Nhanganyaya kuMarasha
Marasha imhando yezvicherwa zvemafossil zvakakangwa. Yakarongwa nekabhoni, hydrogen, okisijeni, nitrogen nezvimwe zvinhu, zvizhinji zvacho zvichishandiswa semafuta nevanhu. Parizvino, marasha ane huwandu hwakachengetwa hwakapetwa ka63 kupfuura peturu. Marasha ainzi goridhe dema uye chikafu chemaindasitiri, ndiyo simba guru kubvira muzana remakore rechi18. Munguva yeIndustrial Revolution, pamwe chete nekugadzirwa nekushandiswa kweinjini dzemhepo, marasha anoshandiswa zvakanyanya semafuta emaindasitiri uye akaunza simba guru risati ramboonekwa rekubudirira munharaunda.
Kushandiswa kweMarasha
Marasha eChina akakamurwa kuita zvikamu gumi. Kazhinji, marasha asina mafuta akawanda, marasha emafuta, marasha egasi, marasha asina simba, asina kusungwa uye marasha emurazvo murefu anonzi marasha ekubitura; marasha asina mafuta akawanda anonzi semi Anthracite; Kana huwandu hwemarasha huchipfuura 40%, hunonzi lignite.

Ruvara rwakatsetseka:
Kazhinji yakakura, yebrown yakasviba, ine kupenya kwakasviba, ine magadzirirwo akasununguka; Ine zvinhu zvinoshanduka zvinosvika 40%, ine pokubatidza shoma uye iri nyore kubata moto. Inowanzoshandiswa mukugadzira gasi, indasitiri yekunyungudutsa mvura, bhoira remagetsi, nezvimwewo.
Marasha eBituminous:
Kazhinji kacho kanenge kakaita granular, kadiki uye kakaita seupfu, kakawanda kacho katema uye kanopenya, kane magadzirirwo akapfava, kane zvinhu zvinoshanduka zvinodarika 30%, nzvimbo yekubatidza yakaderera uye zviri nyore kubatidza; Marasha mazhinji ebituminous anonamira uye ari nyore kudonhedza kana apiswa. Anoshandiswa mukugadzira coking, coal blending, power boiler uye gasification industry.
Anthracite:
Kune mhando mbiri dzeupfu nezvidimbu zvidiki, zvitema, zvesimbi uye zvinopenya. Kusachena kushoma, magadzirirwo akamanikana, huwandu hwakawanda hwekabhoni hwakagadzika, hunosvika kupfuura 80%; Kusagadzikana kwemhepo kwakaderera, pasi pe10%, nzvimbo yekubatidza moto yakakwira, uye hazvisi nyore kubata moto. Huwandu hwakakodzera hwemarasha nevhu zvinofanirwa kuwedzerwa kuti zvitsve kuti moto uderedzwe. Inogona kushandiswa kugadzira gasi kana semafuta zvakananga.
Kufamba kwemaitiro ekupwanya marasha
Pakukuya marasha, inonyanya kuenderana neHarzburg grindability coefficient yayo. Kana Harzburg grindability coefficient yakakura, grinda yacho iri nani (≥ 65), uye kana Harzburg grindability coefficient iri diki, grinda yacho inoomawo (55-60).
Mashoko:
① Sarudza muchina mukuru zvichienderana nezvinodiwa pakubuda uye kunaka kwawo;
② Main application: marasha anopiswa nekupisa
Ongororo yemamodheru ekugaya
1. Chigayo chePendulum (HC, chigayo chemarasha chakakuyiwa cheHCQ):
Mari shoma yekudyara, simba rakawanda rinobuda, simba shoma rinoshandiswa, michina yakagadzikana uye ruzha rwakaderera; Dambudziko nderekuti mari yekushandisa nekugadzirisa yakakwira kupfuura yemichina yakamira.

Chirongwa ichi ndechekupa marasha akakuyiwa echitofu chepasi pevhu cheBulianta coal mine cheboka. Mukondirakita mukuru wechirongwa ichi iChina Academy of Coal Sciences. Kubva muna 2009, Chinese Academy of Coal Sciences yave iri shamwari yeHongcheng uye iri mushandirapamwe wakasimba. Mapurojekiti ese echitofu chemarasha nemapurojekiti emarasha akakuyiwa anoshandisa chigayo chekukuya cheHongcheng kuti chifanane nesystem. Mumakore matanhatu apfuura, Hongcheng yakashanda pamwe chete neAcademy of Coal Sciences, uye mapurojekiti ekupuruzira marasha akakuyiwa akapararira munzvimbo huru dzekugadzira marasha muChina. Chirongwa ichi chinoshandisa seti nhatu dzeRaymond mills dzine HC1700 open circuit system, dzakagadzirirwa kupuruzira marasha akakuyiwa. Hc1700 pulverized coal grinding mill inoshandisa open circuit, kuisa mudziyo unodzivirira kuputika nezvimwe zviyero, uye system yacho yakachengeteka uye yakavimbika. Kubuda kweHC1700 mill kwakakwira ne30-40% kupfuura kweyechinyakare pendulum grinding mill, iyo inochengetedza simba uye isingakuvadzi nharaunda.
