Hordhaca Dhuxusha
Dhuxul dhagaxdu waa nooc ka mid ah macdanta kaarboonaysan.Waxaa habeeya kaarboon, hydrogen, oksijiin, nitrogen iyo walxo kale, kuwaas oo badi dadku u isticmaalo shidaal ahaan.Waqtigan xaadirka ah, dhuxushu waxay leedahay 63 jeer mugga kaydka la sahamiyey marka loo eego batroolka.Dhuxusha waxaa loo yaqaan dahabka madow iyo cuntada warshadaha, waa tamarta ugu weyn tan iyo qarnigii 18aad.Intii lagu jiray Kacaankii Warshadaha, oo ay weheliso hal-abuurka iyo adeegsiga mishiinnada uumiga, dhuxusha waxa si weyn loogu isticmaalaa shidaalka warshadaha oo waxa ay bulshada u keentay xoog wax-soo-saar weyn oo aan hore loo arag.
Codsiga Dhuxusha
Dhuxusha Shiinaha waxa ay u qaybsantaa toban qaybood.Guud ahaan, dhuxusha caatada ah, dhuxusha coking, dhuxusha baruurta, dhuxusha gaaska, si daciif ah isku xidhan, aan xidhnayn iyo dhuxusha olol dheer ayaa si wada jir ah loo tixraacaa sida bituminous dhuxusha;Dhuxusha caatada ah waxaa loo yaqaan semi Anthracite;Haddii waxa ku jira isbeddelku uu ka weyn yahay 40%, waxa loo yaqaan lignite.

Linite:
Badanaa baaxad weyn, madow madow, dhalaal madow, muuqaal dabacsan;Waxay ka kooban tahay qiyaastii 40% walxo is-bedbeddelaya, bar shid yar oo si fudud dab loo qabsado.Waxaa guud ahaan loo isticmaalaa gaaska, warshadaha liquefaction, kululeeyaha korontada, iwm.
Dhuxul bituminous:
Guud ahaan waa granular, yar iyo budo, inta badan madow iyo dhaldhalaalaan, oo leh muuqaal wanaagsan, oo ka kooban wax ka badan 30% walxo aan degganeyn, dhibicda dabka yar oo sahlan in la shido;Inta badan dhuxusha bituminous waa kuwo dhegdheg leh oo ay fududahay in la dhufto inta lagu jiro gubashada.Waxaa loo isticmaalaa coking, isku dhafka dhuxusha, kuleyliyaha tamarta iyo warshadaha gaaska.
Anthracite:
Waxaa jira laba nooc oo budo ah iyo qaybo yaryar, kuwaas oo ah madow, macdan iyo dhalaalaya.Wasakhda yar, qaabka is haysta, kaarboonka kaarboonka ee sarreeya, ilaa in ka badan 80%;Nuxurka isbedbeddelaya waa hooseeyaa, ka hooseeya 10%, barta shidashadu waa sarraysaa, mana fududa in dab la qabsado.Xaddi ku habboon oo dhuxul iyo carro ah waa in lagu daraa gubashada si loo yareeyo xoogga dabka.Waxaa loo isticmaali karaa in lagu sameeyo gaas ama si toos ah shidaal ahaan.
Geedi socodka socodka dhuxusha
Shiididda dhuxusha, waxay inta badan ku salaysan tahay isku-dheellitirnaanteeda Harzburg.Inta uu sii weynaado isku-xidhka-shiidida Harzburg, ayaa si fiican u shiidi doona (≥ 65), iyo inta yar ee isku-dheellitirnaanta Harzburg, way sii adkaanaysaa shiididda (55-60).

② Codsiga ugu muhiimsan: dhuxusha kulaylka leh
Falanqaynta moodooyinka shiididda
1. Qalab-shiid kiimikaad (HC, HCQ taxane ah oo la miiray dhuxusha):
Qiimaha maalgashiga hooseeya, wax soo saarka sare, isticmaalka tamarta hooseeya, qalabka xasilloon iyo qaylada hoose;Cilad-xumada ayaa ah in kharashka hawlgalka iyo dayactirku uu ka sarreeyo kan shiidka toosan.

Hadallo (qaabaynta ugu weyn):
① Nidaamka wareegga furan ee patented Hongcheng waxaa loo ansixiyay lignite iyo dhuxusha ololka dheer oo leh isbedel sare.
② Qaabka ubaxa plum ee leh qaab-dhismeedka pendulum-ka toosan wuxuu qaataa qaab-dhismeedka gacanta, kaas oo leh saameyn wanaagsan.
③ Aaladda ka hortagta qaraxa waxaa loogu talagalay nidaamka.
④ Boodhka ururiyaha iyo dhuumaha waa in loo qaabeeyaa si looga fogaado in meel dhinta ay ku ururto boodhka ilaa inta suurtogalka ah.
⑤ Nidaamka gudbinta budada, waxaa lagula talinayaa in macaamiishu qaataan gaaska gudbinta oo ay shuruud ku daraan gudbinta nitrogen iyo nidaamka ogsaydhka nitric oxide.
2. Dhuxul-dhagax toosan (HLM mill dhuxul toosan):
Wax-soo-saarka sare, wax-soo-saarka baaxadda weyn, heerka dayactirka oo hooseeya, heer sare oo otomaatig ah iyo farsamada hawada kulul ee qaan-gaadhka ah.Khasaaradu waa kharash maalgashi oo sarreeya iyo dhul ballaadhan.
