Kev Xaiv Hluav Taws Xob Zeb>: Tsawg-ceev Thee Zeb

Cov neeg sawv cev raug ntawm cov pob ceev tsis muaj hluav taws xob yog pob zeb. Lub hauv paus ntsiab lus ua haujlwm yog: lub zog siab lub cev muaj zog los ntawm lub gearbox kom tsav qhov kev sib hloov hnyav thiab tom qab ntawd poob qis ntawm cov steel pob ntawm cov thee thiab nruab nrab ntawm Cov pob hlau, nruab nrab ntawm cov hlau pob thiab tus saib xyuas phaj, cov thee av. Qhov dhau ntawm-coarse unqualified thee yog sib cais thaum nws ntws los ntawm cov coarse hmoov separator nyob sab nraum qab ntawm lub phaj muag los ntawm cov raj xa rov qab rau kev sib tsoo. Ntxiv nrog rau kev thauj cov hmoov av, cua kub kuj ua lub luag haujlwm ntawm kom qhuav thee. Yog li ntawd, huab cua kub kuj tseem hu ua desiccant hauv cov hmoov txheej txheem. Cov khoom muaj cov yam ntxwv ntawm kev ua haujlwm ntev ntev, kev ua haujlwm yooj yim, txuag tau cov khoom loj, txuag ntau cov kev sib tsoo thee thiab lwm yam. Nws yog tsuas yog siv rau kev nyuaj thiab nruab nrab-hardness thee, tshwj xeeb tshaj yog rau cov thee nrog cov ntsiab lus volatile thiab muaj zog abrasive tej cuab yeej. Txawm li cas los xij, qhov kev siv pob hluav taws xob qis no yog bulky, muaj cov hlau loj, muaj ntau qhov av, thiab muaj qhov kev nqis peev ntau. Yog li pob zeb zeb yog haum rau tag nrho cov haujlwm ua haujlwm.

Kev Siv Hluav Taws Xob Ntau Hom 2:MUAB YEEJ CEEV CI NTHAV 

Qhov nruab nrab ceev thee zeb yog tseem hu ua cov zeb ntsug, uas yog tus cwj pwm los ntawm cov kev sib tsoo sib xyaw ntawm ob pawg ntawm cov lus tsa suab sib tsoo ntawm lub cev sib tsoo. Lub thee yog nyem thiab hauv av ntawm cov chaw ntawm ob lub cev sib tsoo thiab yog crushed. Nyob rau tib lub sijhawm, huab cua kub kub los ntawm cov thee thiab xa cov pulverized thee mus rau tus separator nyob rau sab qaum teb. Tom qab sib cais, cov mem tes ntawm qee qhov loj me me tau tawm ntawm cov zeb nrog cov cua ntws tawm, thiab cov roj ntsha pulverized txuas rov qab mus rau qhov sib tsoo ntawm thaj chaw sib tsoo. Qhov nruab nrab nrawm zeb zeb zeb muaj qhov zoo ntawm cov khoom siv cov khoom siv cog, kev taug ko taw me, muaj zog ntawm cov pob zeb), lub suab tsis muaj zog, lub teeb thiab kev tswj hwm kev tswj hwm. Tab sis nws tsis haum rau kev sib tsoo nyuaj rau thee.

Kev Xaiv Hluav Taws Xob Zeb 3: Kev Loj Ceev Thev Zeb

Qhov kev ceev ntawm cov thee-ceev cov zeb siab yog 500 ~ (min, uas yog feem ntau muaj kev sib tsoo rotor thiab sib tsoo lub plhaub. Cov kiv cua nquag sib tsoo thiab rauj sib tsoo thiab yog li ntawd. Hauv cov zeb, cov thee yog tsoo los ntawm kev sib tsoo ntawm qhov kev sib tsoo nrawm thiab lub plhaub sib tsoo thiab kev sib tsoo ntawm cov thee. Cov khoom zeb loj thiab pulverized cov thee separator formature, kev lag luam yog qhov muaj rau cov ntsiab lus siab thiab cov ntsiab lus siab, yooj yim rau grind bituminous thee. Txawm li cas los xij, vim hais tias cov kev cuam tshuam ntawm yaig thiab hnav los ntawm cov huab cua ntws, nws cov kev pab cuam lub neej yog feem ntau yuav tsum tsis txhob siab dhau, uas feem ntau siv rau Direly Blown boilers nyob rau hauv cov fais fab nroj tsuag, thiab yuav tsum tsis txhob siv rau kev txhaj tshuaj tiv thaiv cua.

Qhov saum toj no peb hom kev sib tsoo cov coal sib tsoo khoom muaj qhov zoo thiab qhov tsis zoo, hauv kev xaiv cov khoom siv thee sib tsoo, nws yog ib qho tsim nyog los xav txog cov kev xaiv ntawm pulverizing. Cov hmoov txheej txheem tuaj yeem faib ua ob pawg: kev ntaus ntawv ncaj qha thiab cov khoom sib tshooj nruab nrab (xa mus rau hom khoom cia). Nyob rau hauv ncaj qha lub tshuab pulverization Nyob rau hauv lub ntsuas phoo tso tawm, lub sam thiaj khaws cia rau hauv cov roj ntsha tau xa tawm los ntawm cov pulverized thee rau lub cub tawg rau kev ua haujlwm los ntawm pulverizer. Cov Tshuab Pulverizing txawv yog qhov tsim nyog rau ntau hom thee thiab thee sib tsoo cov khoom siv. Raws li cov mem tes purverization, peb suav cov hauv qab no rau kev xaiv thee:

(1) steel pob zeb hauv nruab nrab cia rau hauv hom huab cua huab cua hmoov (VSR <9%) thiab hnav hauv qhov muaj zog saum toj no cov thee.

(2) Pob zeb nruab nrab cia thiab tso cov roj ua kom zoo nkauj: feem ntau yog siv rau cov raj yas nrog cov hluav taws xob muaj zog (var-19%) basuminous thee.

(3) Ob-nyob rau hauv ob-out steel pob zeb ncaj tawg (vs.7-27% ~ 40%) batuminous thee.

(4) Nruab Nrab-Ceev Thiaj Thiaj Thiaj Thiaj Hluav Taws Xob Hluav Taws Xob: VANR-27%), Has noo noo Mp Khay tsis tseeb hauv qab no muaj zog, thee kev ua haujlwm yog cov nplaim taws, thiab pulverized cov thee blearle ua tau raws li cov tseev kom muaj ntawm cov zeb zeb.

(5) kiv cua zeb ncaj
