Hordhac ku saabsan Dhuxusha
Dhuxushu waa nooc ka mid ah macdanta fosil ee kaarboonaysan. Waxaa abaabula kaarboon, haydarojiin, oksijiin, naytaroojiin iyo walxo kale, kuwaas oo inta badan dadku u isticmaalaan shidaal ahaan. Waqtigan xaadirka ah, dhuxushu waxay leedahay 63 jeer mugga kaydka ee la sahamiyay marka loo eego batroolka. Dhuxushu waxaa loogu yeeri jiray dahabka madow iyo cuntada warshadaha, waana tamarta ugu weyn tan iyo qarnigii 18aad. Intii lagu jiray Kacaankii Warshadaha, oo ay weheliso ikhtiraacida iyo adeegsiga matoorka uumiga, dhuxusha waxaa si weyn loogu isticmaalaa shidaal warshadeed waxayna bulshada u keentay awoodo wax soo saar oo aad u badan oo aan hore loo arag.
Codsiga Dhuxusha
Dhuxusha Shiinaha waxaa loo qaybiyaa toban qaybood. Guud ahaan, dhuxusha caatada ah, dhuxusha kookaynta, dhuxusha dufanka leh, dhuxusha gaaska, dhuxusha isku xiran ee daciifka ah, aan xidhnayn iyo tan ololka dheer waxaa si wadajir ah loogu yeeraa dhuxusha bituminous; dhuxusha caatada ah waxaa loogu yeeraa semi Anthracite; Haddii waxa ku jira isbeddelka uu ka badan yahay 40%, waxaa loo yaqaan lignite.

Lignite:
Inta badan waa weyn yahay, bunni madow, dhalaal madow, qaab-dhismeed dabacsan; Waxay ka kooban tahay qiyaastii 40% walxo isbeddela, meel dab-shid yar leh iyo dab-qabad fudud. Guud ahaan waxaa loo isticmaalaa gaaska, warshadaha dareeraha, kuleyliyaha korontada, iwm.
Dhuxul Bitumin ah:
Guud ahaan waa budo, yar oo budo ah, inta badan waa madow oo dhalaalaya, qaab dhismeed fiican leh, oo ka kooban in ka badan 30% walxo isbeddelaya, meel dab-shid yar leh oo si fudud loo shidi karo; Dhuxusha bituminous-ka badankood waa dhegdheg oo si fudud loo shidi karo inta lagu jiro gubashada. Waxaa loo isticmaalaa warshadaha coking, isku-darka dhuxusha, kuleyliyaha korontada iyo gaaska.
Antracit:
Waxaa jira laba nooc oo budo ah iyo qaybo yaryar, kuwaas oo ah madow, bir ah oo dhalaalaya. Wasakh yar, qaab-dhismeed isku dhafan, kaarboon go'an oo sarreeya, ilaa in ka badan 80%; Waxyaabaha kacsan waa hooseeyaa, ka hooseeya 10%, barta dab-shidku waa sarreysaa, mana fududa in dab la qabto. Qaddar ku habboon oo dhuxul iyo ciid ah ayaa lagu dari doonaa gubashada si loo yareeyo xoogga dabka. Waxaa loo isticmaali karaa in lagu sameeyo gaas ama si toos ah shidaal ahaan.
Socodka habka dhuxusha ee la shiido
Shiididda dhuxusha, waxay inta badan ku salaysan tahay isku-dhafka shiididda Harzburg. Inta uu weyn yahay isku-dhafka shiididda Harzburg, shiididda ayaa ka sii wanaagsan (≥ 65), iyo inta uu yar yahay isku-dhafka shiididda Harzburg, way adkaanaysaa shiididda (55-60).
Faallooyin:
① dooro mashiinka ugu weyn sida waafaqsan shuruudaha wax soo saarka iyo fineness;
② Codsiga ugu muhiimsan: dhuxusha la shiiday ee kulaylka leh
Falanqaynta moodooyinka shiididda shiididda
1. Warshadda Pendulum (HC, HCQ taxane dhuxul la shiiday):
Kharash maalgashi oo hooseeya, wax soo saar sare, isticmaalka tamarta oo hooseeya, qalab deggan iyo buuq yar; Khasaaraha ayaa ah in kharashka hawlgalka iyo dayactirka uu ka sarreeyo kan warshadda toosan.

Mashruucu waa in la bixiyo dhuxul la shiiday oo loogu talagalay kuleyliyaha dhuxusha ee nidaamka kuleyliyaha dhulka hoostiisa mara ee Bulianta oo ah koox. Qandaraaslaha guud ee mashruuca waa Akadeemiyada Sayniska Dhuxusha ee Shiinaha. Tan iyo 2009, Akadeemiyada Sayniska Dhuxusha ee Shiinaha waxay ahayd lammaane istaraatiiji ah oo Hongcheng ah iyo isbahaysi xooggan. Dhammaan mashaariicda kuleyliyaha dhuxusha ee shiiday iyo dhuxusha la shiday waxay qaateen warshadda shiiday ee Hongcheng si loogu waafajiyo nidaamka. Lixdii sano ee la soo dhaafay, Hongcheng waxay si daacad ah ula shaqeysay Akadeemiyada Sayniska Dhuxusha, mashaariicda burburinta dhuxusha ee shiidayna waxay ku faafeen dhammaan meelaha ugu muhiimsan ee laga soo saaro dhuxusha ee Shiinaha. Mashruucu wuxuu qaataa saddex qaybood oo warshadood oo Raymond ah oo leh nidaamka wareegga furan ee HC1700, kuwaas oo si gaar ah loogu talagalay in lagu shiido dhuxusha la shiiday. Warshadda shiididda dhuxusha ee shiiday ee Hc1700 waxay qaadataa wareegga furan, rakibidda qalabka aan qarxin iyo tallaabooyin kale, nidaamkuna waa ammaan oo la isku halleyn karo. Wax soo saarka warshadda HC1700 waa 30-40% ka sarreeya kan warshadda shiididda ee pendulum-ka dhaqameed, taas oo badbaadinaysa tamarta iyo deegaanka u fiican.
