Umwuka uhumanya uturuka ku musaruro wa sima ahanini ni umukungugu na gaze ya flue.

Umukungugu ahanini uturuka muburyo bukurikira:
1.ibikoresho byo gutegura ibikoresho
A.CaCO3.
B.Kuma
C. Gusya amakara no kugaburira.
D. Gusya ibyokurya bisya.

Sisitemu yo gutwika ya clinker izananiza umwuka wumukungugu.

3.Kurangiza gutunganya umusaruro:
A.Isyo ya sima
B. Gupakira sima
C. Ubwikorezi bwinshi bwa sima.

Kugirango hategurwe ibikoresho fatizo A, C, D nuburyo bwo kurangiza umusaruro umwuka wumukungugu uzana nubushyuhe bwo hasi, ariko gutegura ibikoresho bibisi B, umwuka wumukungugu unaniza mumutwe numurizo witanura burigihe hamwe nubushyuhe bwo hejuru.

Ibice bigize umwuka wumukungugu cyane cyane ni CaCO3 ， CaO ， SiO2 ， Fe2O3 ， Al2O3 ， MgO ， Na2O ， K2O, nibindi.

Kubyuka bya flue biva mumasima ya sima ahanini ni SO2, NOx, CO2, HF, nibindi biva mukubora kwa CaCO3 no gutwika lisansi.

SO2 ikomoka kumafunguro mbisi (ifu yumukara cyangwa igice cyumukara wifu wibiryo byahagaritswe), gutwika lisansi;
NOx iva mubitekerezo hagati ya N2 na Oxygene mubushyuhe bwinshi;
HF iva mubigize fluor ibora bivuye kumafunguro mbisi mugihe cyo gutwika, nko kuvanga na fluorite nka minisiteri mu itanura rihagaze.

CO2 ituruka ahanini kubora kwa CaCO3, gutwika lisansi, nibindi.

Ibisubizo:
1.Ku kugenzura ikirere
Zonel filtech irashobora gutanga akayunguruzo k'umukungugu wo gukusanya ivumbi kugirango isukure ikirere, irashobora kandi gutanga ibikoresho bijyanye ukurikije ibyo abakiriya bakeneye.
Umufuka muyungurura uva muri Zonel filtech hamwe nubushakashatsi buhanitse bwo hejuru, ndetse no kuri 0.5 micron ibice, gushungura birashobora kugera kuri 99,99%, kandi muyungurura burigihe hamwe nibikorwa bihamye, byoroshye kubungabunga.
Inzu ya Zonel yamashanyarazi inzu irashobora gukusanya ivumbi ridashobora gufatwa na cottrell, nkumukungugu ufite ibintu byiza cyane cyangwa bibi cyane.

2.Ku kugenzura gaz ya flue
CO2: kuzamura ubwiza bwa clinker; kugabanya ikoreshwa rya clinker, nko guteza imbere ibikoresho bimwe bivanga hashingiwe kumiterere imwe ya sima, koresha bimwe bisimbuza sima icyatsi kugirango ugabanye ikoreshwa rya sima; guteza imbere sisitemu nziza yo gukoresha ubushyuhe bwimyanda, nko gukoresha ubushyuhe bwimyanda kugirango wumishe ibikoresho bibisi, koresha ubushyuhe bwimyanda kubyara amashanyarazi, nibindi.

SO2:
Hindura ibikoresho byiza bibisi, gabanya ibirimo bya sufuru;
Kunywa mu ruganda mbisi: kuyobora umwuka wumukungugu kuva umurizo w itanura kugeza kumasyo mbisi, reaction nkiyi:
CaCO3 + SO2 = CaSO3 + CO2
2 CaCO3 + 2 SO2 + O2 = 2 CaSo4 + 2 CO2
Kuvanga Ca (OH) 2;
Gutunganya umunara wo kwiyuhagiriramo;
Kandi igisubizo cyiza cyane ni uguhitamo ikigereranyo cya Sufuru na alkali;
Muri icyo gihe, ku murizo w’itanura, shyiramo ibikoresho byo muyungurura imifuka ikusanya ivumbi, Na2O ， K2O hejuru yimifuka yungurura ivumbi izitwara hamwe na SO2 na NO2, ibirimo umwuka wa aside birashobora kugabanya 30 ~ 60 %.

NOx:
Komeza ubushyuhe bukwiye, ugenzure ingano yumwuka;
Koresha gaze igabanya, nka CO, H2, nibindi, vanga Fe2O3, Al2O3 kumafunguro mbisi, ashobora kugabanya NOx kuri N2.
2NO + 2CO = N2 + CO2;
2NO + 2H2 = N2 + 2H2O
2NO2 + 4CO = N2 + 4 CO2
2NO2 + 4H2 = N2 + 4H2O

Ukurikije ibikorwa, rero ku itanura ugomba kugenzura neza O2 witonze.

Kugabanya catalitike yatoranijwe nayo irashobora gufasha kugabanya NOx irambiranye, iki gisubizo kirimo gushyiramo kugabanya kugabanya, nka hydrogène nitride cyangwa Urea:
8NH3 + 6NO2 -> 7N2 + 12H2O
6NO + 4NH3 -> 5N2 + 6H2O
4NH3 + 3O2 -> 2N2 + 6H2O
