化的技术特点...............................................................................41.2.4Texaco水煤浆气化技术的应用...............................................................................51.2.5Texaco气化对煤质的要求.......................................................................................51.2.6Texaco对水煤浆性能的基本要求...........................................................................51.3影响水煤浆流变特性的因素..........................................................................................61.4配煤对煤的灰熔融性和成浆性能的影响......................................................................81.5水煤浆的应用及研究现状..............................................................................................91.5.1水煤浆的应用概述...................................................................................................91.5.2水煤浆添加剂的研究现状.......................................................................................91.6研究内容........................................................................................................................102实验部分...............................................................................................................................112.1实验原料........................................................................................................................112.2实验方法........................................................................................................................122.2.1灰熔融温度测定.....................................................................................................122.2.2水煤浆成浆性能的测定.........................................................................................123实验结果与讨论...................................................................................................................153.1淮南煤配蒙煤对煤灰熔融温度的影响........................................................................153.2单煤水煤浆性能的测定................................................................................................183.3淮南煤配蒙煤水煤浆性能的测定................................................................................203.4淮南煤配华亭煤对煤灰熔融温度的影响....................................................................263.5淮南煤配华亭煤水煤浆性能的测定............................................................................273.6配煤效果比较................................................................................................................323.6.1配煤对灰熔融温度的影响......................................
