Kev Taw Qhia Txog Thee
Thee yog ib hom pob zeb fossil uas muaj carbonized. Nws tau teeb tsa los ntawm carbon, hydrogen, oxygen, nitrogen thiab lwm yam ntsiab lus, feem ntau siv los ua roj los ntawm tib neeg. Tam sim no, thee muaj 63 npaug ntawm cov khoom siv tshawb nrhiav ntau dua li roj av. Thee tau raug hu ua kub dub thiab cov zaub mov ntawm kev lag luam, yog lub zog tseem ceeb txij li xyoo pua 18th. Thaum lub sijhawm Kev Hloov Pauv Kev Lag Luam, nrog rau kev tsim thiab siv lub cav ua pa, thee tau siv dav ua roj kev lag luam thiab coj cov zog tsim khoom loj heev rau lub zej zog.
Daim Ntawv Thov ntawm Thee
Cov thee hauv Suav teb muaj kaum pawg. Feem ntau, cov thee lean, cov thee coking, cov thee roj, cov thee roj tsis sib haum, tsis sib txuas thiab cov thee nplaim ntev yog hu ua bituminous thee; cov thee lean hu ua semi Anthracite; Yog tias cov ntsiab lus volatile ntau dua 40%, nws hu ua lignite.

Lignite:
Feem ntau yog loj heev, xim av tsaus, ci ntsa iab, xoob xoob; Nws muaj li ntawm 40% cov khoom uas yaj tau yooj yim, qhov kub qis thiab yooj yim rau hluav taws. Nws feem ntau yog siv rau hauv kev ua roj, kev lag luam ua kua, lub boiler fais fab, thiab lwm yam.
Cov thee bituminous:
Feem ntau nws yog granular, me me thiab hmoov, feem ntau yog dub thiab ci, nrog cov qauv zoo, muaj ntau dua 30% volatile khoom, qis ignition point thiab yooj yim rau ignite; Feem ntau bituminous thee yog nplaum thiab yooj yim rau slag thaum lub sij hawm combustion. Nws yog siv rau hauv coking, thee blending, fais fab boiler thiab gasification kev lag luam.
Anthracite:
Muaj ob hom hmoov thiab tej daim me me, uas yog xim dub, xim hlau thiab ci ntsa iab. Tsawg dua cov khoom tsis huv, cov qauv me me, cov pa roj carbon ruaj khov siab, txog li ntau dua 80%; Cov ntsiab lus volatile qis, qis dua 10%, qhov chaw hluav taws kub siab, thiab nws tsis yooj yim rau hluav taws. Yuav tsum ntxiv cov thee thiab av kom txaus rau kev sib xyaw kom txo qhov hluav taws kub. Nws tuaj yeem siv los ua roj lossis ncaj qha ua roj.
Cov txheej txheem ntws ntawm cov thee pulverization
Rau kev sib tsoo thee, nws yog raws li nws cov Harzburg grindability coefficient. Qhov loj dua ntawm Harzburg grindability coefficient, qhov zoo dua qhov sib tsoo (≥ 65), thiab qhov me dua ntawm Harzburg grindability coefficient, qhov nyuaj dua qhov sib tsoo (55-60).
Cov Lus Cim:
① xaiv lub tshuab tseem ceeb raws li qhov tso zis thiab qhov zoo tshaj plaws;
② Daim ntawv thov tseem ceeb: thermal pulverized thee
Kev tshuaj xyuas ntawm cov qauv sib tsoo
1. Lub tshuab zeb Pendulum (HC, HCQ series lub tshuab zeb thee pulverized):
Tus nqi qis rau kev nqis peev, cov zis siab, kev siv hluav taws xob tsawg, cov khoom siv ruaj khov thiab suab nrov tsawg; Qhov tsis zoo yog tias tus nqi ua haujlwm thiab kev saib xyuas siab dua li ntawm cov zeb ntsug.

Cov Lus Cim (kev teeb tsa tseem ceeb):
① Hongcheng patented qhib circuit system yog saws rau lignite thiab ntev nplaim thee nrog siab volatility.
② Lub thav duab paj ntoo plum nrog cov qauv pendulum ntsug siv cov qauv tes tsho, uas muaj cov txiaj ntsig zoo dua.
③ Cov khoom siv tiv thaiv kev tawg yog tsim los rau lub kaw lus.
④ Lub tshuab sau hmoov av thiab cov kav dej yuav tsum tsim los kom tsis txhob muaj cov hmoov av sib sau ua ke ntau li ntau tau.
⑤ Rau cov hmoov xa khoom, nws raug pom zoo kom cov neeg siv khoom siv roj xa khoom thiab ntxiv cov nitrogen xa khoom thiab nitric oxide nrhiav system.
2. Lub tshuab zeb thee ntsug (HLM lub tshuab zeb thee ntsug):
Cov zis siab, kev tsim khoom ntau, kev saib xyuas tsawg, qib siab ntawm kev siv tshuab thiab kev siv tshuab cua kub paub tab. Qhov tsis zoo yog tus nqi peev siab thiab thaj chaw hauv pem teb loj.

Theem I:Ckev siv cov khoom siv raw
Qhov lojTheeCov khoom siv raug tsoo los ntawm lub crusher kom txog thaum qhov pub mis zoo (15mm-50mm) uas tuaj yeem nkag mus rau hauv lub tshuab sib tsoo.
TheemII: Gkev ua kom tawv
Qhov raug tsooTheeCov ntaub ntawv me me raug xa mus rau lub hopper cia khoom los ntawm lub elevator, thiab tom qab ntawd xa mus rau chav sib tsoo ntawm lub zeb kom sib npaug thiab ntau los ntawm lub feeder rau kev sib tsoo.
Theem III:Faib pawgkev ua
Cov ntaub ntawv milled raug ntsuas los ntawm lub tshuab ntsuas qib, thiab cov hmoov tsis tsim nyog raug ntsuas los ntawm lub classifier thiab xa rov qab mus rau lub tshuab tseem ceeb rau kev sib tsoo dua.
TheemV: Ckev sau cov khoom tiav lawm
Cov hmoov uas ua raws li qhov zoo yuav ntws los ntawm cov kav dej nrog cov roj thiab nkag mus rau hauv lub tshuab nqus plua plav kom sib cais thiab sau. Cov hmoov uas sau tau tiav lawm yuav raug xa mus rau lub silo ntawm cov khoom tiav lawm los ntawm lub cuab yeej xa khoom los ntawm qhov chaw tawm, thiab tom qab ntawd ntim los ntawm lub tanker hmoov lossis lub tshuab ntim khoom tsis siv neeg.
Cov piv txwv ntawm kev siv cov hmoov thee ua
Tus qauv thiab tus lej ntawm cov khoom siv no: 3 pawg ntawm HC1700 qhib lub voj voog sib tsoo tshuab
Ua cov khoom siv raw: Anthracite
Qhov zoo ntawm cov khoom tiav: 200 mesh D92
Cov Khoom Siv Muaj Peev Xwm: 8-12 tons / teev
Qhov project no yog los muab cov thee uas raug hlawv rau lub boiler uas siv thee hlawv ntawm lub tshuab cua sov hauv av hauv Bulianta lub chaw khawb thee ntawm ib pawg. Tus neeg cog lus dav dav ntawm qhov project yog China Academy of Coal Sciences. Txij li xyoo 2009, Chinese Academy of Coal Sciences tau yog tus khub koom tes zoo ntawm Hongcheng thiab yog ib lub koom haum muaj zog. Txhua qhov project boiler uas siv thee hlawv thiab cov thee uas raug hlawv siv Hongcheng lub tshuab sib tsoo rau kev sib phim. Tau 6 xyoo dhau los, Hongcheng tau koom tes nrog Academy of Coal Sciences, thiab cov project pulverized thee pulverizing tau kis mus thoob plaws thaj chaw tsim thee tseem ceeb hauv Suav teb. Qhov project no siv peb pawg ntawm Raymond mills nrog HC1700 lub tshuab qhib hluav taws xob, uas tau tsim tshwj xeeb rau kev sib tsoo thee uas raug hlawv. Hc1700 lub tshuab sib tsoo thee uas raug hlawv siv lub tshuab qhib hluav taws xob, kev teeb tsa cov cuab yeej tiv thaiv kev tawg thiab lwm yam kev ntsuas, thiab lub system muaj kev nyab xeeb thiab txhim khu kev qha. Cov zis ntawm HC1700 lub tshuab sib tsoo yog 30-40% siab dua li ntawm cov tshuab sib tsoo pendulum ib txwm muaj, uas txuag hluav taws xob thiab zoo rau ib puag ncig.
