Oxy- thev naus laus zis hluav taws xob tsis yog ib qho txheej txheem tab sis ib qho kev siv tshuab dav dav siv los ua kom cov pa oxygen concentration hauv combustion- txhawb nqa roj. Nws lub hom phiaj yog txhawm rau txhim kho cov txheej txheem combustion, txhim kho lub zog ua haujlwm, thiab txo cov pa phem. Hauv cov ntsiab lus yooj yim, oxy- roj combustion txhais tau tias "ua kom hluav taws kub hnyiab ntau dua, huv dua, thiab ntse dua."
Hom Lub Npe ntawm Oxy- Roj combustion technologies
1. Tsob Ntoo Oxygen-Txoj kev sib xyaw kom zoo (Ntxiv cov pa me me)
-Txoj kev:Muab cov pa oxygen-ua kom muaj huab cua (piv txwv li, nce oxygen concentration ntawm 21% mus rau 28%) rau hauv cov huab cua combustion zoo tib yam.
- Cov nyhuv:Cov nplaim hluav taws kub zoo dua, txhim kho cov cua sov hloov mus,Kev txuag hluav taws xob ncaj qha (5% -15% txuag hluav taws xob), thiab nce cov khoom tsim tawm.
- Zoo tshaj rau: Industrial furnace retrofitting - feem ntau thiab kev daws teeb meem.
2. Pure Oxygen combustion (Full Oxygen Txhaj)
- Txoj kev:Siv ze li ntawm cov pa ntshiab ntshiab rau combustion thaum rov ua dua lub ntim loj ntawm cov pa pa (tsuas yog CO₂) los tswj cov nplaim taws kub.
- Cov nyhuv:Kev siv hluav taws xob siab tshaj plaws (txog 30% + roj txuag). Cov pa roj flue yog yuav luag ntshiab CO₂,ua rau nws yooj yim heev rau ntes thiab khaws cia- ib qho tseem ceeb ntawm xoom- carbon combustion thiab carbon capture, utilization, and storage (CCUS).
3. Oxygen-Txhim kho combustion (Precision Oxygen Txhaj)
- Txoj kev:Tsis txhob sib xyaw cov pa oxygen nrog cov huab cua combustion ntau, cov pa me me ntawm cov pa ntshiab huv tau raug txhaj zoo li "tua" ncaj qha rau hauv cov roj lossis cov nplaim hluav taws.
- Cov nyhuv:Ua tiav qhov ruaj khov, siab - siv hluav taws xob siv oxygen tsawg. Zoo tagnrho rau hlawvqis- qib rojlos yog daim ntawv thov yuav tsum tau cov nplaim taws zoo tswj.
4. Chemical Looping Combustion (Tom ntej no)
- Txoj kev: Tshem tawm qhov xav tau huab cua. Roj reacts indirectly nrog cov pa oxygen carrier (piv txwv li, hlau oxide hais) kom tau oxygen.
- Cov nyhuv:Inherently ua cov ntshiab CO₂ npaj rau sequestration. Txoj kev zoo tshaj plaws, tab sis tseem nyob rau theem R & D.
Daim Ntawv Thov Kev Lag Luam Tseem Ceeb ntawm Oxy- Roj Technology
Oxy- roj combustion tau txav los ntawm txoj kev xav mus rau kev lag luam kev lag luam thoob plaws ntau qhov chaw:
- Kev tsim hluav taws xob (cov chaw tsim hluav taws xob cua sov)
- Kev tsim iav
- Hlau, hlau, thiab metallurgy
- Kev tsim cov cement
- Ceramic tua hluav taws
- Kev puas tsuaj pov tseg (txhim kho kev puas tsuaj thiab kev tshem tawm)
- Lub cav thiab roj turbines (tam sim no nyob rau hauv kev sim theem)
Cov txiaj ntsig tseem ceeb thiab qhov zoo ntawm Oxygen-Txoj kev sib xyaw ua ke
✅ Txuag Zog
Ua kom thermal efficiency, txo cov roj noj los ntawm 5% mus rau 30%.
✅ Emission txo
- Direct CO₂ txo los ntawm kev siv roj tsawg
- Txo cov roj flue ntim → txo qis cov cua sov poob thiab txo qis cov cua ntsawj ntshab lub zog noj
- Tshem tawm ntawm thermal NOx tsim (vim kev tswj kub thiab txo nitrogen)
- Kev ua kom tiav ntau dua → qis CO thiab cov pa roj carbon monoxide emissions
✅ Kev tsim khoom siab dua & Zoo
Ua kom muaj zog ntau lawm (tso zis), txhim kho cov khoom zoo (xws li, iav uniformity), thiab boosts tag nrho cov txheej txheem efficiency.
✅ Txhim kho roj Flexibility
Ua kom muaj txiaj ntsig zoo ntawm kev siv qis - tus nqi calorific, siab - noo noo, lossis lwm yam roj, ua rau kev ua haujlwm hloov tau thiab ruaj khov.
