Silicon karbide (SiC) ceramic nozzlesbabaye ibice byingenzi mubikorwa bitandukanye byinganda, cyane cyane mubijyanye na gazi ya flulfurizasi (FGD). Utwo dusimba twateguwe neza kugirango duhangane n’ibihe bikabije kandi bikwiranye n’ibidukikije aho ubushyuhe bwinshi n’ibintu byangirika byiganje. Imiterere yihariye yabo, harimo imbaraga nyinshi, gukomera no kwambara no kurwanya ruswa, bituma bahitamo neza kunoza imikorere yinganda zamashanyarazi na turbine.
Silicon carbide ceramic nozzles igira uruhare runini mugikorwa cya desulfurizasi mumashanyarazi. Igikorwa nyamukuru cyi majwi ni uguteza imbere gutera imiti imwe ya desulfurizasi, ifite akamaro kanini mu kugabanya imyuka ya dioxyde de sulfure (SO2) mu myuka ya flue. Ubushyuhe bwo hejuru bwa karibide ya silicon ituma izo nogisi zikora neza mubihe bibi bisanzwe biranga amashanyarazi. Mugukwirakwiza ikwirakwizwa ryumukozi wa desulfurizasiya, utwo dusimba tunoza cyane imikorere ya desulfurizasi muri rusange, bityo bikagabanya cyane imyuka ihumanya ikirere.
Kuramba kwa silicon karbide nozzles nibindi byiza byingenzi. Mubidukikije aho ibikoresho gakondo bishobora kwangirika vuba kubera kwangirika cyangwa kwambara, karbide ya silicon iragaragara kubera igihe kirekire cyakazi. Uku kuramba bisobanura amafaranga make yo kubungabunga hamwe nigihe gito cyo gukora kumashanyarazi kuko abashoramari barashobora kwishingikiriza kuri ziriya majwi kugirango bakomeze gukora mugihe kirekire. Ku mashanyarazi aharanira kubahiriza amategeko akomeye y’ibidukikije, ubushobozi bwo gukomeza ubusugire bw’ibikorwa mu bihe bigoye ni ngombwa.
Byongeye kandi, ikoreshwa rya silicon karbide nozzles irenze ibirenze gaze ya gaz. Muri gaz turbine, izo nozzles zifasha kweza imyuka mbere yuko yinjira muri turbine. Ubukomezi bwinshi nimbaraga za karubide ya silicon ituma igenzura neza imigendekere ya gaze, ikemeza umwanda muke. Ubu buryo bwo kweza ni ngombwa mu mikorere myiza ya gaz turbine, kuko ifasha gukumira ibyangiritse no gukomeza urwego rwiza. Ukoresheje silicon carbide nozzles, abashoramari barashobora kuzamura ubwizerwe nubushobozi bwa sisitemu ya turbine.
Ubwinshi bwa silicon carbide ceramic nozzles bugaragarira kandi mubushobozi bwabo bwo gukora mubikorwa bitandukanye byinganda. Usibye kubyaza ingufu amashanyarazi na gaz turbine, izo nozzles zishobora no gukoreshwa mugutunganya imiti, gucunga imyanda nizindi nzego zisaba ibikoresho bikora neza. Imiti yabo irwanya imiti ituma bakoreshwa mubidukikije aho ibintu byangirika biboneka, bakemeza ko bishobora kwihanganira ubukana bwibikorwa bitandukanye byinganda.
Usibye imiterere yubukanishi nubumashini, silikoni karbide nozzles nayo igira uruhare mukubungabunga ibidukikije. Mu kunoza imikorere ya desulfurizasi no kugabanya ibyuka bihumanya ikirere, izo nogisi zigira uruhare runini mu gufasha inganda kubahiriza amabwiriza y’ibidukikije. Mu gihe isi yose imenyekanisha ubuziranenge bw’ikirere no kurwanya umwanda bikomeje kwiyongera, biteganijwe ko hakenerwa ibisubizo bifatika nka silicon carbide ceramic nozzles. Ubushobozi bwabo bwo guteza imbere ibikorwa bisukuye bihuza nintego nini yo kugabanya ingaruka zibidukikije mubikorwa byinganda.
Muri make, silikoni karbide ceramic nozzles ningirakamaro mubikorwa byinganda bigezweho, cyane cyane mubikorwa bya gaze ya gaz no gukora gaz turbine. Imbaraga zidasanzwe zidasanzwe, gukomera, kurwanya ruswa no kurwanya kwambara bituma biba byiza mugutezimbere amashanyarazi no kugabanya ibyuka bihumanya. Mugihe inganda zikomeje gushyira imbere kuramba no kubahiriza amahame y’ibidukikije, nta gushidikanya uruhare rwa silicon karbide nozzles ruzagaragara cyane, bizatanga inzira y’inganda zisukuye kandi zinoze.
