Mu gikorwa cyo gukora electrode za grafiti, ibibazo by'ikoreshwa ry'ingufu bishobora gukemurwa hakoreshejwe ingamba zirambuye, zirimo kunoza inzira z'imikorere, kongera ikoreshwa ry'ingufu, kongera imicungire y'ibikoresho, no gukoresha ikoranabuhanga rizigama ingufu. Ibisubizo byihariye ni ibi bikurikira:
I. Kunoza uburyo bwo gukaranga no guteka ibikoresho fatizo
Gutunganya ibikoresho mbere yo kuvura
Mu gihe cyo gukaraba, kugenzura ubushyuhe (1.250-1.350°C) n'igihe bimara bigabanya ubushyuhe busigaye, bikongera ubushyuhe bw'ibikoresho fatizo, kandi bigabanya ingufu zikoreshwa mu guteka nyuma. Urugero, gusimbuza amatanura asanzwe n'amatanura azunguruka cyangwa amatanura akoresha amashanyarazi bishobora kongera ubushobozi bw'ubushyuhe ku kigero cya 10%-15%.
Mu guteka, guteka ubwa kabiri cyangwa guteka inshuro nyinshi (urugero, guteka inshuro eshatu n'ibindi bine) byuzuza imyenge, bigabanya imyenge y'ibicuruzwa byarangiye, kandi byongera ubucucike bw'ibicuruzwa n'imbaraga za mekanike, bityo bigabanura ikoreshwa ry'ingufu z'ibicuruzwa.
Kunoza Uburyo bwo Gutera Inda
Mu cyiciro cyo gutera, kunoza umuvuduko w’igipimo cya asphalt (1.2-1.5 MPa) n’ubushyuhe (180-200°C) byongera igipimo cyo kongera ibiro mu gutera (≥14% ku gutera bwa mbere na ≥9% ku gutera kwa kabiri), bigabanya umubare w’ibiryo bisubirwamo kandi bikagabanya mu buryo butaziguye ikoreshwa ry’ingufu.
II. Kuvugurura ikoranabuhanga ryo kuvura Graphitization
Gutunganya ubushyuhe mu bushyuhe bwinshi
Mu gihe cyo gushushanya, gusimbuza amatanura asanzwe ya Acheson n'amatanura ahujwe n'ubushyuhe bw'imbere (LWG) bigabanya igihe cyo gukoresha ingufu (amasaha 9-15 ku matanura ya LWG ugereranyije n'amasaha 50-80 ku matanura ya Acheson) kandi bigabanya ikoreshwa ry'amashanyarazi ho 30%-50%.
Gugenzura neza ubushyuhe bwa grafitisation (2,300-3,000°C) birinda gutakaza ingufu gushyuha cyane mu gihe bigenzura ko imiterere ya karuboni ihinduka kristu za grafiti zifite imiterere itatu, bikongera imikorere y'amashanyarazi.
Gusubiza no gukoresha ubushyuhe bw'imyanda
Mu gihe cyo gukonjesha amatanura ya grafitis, ubushyuhe bw'imyanda buragaruzwa kugira ngo bushyushye mbere y'uko ibikoresho fatizo bitangira gushyuha cyangwa amazi ashyushye bitangwa, bigabanyije ingufu zikoreshwa. Urugero, hari ikigo kimwe cyazigamye metero kibe zirenga 500.000 za gaze karemano buri mwaka binyuze muri sisitemu yo kugarura ubushyuhe bw'imyanda.
III. Gushimangira ibikoresho by'umusaruro n'imicungire y'ingufu
Kongera Ikoreshwa ry'Ingufu mu Bikoresho
Guhitamo ibikoresho byo gusohora ibikoresho bigezweho, ibikoresho byo gusohora ibikoresho ku mpande, n'ibindi bikoresho byo gukora bigabanya igihombo cya mekanike; gukoresha ikoranabuhanga ryo gutwara ibintu mu buryo buhindagurika kugira ngo bigenzure umuvuduko wa moteri uhuye n'imizigo y'umusaruro kandi bigabanya ikoreshwa ry'ingufu zidakora.
Gufata neza ibikoresho by'ingenzi, nk'amatanura yo guteka no gushushanya, bituma umwuka utagira ubushyuhe kandi bigabanya ubushyuhe. Urugero, kuvugurura urwego rwo gukingira amatanura bishobora kugabanya ikoreshwa ry'ingufu z'ifuru imwe ku kigero cya 8%-12%.
Gukurikirana no kunoza ingufu
Gukoresha Sisitemu yo Gucunga Ingufu (EMS) bituma habaho gukurikirana mu buryo butunguranye ikoreshwa ry'amashanyarazi, gazi, n'ubushyuhe mu bikorwa bitandukanye, binoza gahunda z'umusaruro binyuze mu gusesengura amakuru. Urugero, guhindura uburyo bwo gushyiramo ibikoresho mu itanura ry'umuriro hashingiwe ku busabe bw'ibicuruzwa birinda "ubunini bukabije".
Gushyira mu bikorwa ingamba zo kugena ibiciro by'amashanyarazi mu kibaya cy'umuvuduko w'imvura (peak-valley) biteganya inzira zikoresha ingufu nyinshi (urugero, graphitization) mu bihe bitari iby'umuvuduko w'imvura kugira ngo bigabanye ikiguzi cy'amashanyarazi.
IV. Guteza imbere ikoranabuhanga rizigama ingufu n'ingufu zisukuye
Ikoreshwa ry'ikoranabuhanga ryo gukora ubushyuhe buke
Gusimbuza ikoranabuhanga risanzwe rikoresha umuvuduko mwinshi w’amashanyarazi n’ikoranabuhanga rikoresha ubushyuhe buke cyangwa irya isostatic bigabanya ikoreshwa ry’ingufu zishyuha. Urugero, ikigo kimwe cyagabanyije ikoreshwa ry’ingufu kuri toni imwe ya electrode ikora ku kigero cya 20% binyuze mu buryo bwo gukora bukoresha ubushyuhe buke.
Gusimbuza Ingufu Zisukuye
Gushyira gaze karemano n'ibikomoka kuri biomass buhoro buhoro aho gukoresha amakara mu gutunganya calcium no guteka bigabanya imyuka ihumanya ikirere n'ikiguzi cy'ingufu. Hari ibigo byageze ku kigero cya 60% by'ikoreshwa rya gaze karemano, bigabanya imyuka ihumanya ikirere ya CO₂ ku mwaka ho toni zirenga 10.000.
Gutanga Ingufu zishyushya imyanda no kugura amashanyarazi arengera ibidukikije
Gukoresha ubushyuhe bw'imyanda buva mu itanura rya grafitis mu gutanga amashanyarazi bihaza ibyifuzo by'amashanyarazi akomoka ku bimera; kugura amashanyarazi akomoka ku bimera (urugero: umuyaga cyangwa ingufu z'izuba) bigabanya kwishingikiriza ku bikomoka kuri peteroli kandi bigatuma habaho umusaruro muto wa karuboni.
V. Gushyira mu bikorwa imicungire yuzuye yo kuzigama ingufu
Kunoza gahunda y'umusaruro
Guhuza ibikorwa bisa (urugero, guteranya ibikoresho mu buryo buhuriweho no guteka) bigabanya imikorere y’ibikoresho kandi bigagabanya ikoreshwa ry’ingufu zitaratangira gukoreshwa. Urugero, ikigo kimwe cyazigamye arenga miliyoni 2 z’amashanyarazi buri mwaka binyuze mu kunoza gahunda yo gukora.
Amahugurwa yo Kuzigama Ingufu z'Abakozi
Gutanga amahugurwa yo kuzigama ingufu buri gihe byongera ubumenyi bw'abakozi. Urugero, gushyiraho uburyo bwo gutangiza/gufunga ibikoresho no kunoza inzira zo gukoresha ibikoresho bishobora kugabanya ikoreshwa ry'ingufu ku kigero cya 5%-8%.
Ingero z'imanza
- Ikigo Kinini cya Graphite Electrode: Mu kuvugurura amatanura ya LWG graphitization, gushyiraho sisitemu ya EMS, no gusimbuza amakara gazi karemano, ikigo cyagabanyije ikoreshwa ry’ingufu ku kigero cya 35%, cyagabanyije imyuka ihumanya ikirere ku kigero cya 40%, kandi cyazigamye amafaranga arenga miliyoni 7 z’amadolari ku mwaka.
- Uburyo bwo Kugereranya Inganda: Hari ibigo byageze ku musaruro wa "karuboni hafi ya zero" binyuze mu kugarura ubushyuhe bw'imyanda no kugura amashanyarazi ahumanya ikirere, bihuza n'uburyo isi yose ikoresha karuboni mu kugabanya karuboni no kongera ubushobozi bwo guhangana ku isoko.
