Ib lub nkoj loj ntawm Yuchai 12VCN thiab 16VCN roj teeb lub thawv hluav taws xob teeb, nrog rau tag nrho cov peev txheej ntawm 24.5 MW, tau raug xa mus rau qhov chaw nres tsheb thee-mine-gas (CMM) lub zog tsim hluav taws xob hauv Bijie, Guizhou Province, xa cov hluav taws xob huv ntawm qhov chaw los ntawm kev hloov cov roj hluav taws xob hauv hluav taws xob rau hauv hluav taws xob.
1. Project Background: Bijie, Guizhou Coal-Mine-Gas Resource
Nyob rau hauv Southwest Tuam Tshoj lub loj thee-tsim cheeb tsam, Bijie yog nplua nuj nyob rau hauv cov thee-mine gas peev txheej, uas yog muab rho tawm los ntawm underground thee seams thaum lub sij hawm mining. Yog tias tsis muaj kev siv tau zoo, cov pa roj methane-nplua nuj yuav raug tso rau hauv qhov chaw, nkim cov khoom siv hluav taws xob muaj txiaj ntsig thiab tsim cov pa hluav taws xob ntau hauv tsev cog khoom. Qhov no 24.5 MW thawv-hom roj-powered chaw nres tsheb ua raws li lub tswv yim ntawm"txhawb nqa cov pa roj los ntawm kev siv roj, thiab ua kom muaj kev nyab xeeb ntawm cov mining los ntawm cov kua dej zoo". Nws hloov cov pa roj carbon monoxide txaus ntshai rau hauv hluav taws xob tsawg-carbon, muab hluav taws xob ruaj khov rau kev ua haujlwm hauv kuv lub cev thaum pub nyiaj txaus rau hauv daim phiaj pej xeem hauv zos. Txoj haujlwm txhawb nqa kev tswj hwm kev nyab xeeb hauv zej zog, kev txuag hluav taws xob, txo qis emissions thiab cov hom phiaj hloov pauv ntsuab.
2. Qhov laj thawj rau Yuchai 12VCN & 16VCN Gas-Engine Solution
Txoj haujlwm no siv Yuchai 12-lub tog raj kheej V-hom (12VCN) thiab 16-lub tog raj kheej V-hom (16VCN) roj cav, lub hom phiaj-tsim rau qhov sib txawv-concentration thee-mine-gas ua haujlwm. Multi-unit parallel-running configuration muab tag nrho 24.5 MW tso zis tso zis. Container-skid-mounted design drastic shortens on-site building cycles, txo cov pej xeem-engineering peev, thiab muab kev tiv thaiv zoo tiv thaiv Guizhou lub high-humidity, hilly-steev chaw ua hauj lwm ib puag ncig. Cov roj siv hluav taws xob no tau tsim kho kom haum raws li qhov kev hloov pauv hauv cov pa roj methane concentration thiab muab lub zog, ua kom lub sijhawm ntev, txhim khu kev qha, ua haujlwm tsis tu ncua rau kev tsim hluav taws xob ib puag ncig.

4. Kev Ua Haujlwm Tus Nqi Tom Qab Kev Ua Haujlwm
Txij li thaum pib ua haujlwm, 24.5 MW lub thawv-hom roj hluav taws xob chaw nres tsheb tau siv tag nrho cov roj av-drained thee-mine. On-site generated fais fab mov muab qhov tseem ceeb hluav taws xob rau mine qhov cua, dej-twj thiab cov khoom siv tseem ceeb. Ntau lub zog raug xa tawm mus rau hauv cheeb tsam lub zog hluav taws xob, tsim kom muaj cov nyiaj tau los ntev ntev. Lub Yuchai 12VCN / 16VCN roj hluav taws xob chav tsev tau tswj hwm kev ua haujlwm siab, ruaj khov ua haujlwm tsis tu ncua, txiav cov pa roj carbon monoxide emissions thiab xa cov txiaj ntsig yeej-yeej suav nrog kev txhim kho mine-kev nyab xeeb, kev siv peev txheej thiab cov txiaj ntsig kev lag luam qis.
5. Cov lus nug nquag nug (FAQ)
Q: Vim li cas thiaj xaiv 12VCN thiab 16VCN roj-tso cav rau thee-mine-gas fais fab tiam?
A: Lub tshuab hluav taws xob Yuchai VCN-series tau ua kom zoo rau cov thee-mine gas, nrog rau kev hloov pauv kom muaj zog rau kev hloov pauv ntawm cov methane concentration thiab cov pa roj siab -- qhov kev sib tw tseem ceeb rau mine-gas fais fab-generation project.
Q: Dab tsi yog qhov zoo ntawm lub thawv-hom configuration rau qhov project no?
A: Kev tsim cov thawv ntim tau zoo heev txo qhov chaw teeb tsa lub sijhawm, txo cov nqi tsim kho, thiab muab kev tiv thaiv txhua huab cua tiv thaiv cov av noo, huab cua thiab roob-kev nyab xeeb corrosion hauv thaj tsam Bijie.
Q: Qhov chaw nres tsheb 24.5 MW siv nws cov hluav taws xob tsim tawm li cas?
A: Tsim lub hwj chim yog qhov tseem ceeb los muab cov khoom tseem ceeb ntawm qhov chaw mine; lub zog tshaj tawm yog pub rau hauv daim phiaj pej xeem hauv zos kom xa nyiaj txiag thiab ib puag ncig rov qab los.
