Kuki amatafari ya keramike adashira akwiriye gukoreshwa mu kurwanya kwangirika kw'ibikoresho by'uruganda rutanga amashanyarazi?

Mu gihe cy'imikorere y'inganda zitanga ingufu zishyuha, kwangirika kw'ibikoresho byagiye biba ikibazo cy'ingenzi kigira ingaruka ku musaruro no kongera ikiguzi cyo kubungabunga. Imashini zitwara amakara n'imiyoboro y'amakara yo mu buryo bwo gutwara amakara, hamwe n'ibikoresho bitanga amashanyarazi n'ibishyushya cyane byo muri ubwo buryo, bihura n'isuri y'igihe kirekire bitewe n'ibikoresho ndetse n'ubushyuhe bwinshi, bigatuma byangirika cyane. Mu myaka ya vuba aha, amatafari ya alumina ceramic yakoreshejwe cyane mu rwego rwo kurwanya kwangirika mu nganda zitanga ingufu bitewe n'imikorere yazo myiza, bigatuma zigaragaza ingaruka nziza zo kurwanya kwangirika no gukemura iki kibazo neza.

Ubushobozi bwiza bwo kurwanya kwangirika kw'amatafari ya alumina buturuka ku miterere yayo yihariye y'ibikoresho. Amatafari ya alumina afite ubukana bwinshi cyane, afite ubukana bwa Mohs bugera kuri 9, akaba ari ubwa kabiri nyuma ya diyama, kandi ashobora kurwanya kwangirika gukomeye kw'uduce tw'ibikoresho. Hagati aho, anafite ubukana bwiza bwo kwangirika. Ubukana bwayo bungana n'inshuro 266 z'icyuma cya manganese n'inshuro 171.5 z'icyuma cya chromium kinini, bishobora kongera igihe cyo gukoresha ibikoresho. Byongeye kandi, amatafari ya alumina afite ubukana bwiza bwo kwangirika kandi ashobora gukora neza ahantu hari ubushyuhe bwinshi bwa 1200℃, bigatuma akora neza cyane mu gukoresha ibikoresho birwanya kwangirika mu bushyuhe bwinshi mu nganda z'amashanyarazi.

Mu ikoreshwa ry’inganda z’amashanyarazi, uburyo bwo gushyiraho impapuro za alumina ceramic burahindagurika kandi buratandukanye. Ubusanzwe burimo ubwoko bwa kole, ubwoko bwa inlay n’ubwoko bwa suider. Gushyiraho kole ni ugufata neza impapuro za ceramic ku buso bw’ibikoresho binyuze mu ma kole yihariye irwanya ubushyuhe bwinshi kandi ikomeye. Ubu buryo bworoshye gukoresha kandi bukwiriye ibice bifite imiterere igoye. Gushyiraho kole bikubiyemo gutunganya imiyoboro ku buso bw’ibikoresho bihuye n’imiterere y’urupapuro rwa ceramic no gushyiramo urupapuro rwa ceramic. Ubu buryo bufite ingaruka nziza zo gufunga kandi bukwiriye ibice bishobora gukubitwa cyane. Gushyiraho kole bikubiyemo gusudira impapuro za ceramic ku buso bw’ibikoresho binyuze mu buryo bwihariye bwo gusudira. Bufite imbaraga nyinshi zo guhuza kandi bukwiriye ahantu hashaje cyane kandi hakorerwa akazi gakomeye.

Fata urugero rw'umuyoboro w'amakara w'uburyo bwo gutwara amakara bw'uruganda rw'amashanyarazi. Mbere yo gushyiraho plaque za alumina ceramic, bitewe n'uko uduce tw'amakara dukomeza kwangirika, urukuta rw'umuyoboro w'amakara rwashaje cyane, kandi rwagombaga gusimburwa buri mezi atandatu. Ibi ntibyazamuye ikiguzi cyo kubungabunga gusa ahubwo byanagize ingaruka ku musaruro usanzwe w'uruganda rw'amashanyarazi. Nyuma yo gukoresha kole yo gushyiraho plaque za alumina ceramic, imbaraga zo kwangirika kw'umuyoboro w'amakara zariyongereye cyane, igihe cyo gusimbuza cyongerewe kugeza ku myaka 3 kugeza kuri 5, bigabanya cyane igihe cyo kubungabungwa no kunoza imikorere y'umusaruro.

Gukoresha amatafari ya alumina mu bice nka economizers na superheaters bya sisitemu ya boiler nabyo byagize ingaruka nziza zo kurwanya kwangirika. Ibi bice byagiye bihura n'ubushyuhe bwinshi n'umukungugu mwinshi igihe kirekire, bigatera ibibazo bikomeye byo kwangirika no kwangirika. Mu gushyiraho amatafari ya alumina mu buryo bworoshye cyangwa busutswe, hashyirwaho urwego rukomeye rwo kurinda, rurwanya neza kwangirika no kwangirika kw'umukungugu ushyushye cyane, rugabanya igipimo cyo kwangirika kw'ibice, kandi rukongera umutekano n'umutekano w'imikorere ya boiler.

Gukoresha amatafari ya alumina mu nganda z'amashanyarazi ntibyongera gusa imikorere y'ibikoresho mu kurwanya kwangirika, ahubwo binazana inyungu nyinshi mu bukungu. Kugabanya inshuro zo kubungabunga no gusimbuza ibikoresho byagabanyije ikiguzi cyo kubisana no gutakaza igihe cyo gukora. Kongera igihe cyo gukora ibikoresho, kongera ubwizigirwa n'imikorere myiza, no gutanga icyizere gikomeye cy'umusaruro uhamye w'inganda z'amashanyarazi. Hamwe n'iterambere rihoraho ry'ikoranabuhanga, amahirwe yo gukoresha amatafari ya alumina mu nganda z'amashanyarazi azarushaho kuba manini, kandi byitezwe ko azagira uruhare runini mu nzego nyinshi, afasha inganda z'amashanyarazi kugera ku mikorere myiza, ihamye kandi ihenze.
