Taw qhia rau Coal
Coal yog ib hom carbonized fossil ntxhia.Nws yog tsim los ntawm carbon, hydrogen, oxygen, nitrogen thiab lwm yam ntsiab lus, feem ntau siv los ua roj los ntawm tib neeg.Tam sim no, cov thee muaj 63 npaug ntawm kev tshawb nrhiav khaws cia ntau dua li cov roj av.Coal hu ua dub kub thiab cov khoom noj ntawm kev lag luam, yog lub zog loj txij li xyoo pua 18th.Thaum lub sij hawm Industrial Revolution, nrog rau kev tsim thiab kev siv lub tshuab hluav taws xob, thee tau dav siv los ua cov roj ua lag luam thiab coj cov khoom lag luam loj loj uas tsis tau muaj dua los rau tib neeg.
Kev siv thee
Tuam Tshoj cov thee tau muab faib ua kaum pawg.Feem ntau, lean thee, coking thee, fat thee, gas thee, weakly cohesive, unbonded and long flame coal are collectively referred to as bituminous thee;Lean thee hu ua semi Anthracite;Yog tias cov ntsiab lus tsis hloov pauv ntau dua 40%, nws hu ua lignite.
Coal classification table (tsuas yog coking thee)
| Qeb | Mos thee | Meager thee | Lean thee | Coking thee | Roj thee | Gas thee | Tsis muaj daim ntawv cog lus thee | Tsis yog-bond coal | Nplaim taws ntev | Xim av thee |
| Volatility | 0 ~ 10 | > 10 ~ 20 | > 14-20 | 14-30 Nws | 26-37 : kuv | > 30 | > 20-37 | > 20-37 | > 37 | > 40 |

Lignite:
Feem ntau loj, tsaus xim av, tsaus luster, xoob kev ntxhib los mos;Nws muaj txog 40% cov teeb meem tsis hloov pauv, tsis tshua muaj hluav taws xob taw tes thiab yooj yim kom ntes hluav taws.Nws feem ntau yog siv rau hauv gasification, liquefaction kev lag luam, fais fab boiler, thiab lwm yam.
Bituminous thee:
Nws yog feem ntau granular, me me thiab hmoov, feem ntau yog xim dub thiab ci, nrog kev ntxhib los mos, muaj ntau dua 30% cov teeb meem tsis haum, tsis tshua muaj qhov taw tes thiab yooj yim rau ignite;Feem ntau bituminous coals yog nplaum thiab yooj yim rau slag thaum combustion.Nws yog siv nyob rau hauv coking, thee blending, fais boiler thiab gasification kev lag luam.
Anthracite:
Muaj ob hom hmoov thiab me me, uas yog xim dub, xim hlau thiab ci iab.Tsawg impurities, kev ntxhib los mos, siab ruaj khov cov ntsiab lus, txog li 80%;Cov ntsiab lus volatile tsawg, qis dua 10%, qhov taw tes hluav taws kub yog siab, thiab nws tsis yooj yim rau ntes hluav taws.Qhov tsim nyog ntawm cov thee thiab av yuav tsum tau ntxiv rau kev sib xyaw kom txo tau qhov hluav taws kub.Nws tuaj yeem siv los ua roj lossis ncaj qha ua roj.
Txheej txheem ntws ntawm thee pulverization
Rau thee sib tsoo, nws yog tsuas yog raws li nws cov Harzburg grindability coefficient.Qhov loj dua Harzburg grindability coefficient, qhov zoo dua qhov sib tsoo (≥ 65), thiab qhov me me ntawm Harzburg grindability coefficient, qhov sib tsoo nyuaj (55-60).
Lus ceeb toom:
① xaiv lub tshuab tseem ceeb raws li cov khoom tsim tawm thiab kev ua kom zoo;
② Daim ntawv thov tseem ceeb: thermal pulverized thee
Kev tsom xam ntawm kev sib tsoo zeb qauv
1. Pendulum zeb (HC, HCQ series pulverized thee zeb):
Tus nqi qis peev, siab tso zis, tsis tshua muaj zog noj, khoom siv ruaj khov thiab tsis muaj suab nrov;Qhov tsis zoo yog tias kev ua haujlwm thiab kev saib xyuas tus nqi siab dua li ntawm ntsug zeb.

Lus Cim (qhov tseem ceeb configuration):
① Hongcheng patented qhib Circuit Court system yog saws rau lignite thiab ntev nplaim taws coal nrog siab volatility.
② Lub paj paj ntoo nrog ntsug pendulum qauv txais lub tes tsho qauv, uas muaj txiaj ntsig zoo dua.
③ Cov khoom pov thawj tawg yog tsim los rau lub kaw lus.
④ Plua plav collector thiab pipeline yuav tsum tau tsim kom tsis txhob muaj plua plav tsub zuj zuj ntawm lub kaum sab xis kom deb li deb tau.
⑤ Rau hmoov conveying system, nws raug nquahu kom cov neeg siv khoom siv cov pa xa tawm thiab ua kom muaj kev nyab xeeb ntxiv nitrogen conveying thiab nitric oxide detection system.
2. Vertical thee zeb (HLM ntsug coal zeb):
High tso zis, loj-scale ntau lawm, tsis tshua muaj txij nkawm tus nqi, high degree ntawm automation thiab mature kub cua tshuab.Qhov tsis zoo yog tus nqi peev siab thiab thaj chaw loj hauv pem teb.

Theem I:Crushing ntawm raw khoom
Qhov lojTheecov khoom yog crushed los ntawm lub crusher mus rau lub pub fineness (15mm-50mm) uas tuaj yeem nkag mus rau hauv kev sib tsoo zeb.
TheemII: Gnkim
Lub crushedTheeCov ntaub ntawv me me raug xa mus rau lub hopper cia los ntawm lub elevator, thiab tom qab ntawd xa mus rau qhov sib tsoo chamber ntawm lub zeb sib npaug thiab ntau npaum li cas los ntawm feeder rau kev sib tsoo.
Theem III:Muab faibhauv
Cov ntaub ntawv milled tau muab qhab nia los ntawm kev muab qhab nia, thiab cov hmoov tsis tsim nyog tau muab qhab nia los ntawm cov khoom faib thiab rov qab mus rau lub tshuab tseem ceeb rau kev sib tsoo.
TheemV: Collection ntawm cov khoom tiav
Cov hmoov ua raws li kev nplua nuj ntws los ntawm cov raj xa dej nrog cov roj thiab nkag mus rau hauv cov plua plav collector rau kev sib cais thiab sib sau.Cov hmoov uas tau sau tiav yog xa mus rau cov khoom tiav silo los ntawm cov khoom siv thauj khoom los ntawm qhov chaw nres nkoj tawm, thiab tom qab ntawd ntim los ntawm cov hmoov tanker lossis tsis siv neeg ntim khoom.
