Intshayelelo ngamalahle
Amalahle luhlobo lweminerali ye-carbonized fossil.Ihlelwe yikhabhoni, ihydrogen, ioksijini, initrogen kunye nezinye izinto, uninzi olusetyenziswa njengamafutha ngabantu.Okwangoku, amalahle anomthamo oyi-63 womthamo ohlolisisiweyo kune-petroleum.Amalahle abizwa ngokuba yigolide emnyama kunye nokutya kweshishini, yeyona nto inamandla ukusukela ngenkulungwane ye-18.Ngexesha leNguqulelo yezoShishino, kunye nokuyilwa kunye nokusetyenziswa kwe-injini yomphunga, amalahle asetyenziswa kakhulu njengamafutha emizi-mveliso kwaye azisa amandla amakhulu angazange abonwe ngaphambili eluntwini.
Ukusetyenziswa kwamalahle
Amalahle aseTshayina ahlulwe abe ziindidi ezilishumi.Ngokuqhelekileyo, amalahle abhityileyo, amalahle okuphekela, amalahle atyebileyo, amalahle egesi, ubumbano olubuthathaka, olungabotshwanga kunye namalahle omlilo amade abizwa ngokudibeneyo njengamalahle e-bituminous;Amalahle abhityileyo abizwa ngokuba yisemi Anthracite;Ukuba umxholo oguquguqukayo mkhulu kune-40%, ubizwa ngokuba yi-lignite.
Itheyibhile yokuhlelwa kwamalahle (ingakumbi amalahle okuphekelwa)

Lignite:
Ubukhulu becala obukhulu, buntsundu, bubumnyama bubengezela, ubume obuxengayo;Iqulethe malunga ne-40% yezinto eziguquguqukayo, indawo yokutshisa ephantsi kwaye kulula ukubamba umlilo.Ngokuqhelekileyo isetyenziswa kwi-gasification, i-liquefaction industry, ibhoyili yamandla, njl.
Amalahle eBituminous:
Ngokuqhelekileyo igranular, encinci kunye nomgubo, ubukhulu becala imnyama kwaye iyabengezela, inokwakheka okuhle, iqulethe ngaphezulu kwe-30% yezinto eziguquguqukayo, indawo yokutshisa ephantsi kwaye kulula ukuyitshisa;Uninzi lwamalahle e-bituminous ancangathi kwaye kulula ukuwabeka ngexesha lokutsha.Isetyenziswa kwi-coking, ukudibanisa amalahle, kwibhoyila yamandla kunye neshishini lokufakwa kwegesi.
I-anthracite:
Kukho iindidi ezimbini zomgubo kunye namaqhekeza amancinci, amnyama, esinyithi kunye nemenyezelayo.Ukungcola okuncinci, ukuthungwa kwe-compact, umxholo ophezulu wekhabhoni osisigxina, ukuya kuthi ga kwi-80%;Umxholo oguquguqukayo uphantsi, ngaphantsi kwe-10%, indawo yokutshisa iphezulu, kwaye akulula ukubamba umlilo.Umlinganiselo ofanelekileyo wamalahle nomhlaba uya kongezwa ukuze uvuthe ukuze kucuthwe ubushushu bomlilo.Ingasetyenziselwa ukwenza igesi okanye ngokuthe ngqo njengamafutha.
Inkqubo yokuhamba ngokucolwa kwamalahle
Ukusila amalahle, isekelwe ikakhulu kwi-Harzburg grindability coefficient.Ubukhulu be-Harzburg grindability coefficient, ngcono ukugaya (≥ 65), kunye ne-Harzburg grindability coefficient encinci, kunzima ukugaya (55-60).
Amagqabantshintshi:
① khetha umatshini ophambili ngokwemveliso kunye neemfuno zokulunga;
② Isicelo esiphambili: amalahle acoliweyo ashushu
Uhlalutyo kwiimodeli zokusila
1. Ilitye lokusila iPendulum (HC, HCQ series pulverized coal mill):
Ixabiso eliphantsi lotyalo-mali, imveliso ephezulu, ukusetyenziswa kwamandla aphantsi, izixhobo ezizinzileyo kunye nengxolo ephantsi;I-drawback yeyokuba iindleko zokusebenza kunye nokugcinwa ziphezulu kunelo lokusila elithe nkqo.

Amagqabantshintshi (uqwalaselo olungundoqo):
① Inkqubo yesekethe evulelekileyo yaseHongcheng yamkelwe i-lignite kunye namalahle amadangatye amade anokuguquka okukhulu.
② Isakhelo sentyatyambo yeplum enesakhiwo se-pendulum esithe nkqo samkela isakhiwo semikhono, esinesiphumo esingcono.
③ Isixhobo sobungqina bokudubula siyilelwe inkqubo.
④ Umqokeleli wothuli kunye nombhobho uya kuyilwa ukunqanda ukufumba kothuli kwikona efileyo kangangoko kunokwenzeka.
⑤ Kwinkqubo yokuhambisa umgubo, kucetyiswa ukuba abathengi bamkele ukugqithiswa kwegesi kwaye bongeze ngokwemeko i-nitrogen yokuhambisa kunye nenkqubo yokubona i-nitric oxide.
2. Ilitye lokusila elithe nkqo (i-HLM yokusila nkqo yamalahle):
Imveliso ephezulu, imveliso enkulu, izinga lokugcinwa okuphantsi, iqondo eliphezulu lokuzisebenzela kunye nobuchwepheshe bomoya oshushu ovuthiweyo.Ukungalungi ziindleko eziphezulu zotyalo-mali kunye nomgangatho omkhulu.
Ukucaciswa kunye neeparitha zobugcisa ze-HLM ecoliweyo yokusila yamalahle ethe nkqo (ishishini lesinyithi)
