Biochar

Hauv cov thee- cov chaw hluav taws xob raug rho tawm haujlwm, cashew nut plhaub (CNS) biochar yog tag nrho nrog cov pulverized thee boilers uas twb muaj lawm thiab circulating fluidized txaj (CFB) boilers, ua kom co- tua lossis mob siab rau firing nrog theetsis loj -scale retrofitting ntawm cov units uas twb muaj lawm. Nws ua haujlwm raws li tus nqi qis - txoj hauv kev rau cov chaw tsim hluav taws xob kom ua tiav cov luag haujlwm txuas ntxiv hluav taws xob thiab cov hom phiaj txo cov pa roj carbon monoxide.

• Cov khoom siv roj zoo sib xws nrog cov thee:
  Cov txiv ntoo txiv ntoo plhaub (CNS) biochar xa tawm aCov nqi hluav taws xob siab dua (HHV)uas yog piv rau bituminous thee thiab deb outperforms ntau biomass fuels. Nws nta combustion stability zoo ib yam nrog thee, kom ruaj khov kev txhawb nqa rau chav tsev fais fab load. Nws cov khoom ua raws li cov kev caiEU tus qauvrau cov khoom siv biofuels, tsim nyog rau kev siv ncaj qha raws li kev lag luam roj.Ntuj lubricity: Txhim kho roj lubrication, tiv thaiv cov twj tso kua mis thiab cov twj tso kua mis.
• Flexible Co-firing Compatibility:
  cashew nut plhaub (CNS) biochar tuaj yeem muab sib xyaw nrog cov thee, ntoo chips thiab lwm yam khoom siv roj hauv kev sib piv rau co-combustion. Tam sim no, cov ntawv thov kev lag luam tau ua tiav qhov sib xyaw ruaj khov ntawm 10%-30%, thiab cov phiaj xwm kev sim tau txheeb xyuas qhov ua tau mus txog 50% kev sib xyaw, yam tsis muaj kev cuam tshuam rau boiler combustion efficiency lossis tso zis. Ntau lub chaw tsim hluav taws xob biomass thiab cov thee retrofitted- cov chaw tsim hluav taws xob tawm txawv teb chaws tau ua tiav cov roj no, ua pov thawj nws txoj haujlwm ruaj khov mus ntev.
• Zoo kawg nkaus Environmental & Cost Advantages:
  cashew nut plhaub (CNS) biochar muaj ultra-tsis muaj impurities: qis dua li cov pa roj carbon monoxide. Qhov no tuaj yeem txo cov pa phem xws li SO₂, NOₓ thiab HCl, ua kom lub zog ua haujlwm ntawm desulfurization thiab denitrification cov cuab yeej thiab txiav cov nqi ua haujlwm ib puag ncig.

Lub caij no, raws li cov roj txuas ntxiv tau muab los ntawm kev ua liaj ua teb pov tseg, nws cov pa roj carbon emission haum rau lub voj voog "carbon neutral". Txhua tuj ntawm cashew txiv ntoo plhaub (CNS) biochar siv tau tuaj yeem txo kwv yees li 2.6 tons ntawm fossil CO₂ emissions, pab cov nroj tsuag hluav taws xob ua tau raws li cov hom phiaj ntawm cov pa roj carbon quota thiab zam cov nqi them nqi carbon.

Hauv cov hlau thiab tsis yog -ferrous smelting industries, cashew txiv ntoo plhaub (CNS) biochar tuaj yeem hloov cov coke metallurgical coke thiab pulverized thee ib txhij, ua ob qho tib si roj thiab reductant rau tag nrho - txheej txheem txheej txheem suav nrog coking, sintering, blast furnace thiab hluav taws xob arc mel rau kev lag luam rau kev ua haujlwm, decarbonization.

Coke / Coal Hloov rau Steel Kev Lag Luam​

Hauv kev tsim steel, cashew txiv ntoo plhaub (CNS) biochar tuaj yeem hloov 5% -50% ntawm coke / pulverized thee, npog ntau cov txheej txheem: coking thee blending, hlau ore sintering, blast furnace txhaj thiab hluav taws xob arc rauv steelmaking:

• Nyob rau hauv cov txheej txheem blast furnace, biochar muaj qhov txo qis reactivity zoo dua li cov tsoos coke, uas tuaj yeem txo qhov blast furnace coke piv.
• Lub caij no, nws cov ultra- tsis tshua muaj leej faj thiab phosphorus impurities zam cov khoom tsis zoo uas qhia los ntawm cov thee tsoos, txhim kho cov purity ntawm steel khoom.

Clean Reductant rau Tsis yog -Ferrous Smelting​

Hauv cov uas tsis yog -ferrous hlau smelting xws li npib tsib xee thiab tooj liab, cashew nut plhaub (CNS) biochar tuaj yeem hloov cov thee ib txwm ua roj thiab reductant rau submerged arc furnaces, uas yog tshwj xeeb tshaj yog haum rau smelting refractory ores xws li lateritic nickel ore. Nrog nws cov pa roj carbon ntau ruaj khov thiab cov hmoov tshauv tsawg, nws tuaj yeem txhim kho kev ua haujlwm smelting thiab txo cov slag tso zis. Cov ntaub ntawv tshawb fawb qhia tau hais tias tom qab siv CNS biochar los hloov cov thee, tag nrho - cov pa roj carbon emissions ntawm nickel smelting yuav raug txo los ntawm ntau tshaj 25%, thaum txo cov kua qaub emissions xws li SO₂, txo qis ib puag ncig siab ntawm smelters.

Kev Ua Raws Cai & Cov Khoom Siv Carbon Tus Nqi

Rau kev xa tawm -cov tuam txhab lag luam smelting, siv cashew txiv ntoo plhaub (CNS) biochar los hloov cov thee tuaj yeem txo cov khoom lag luam zoo, pab cov lag luam tiv thaiv kev lag luam xws li EU'sCarbon Ciam Teb Kho Mechanism (CBAM). Lub caij no, nws tuaj yeem tsim cov pa roj carbon emissions txo qis, tsim cov khoom muaj nqis ntxiv rau cov lag luam.

Piv nrog rau lwm yam biomass chars, cashew nut plhaub (CNS) biochar muaj ntau qhov zoo rau kev siv hauv kev lag luam:

• Siab zog ceev: Nws cov khoom siv raw muaj lignin cov ntsiab lus siab, thiab lub zog ceev tom qab pyrolysis tau txhim kho ntau dua li cov ntoo biomass zoo tib yam.
• Ultra-Cov ntsiab lus tsis muaj impurity tsawg: Cov ntsiab lus tshauv yog qis dua li cov khoom pov tseg xws li straw thiab nplej husk, tsis txhob muaj teeb meem xws li boiler slagging thiab ntau smelting slag.
• Circular Economy Attribute: Cov khoom siv raw yog pov tseg los ntawm- cov khoom lag luam los ntawm kev ua qoob loo, uas tsis nyob hauv thaj av ua liaj ua teb lossis sib tw nrog cov qoob loo noj zaub mov, ua kom muaj txiaj ntsig zoo - siv cov khoom pov tseg ua liaj ua teb thiab ua raws li kev lag luam thoob ntiaj teb kev loj hlob.
