Nyob rau hauv cov txheej txheem complex ntawm thee-fired thermal fais fab nroj tsuag, pulverized thee xa cov kav dej dais lub luag haujlwm tseem ceeb ntawm kev thauj cov roj pulverized kom nyab xeeb thiab ua tau zoo rau hauv qhov cub. Qhov kub nyob rau hauv cov kav dej no yog qhov tseem ceeb uas cuam tshuam ncaj qha rau kev nyab xeeb thiab kev lag luam ntawm lub boiler. Nws yuav tsum tsis txhob siab dhau, tsam nws ua rau tawg; los yog tsawg dhau, vim hais tias yuav cuam tshuam combustion efficiency los yog ua rau cov yeeb nkab blockages.
1. Qhov kub thiab txias Profile ntawm cov yeeb nkab xa khoom: Ib qho Dynamic Range
Qhov kub hauv lub pulverized thee xa cov yeeb nkab tsis yog tus nqi ruaj khov tab sis muaj ntau yam sib txawv nrog cov kev ua haujlwm. Raws li kev tshuaj xyuas dav dav ntawm cov ntaub ntawv muaj, qhov kev ua haujlwm kub ua haujlwm feem ntau poob ntawm 100℃thiab 270 degree.
Kev khiav hauj lwm kub: Raws li cov qauv tsim, cov yeeb nkab yuav tsum tiv taus qhov kub ntawm 100-200 degree. Hauv kev ua haujlwm tiag tiag, cov tshuab siv cov cua kub xa tawm tuaj yeem pom qhov kub siab dua -piv txwv li, hauv cov nroj tsuag hlawv anthracite, qhov nruab nrab kub tuaj yeem ncav cuag 250-270 degree.
Tsim kev nyab xeeb pib: Txhawm rau tiv thaiv kev tawg ntxov ntxov ntawm pulverized thee nyob rau hauv cov yeeb nkab, cov cai tseem ceeb tau teev tseg tias qhov kub ntawm huab cua sib tov ua ntej lub burner yuav tsum tsis pub tshaj 160 degree. Yog li ntawd, cov cuab yeej tsim qhov kub thiab txias feem ntau suav rau cov xwm txheej hnyav dua; ntau cov kav dej xa khoom thiab lawv cov khoom yog tsim los rau 350℃lossis txawm 450 degree.
2. Kev cuam tshuam cuam tshuam tom qab qhov kub thiab txias: Kev sib cuam tshuam ntawm ntau qhov sib txawv
Qhov kub ntawm cov yeeb nkab xa khoom yog txiav txim siab los ntawm ntau qhov sib cuam tshuam, tsis yog los ntawm ib leeg ib leeg.
Conveying method: Qhov no yog qhov tseem ceeb tshaj plaws. Cov cua kub cua tshuab siv kwv yees li 300℃cua kub ua qhov nruab nrab ntawm kev thauj mus los, ua rau cov yeeb nkab kub dua. Nyob rau hauv sib piv, qhuav-flue-gas conveying los yog ncaj qha hluav taws xob pulverizing tshuab ua hauj lwm nyob rau hauv kuj qis kub.
Cov khoom siv thee: Cov coals sib txawv muaj qhov sib txawv ntawm cov teeb meem tsis zoo thiab cov dej noo, uas ua rau kom qhuav thiab thauj cov kub sib txawv. Coals nrog cov teeb meem tsis zoo no feem ntau ua rau tawg thiab yog li thov kev tswj hwm nruj dua li qhov ntsuas kub siab.
Qhov hluav taws xob kub ntawm lub pulverizing system: Lub pulverized thee tawm hauv lub zeb ntawm qhov kub thiab txias -qhov no ua haujlwm li "pib taw tes" rau cov yeeb nkab kub. Qhov hluav taws xob qhov hluav taws xob no cuam tshuam los ntawm cov hom thee, hom zeb, thiab lwm yam, thiab feem ntau yog li ntawm 65℃txog 100 degree.
Ambient tej yam kev mob thiab cov yeeb nkab thaum tshav kub kub poob: Thaum lub sij hawm thauj, cov yeeb nkab exchanges tshav kub nrog rau ib puag ncig, ua rau ib tug maj mam kub poob raws txoj kev. Cov kev tshawb fawb qhia tau hais tias thaum qhov kub ntawm qhov sib txawv ntawm cov hmoov thiab qhov chaw ib puag ncig siab tshaj 100 degree, 100-meter yeeb nkab yuav muaj qhov kub thiab txias ntawm 10-15 degrees.
3. Vim li cas Kev Tswj Xyuas Qhov Tseem Ceeb: Peb Lub Hom Phiaj Tseem Ceeb
Kev tswj xyuas qhov kub thiab txias ntawm pulverized thee xa cov kav dej yog ib qho ntawm cov haujlwm tseem ceeb hauv kev tswj fais fab nroj tsuag, thiab nws qhov tseem ceeb yog peb npaug.
Ua kom muaj kev nyab xeeb thiab tiv thaiv kev tawg: Qhov no yog qhov laj thawj tseem ceeb thiab tseem ceeb tshaj plaws. Qhov kub ntau dhau tuaj yeem ua rau cov roj pulverized ignite spontaneously los yog txawm tawg thaum thauj, ua rau muaj xwm txheej loj. Yog li ntawd, qhov kub ntawm cov huab cua-roj sib tov yuav tsum nruj me ntsis tswj hauv qab qhov kev nyab xeeb txwv (piv txwv li, 160℃).
Xyuas kom txaus thiab tiv thaiv cov yeeb nkab thaiv: Yog tias qhov kub thiab txias qis dhau, cov dej noo hauv cov thee yuav tsis tag nrho evaporate, ua rau cov thee lo rau hauv cov yeeb nkab phab ntsa thiab tsim cov blockages. Tuav qhov ntsuas kub kom txaus yog qhov tseem ceeb rau kev ntws zoo ntawm cov roj pulverized.
Txhim kho efficiency thiab optimizing combustion: ib tug tsim nyog tus me nyuam kub pab lub pulverized thee ignite sai sai thaum nkag mus rau hauv lub cub tawg, li no pab kom combustion efficiency thiab tag nrho boiler thermal efficiency. Tsis tas li ntawd, qhov kub thiab txias yog qhov tseem ceeb rau kev kho cov cua combustion.
4. Yuav ntsuas qhov kub li cas kom raug: Los ntawm kev sib cuag mus rau qhov chaw deb
Txhawm rau saib xyuas cov yeeb nkab kub hauv lub sijhawm, cov chaw tsim hluav taws xob siv ntau yam kev ntsuas.
Kev ntsuas kev sib cuag: Txoj kev siv ntau tshaj plaws yog ntxig lub thermocouple nrog cov ntaub thaiv npog ncaj qha rau hauv cov yeeb nkab. Txawm li cas los xij, txoj hauv kev no muaj qhov tsis zoo, suav nrog kev cuam tshuam ntawm cov dej ntws, kev cuam tshuam rau kev yaig los ntawm cov khoom siv hluav taws xob, thiab qhov tseeb tias qhov kev nyeem ntawv tsuas yog sawv cev rau qhov kub thiab txias.
Advanced non-contact / indirect ntsuas: Kom kov yeej cov kev txwv no, kev lag luam tau tsim txoj kev tshiab. Piv txwv li, ntsuas cov phab ntsa sab nrauv ntawm cov yeeb nkab thiab tom qab ntawd xam qhov nruab nrab sab hauv nruab nrab kub siv cov qauv lej. Tsis tas li ntawd, qee lub tshuab sau cov ntaub ntawv kub los ntawm ob qho tib si sab sauv thiab sab qis ntawm cov yeeb nkab phab ntsa kom txiav txim siab seb puas muaj cov pob zeb tso rau hauv.
5. Cov ntsiab lus
Qhov kub ntawm pulverized thee xa cov yeeb nkab yog qhov tseem ceeb tsis zoo uas cuam tshuam rau tag nrho cov pulverizing system nyob rau hauv lub thermal fais fab nroj tsuag. Nws tsis yog tus lej sib cais tab sis qhov tshwm sim ntawm kev sib cuam tshuam ntawm txoj kev xa khoom, thee zog, pulverizer kev ua haujlwm, ambient ib puag ncig, thiab lwm yam. Kev saib xyuas kom raug thiab kev tswj xyuas qhov kub thiab txias yog qhov ua kom sib npaug ntawm peb lub hom phiaj tseem ceeb ntawm kev nyab xeeb, kev ua haujlwm, thiab kev lag luam- ua haujlwm tiag tiag li "thermometer" rau kev ua haujlwm nyab xeeb.
Yog tias koj muaj qhov tshwj xeeb tseem ceeb dua -xws li qhov kub ntawm qhov chaw tshwj xeeb (xws li lub qhov hluav taws xob zeb lossis lub qhov hluav taws xob hluav taws xob) lossis ib qho teeb meem ntsig txog qhov kub thiab txias uas koj tab tom ntsib - thov koj xav tias dawb muab cov ntsiab lus ntxiv, thiab kuv yuav zoo siab los muab cov ntsiab lus pom ntxiv.
