Isesengura rishya rya Nernst 1735 risesengura ni igikoresho kidasanzwe gishobora gupima ubushyuhe bwikime cya acide muri gaze ya flue ya boiler hamwe n’itanura rishyushya kumurongo mugihe nyacyo. Ubushyuhe bwikime bwa acide bupimwe nigikoresho kirashobora kugenzura neza ubushyuhe bwa gaze ya gaze ya peteroli hamwe n’itanura ryashyushya, kugabanya ibikoresho byo mu bushyuhe buke bwa sulfurike acide ya dew point ya ruswa, kunoza imikorere yumuriro, kongera umutekano wogukoresha no kongera ubuzima bwibikoresho.
Nyuma yo gukoresha isesengura ryikime cya Nernst 1735, urashobora kumenya neza agaciro kerekana ikime cya acide muri gaz ya flue ya gaz hamwe n’itanura rishyushya, hamwe nibirimo ogisijeni, imyuka y’amazi (agaciro k’amazi y’amazi) cyangwa agaciro k’ikime hamwe n’ibirimo amazi ( G garama / KG ku kilo) nubushuhe bwa RH. Umukoresha arashobora kugenzura ubushyuhe bwa gaze yumuriro murwego runaka hejuru gato gato yikigereranyo cyikime cya acide ya gaz ya flue ukurikije kwerekana igikoresho cyangwa ibimenyetso bibiri 4-20mA bisohoka, kugirango wirinde kwangirika kwubushyuhe buke no kongera umutekano wibikorwa byo guteka.
Mu nganda zikora inganda cyangwa amashyanyarazi, gutunganya peteroli ninganda zikora imiti n’itanura. Ibicanwa biva mu kirere (gaze gasanzwe, uruganda rutunganya gaze, amakara, amavuta aremereye, nibindi) bikoreshwa nkibicanwa.
Ibicanwa birimo byinshi cyangwa bike umubare munini wa sulfure, uzabyara SO2murwego rwo gutwika peroxide. Bitewe no kubaho kwa ogisijeni irenze mu cyumba cyaka, umubare muto wa SO2irusheho guhuza hamwe na ogisijeni kugirango ikore SO3, Fe2O3na V.2O5mubihe bisanzwe birenze ikirere. (gaz ya flue hamwe nicyuma gishyushye kirimo iki gice).
Hafi ya 1 ~ 3% ya SO yose2Byahinduwe Kuri SO3. RERO3gaze mu bushyuhe bwo hejuru ya gazi ntishobora kwangiza ibyuma, ariko iyo ubushyuhe bwa gaze ya flue igabanutse munsi ya 400 ° C, NUKO3izahuza hamwe numwuka wamazi kugirango ubyare umwuka wa acide sulfurike.
Inzira yo kubyitwaramo niyi ikurikira:
SO3+ H.2O ——— H.2SO4
Iyo aside ya sulfurique yegeranye hejuru yubushyuhe umurizo w itanura, hazabaho kwangirika kwubushyuhe buke bwa acide sulfurike.
Muri icyo gihe, amazi ya acide sulfurike yegeranye hejuru yubushyuhe bwo hasi nayo azafatira ku mukungugu uri muri gaze ya flue kugirango akore ivu rifatika bitoroshye kuvanaho. Umuyoboro wa gazi ya flue urahagaritswe cyangwa ugahagarikwa, kandi kurwanya biriyongera, kugirango byongere ingufu zumuriro wumuriro uteganijwe. Kwangirika no guhagarika ivu bizabangamira imikorere yubushyuhe bwo hejuru. Kubera ko gaze ya flue irimo SO byombi3n'umwuka w'amazi, bazabyara H.2SO4imyuka, bigatuma kwiyongera kw'ikime cya acide ya gaze ya flue. Iyo ubushyuhe bwa gaze ya flue iri munsi yubushyuhe bwa acide ya acide ya gaz ya flue, H.2SO4icyuka kizubahiriza flue nubushyuhe bwo gukora H.2SO4igisubizo. Ibindi byangiza ibikoresho, bikaviramo guhinduranya ubushyuhe no kwangiza flue.
Mu bikoresho bifasha itanura cyangwa gushyushya, gukoresha ingufu za flue hamwe noguhindura ubushyuhe bingana na 50% byingufu zose zikoreshwa mubikoresho. Ubushyuhe bwa gaze ya gazi bugira ingaruka kumikorere yubushyuhe bwo gushyushya itanura na boiler. Ubushyuhe buringaniye, nubushyuhe bwo hasi. Kuri buri 10 ° C kwiyongera k'ubushyuhe bwa gaze ya gaze, ubushyuhe bwumuriro buzagabanuka hafi 1%. Niba ubushyuhe bwa gaze ya gaze iri munsi yubushyuhe bwa acide ya acide ya gaz ya flue, bizatera ibikoresho kwangirika kandi bitere umutekano muke kumikorere yitanura nubushyuhe.
Ubushyuhe buringaniye bwo gushyushya itanura na boiler bigomba kuba hejuru gato yubushyuhe bwikime cya acide ya gaze ya flue. Kubwibyo, kumenya ubushyuhe bwikime cya acide yubushyuhe bwo gutanura no guteka ni urufunguzo rwo kuzamura imikorere yumuriro no kugabanya ingaruka zumutekano muke.
