Nhanganyaya kuMazimbe
Marasha imhando yecarbonized fossil mineral.Yakarongwa nekabhoni, hydrogen, okisijeni, nitrogen uye zvimwe zvinhu, mazhinji anoshandiswa sehuni nevanhu.Parizvino, marasha aya ane nguva 63 yevhoriyamu yakaongororwa kupfuura petroleum.Marasha ainzi goridhe dema uye chikafu cheindasitiri, ndiro simba guru kubva muzana ramakore rechi18.Munguva yeRevolution Revolution, pamwe nekugadzirwa uye kushandiswa kweinjini yehutsi, marasha anoshandiswa zvakanyanya semafuta emumaindasitiri uye akaunza masimba makuru asina kumboitika kunharaunda.
Kushandiswa kweMarasha
Marasha ekuChina akakamurwa kuita zvikamu gumi.Kazhinji, marasha akaonda, coking marasha, marasha ane mafuta, gasi marasha, asina kusimba akabatana, asina kusungwa uye marefu emoto marasha anounganidzwa pamwe chete anonzi bituminous marasha;Marasha akaonda anonzi semi Anthracite;Kana iyo inoputika yemukati yakakura kupfuura 40%, inonzi lignite.

Lignite:
Kazhinji yakakura, yakasvibira, yakasviba kupenya, yakasununguka magadzirirwo;Iine inenge 40% inoshanduka zvinhu, nzvimbo yakaderera yekubatidza uye iri nyore kubata moto.Iyo inowanzo shandiswa mugasification, liquefaction indasitiri, magetsi boiler, nezvimwe.
Bituminous marasha:
Inowanzoita granular, diki uye upfu, kazhinji dema uye inopenya, ine magadzirirwo akanaka, ine zvinopfuura 30% zvinhu zvinoputika, nzvimbo yakaderera yekubatidza uye nyore kubatidza;Marasha mazhinji ane bituminous anonamira uye ari nyore kudonha panguva yekupisa.Inoshandiswa mukubika, kusanganisa marasha, magetsi boiler uye gasification indasitiri.
Anthracite:
Kune marudzi maviri ehupfu nezvidimbu zvidiki zvinova zvitema, simbi nezvinopenya.Zvishoma kusvibiswa, compact texture, yakakwirira yakagadziriswa kabhoni yemukati, inosvika kupfuura 80%;Izvo zvinoputika zvemukati zvakaderera, pazasi pe10%, nzvimbo yekubatidza yakakwira, uye hazvisi nyore kubata moto.Huwandu hwakakodzera hwemarasha nevhu huchawedzerwa pakupisa kuti moto uderedze.Inogona kushandiswa kugadzira gasi kana zvakananga sehuni.
Nzira yekuyerera kwemarasha pulverization
Pakukuya marasha, inonyanya kuenderana neiyo Harzburg grindability coefficient.Iyo yakakura iyo Harzburg grindability coefficient, zviri nani kukuya (≥ 65), uye iyo diki yeHarzburg grindability coefficient, yakanyanya kuoma kugaya (55-60).

① sarudza muchina mukuru zvinoenderana nekubuda uye kunaka zvinodiwa;
② Chikumbiro chikuru: marasha anopisa anopisa
Ongororo pazvigayo mhando
1. Pendulum chigayo (HC, HCQ dzakatevedzana pulverized marasha chigayo):
Mutengo wakaderera wekudyara, kuburitsa kwakanyanya, kuderera kwesimba rekushandisa, yakagadzikana michina uye yakaderera ruzha;Chinonetsa ndechekuti mari yekushanda nekugadzirisa yakakwira kudarika yeguyo rakamira.
