Silicon carbide ceramicsGukora uruhare runini mubikorwa byo gutanura inganda mumirenge myinshi. Porogaramu y'ibanze ni silicon carbide burner nozzles, ikoreshwa cyane muri sisitemu yo gutwika ubushyuhe bwo hejuru bwo gutunganya ibyuma, gukora ibirahuri, no kurasa ceramic bitewe nuburyo bwimiterere yabyo mubushuhe bukabije. Ubundi buryo bw'ingenzi bukoreshwa ni silikoni ya karibide, ikora nk'inkunga no gutanga ibice mu itanura rihoraho, cyane cyane mu gucumura ibumba ryakozwe neza, ibikoresho bya elegitoroniki, hamwe n'ikirahure cyuzuye. Byongeye kandi, ubukorikori bwa SiC bukoreshwa nkibigize imiterere nkibiti, gariyamoshi, hamwe nugushiraho mu ziko, aho bihanganira kumara igihe kinini bahura nikirere gikaze hamwe nihungabana ryimashini. Kwishyira hamwe kwimyanya yubushyuhe bwa sisitemu yo kugarura imyanda iragaragaza byinshi muburyo bwo gucunga amashyanyarazi. Izi porogaramu zirashimangira silicon karbide ihuza n'imikorere itandukanye ikenewe muburyo bwa tekinoroji yo gushyushya inganda.
Ibyingenzi byingenzi bikoreshwa mu nganda zirimo:
1.Silicon carbide burner nozzles
Ibyiza bya tekiniki
1. Ihinduka ridasanzwe ryubushyuhe
- Ingingo yo gushonga: 2,730 ° C (ikomeza ultra-high-temperature ibidukikije)
- Kurwanya Oxidation kugera kuri 1,600 ° C mu kirere (birinda kwangirika kwikirere cya okiside)
2. Amashanyarazi meza cyane
- 150 W / (m · K) ubushyuhe bwumuriro mubushyuhe bwicyumba (butuma ubushyuhe bwihuta no gukwirakwiza ubushyuhe bumwe)
- Kugabanya gukoresha ingufu 20-30% ugereranije nibikoresho gakondo bivunika.
3. Kurwanya Ubushuhe butagereranywa
- Ihangane ihindagurika ryubushyuhe bwihuse burenga 500 ° C / amasegonda (nibyiza byo gushyushya cycle / gukonjesha).
- Igumana ubunyangamugayo bwubatswe munsi yubushyuhe bwumuriro (birinda gucika no guhindura).
4. Imbaraga Zikomeye Zikomeye Mubushyuhe bwo hejuru
- Igumana 90% byimbaraga zubushyuhe bwicyumba kuri 1,400 ° C (ingenzi kubintu bitwara imitwaro).
- Mohs ubukana bwa 9.5 (irwanya kwambara kubikoresho byangiza mu itanura).
| Umutungo | Silicon Carbide (SiC) | Alumina (Al₂O₃) | Ibyuma bivunagura (urugero, Ni-ibivanze) | Inganda gakondo (urugero, firebrick) |
| Icyiza. Ubushyuhe | Kugera kuri 1600 ° C + | 1500 ° C. | 1200 ° C (yoroshye hejuru) | 1400–1600 ° C (biratandukanye) |
| Amashanyarazi | Hejuru (120–200 W / m · K) | Hasi (~ 30 W / m · K) | Guciriritse (~ 15–50 W / m · K) | Hasi cyane (<2 W / m · K) |
| Kurwanya Ubushyuhe | Cyiza | Abakene Kugereranya | Guciriritse (ductility ifasha) | Abakene (ibice munsi yihuta ΔT) |
| Imbaraga za mashini | Igumana imbaraga ku bushyuhe bwinshi | Impamyabumenyi iri hejuru ya 1200 ° C. | Intege nke ku bushyuhe bwinshi | Hasi (yoroheje, yoroheje) |
| Kurwanya ruswa | Irwanya acide, alkalis, ibyuma bishongeshejwe / slag | Guciriritse (yibasiwe na acide / base) | Gukunda okiside / sulfidation kuri temps nyinshi | Gutesha agaciro ikirere cyangirika |
| Ubuzima | Murebure (kwambara / okiside-irwanya) | Guciriritse (gucamo munsi yumukino wamagare) | Mugufi (oxyde / creeps) | Mugufi (gutemba, isuri) |
| Ingufu | Hejuru (ubushyuhe bwihuse) | Hasi (ubushyuhe buke bwumuriro) | Ugereranije (uyobora ariko uhindura) | Hasi cyane (insulative) |
Urubanza
Uruganda rukomeye rutunganya ibyuma bya metallurgiki rwageze ku iterambere ryibikorwa nyuma yo kwinjiza ubukorikori bwa silicon karbide (SiC) muri sisitemu yubushyuhe bwo hejuru. Mugusimbuza ibisanzwe bya alumina hamwesilicon carbide burner nozzles, ikigo cyatangaje:
✅ 40% yo hasi yumwaka wo kubungabunga bitewe no kugabanuka kw ibice muri 1500 ° C + ibidukikije.
Increase Kwiyongera 20% mugihe cyo gukora, biterwa na SiC yo kurwanya ubushyuhe bwumuriro no kwangirika bivuye kumashanyarazi.
Guhuza na ISO 50001 ibipimo ngenderwaho byo gucunga ingufu, gukoresha ingufu za SiC nyinshi kugirango zongere ingufu za peteroli 15-20%.
