Izinto ezivuselelayo ezisetshenziswa kuhhavini ojikelezayo wemfucuza enobungozi zifakwa i-calcium ngezingxenye eziyinkimbinkimbi nezingazinzi. Inhloso ye-calcium iwukushisa imfucuza enobungozi ibe yi-slag nokunciphisa izinga lokunciphisa ukushisa kwezinsalela libe ngaphansi kuka-5%. uma kungekho uqweqwe kuhhavini, indlela yokukhetha i-resictor ye-hazardous waste incinerator rotary kiln ihluke ngokuphelele kuhhavini ojikelezayo.
Ngezinto ezivimbela ukubola ezisetshenziswa kuhhavini ojikelezayo wokwelapha imfucuza eyingozi, ukwakheka kwamakhemikhali kwemfucuza eyingozi kuyinkimbinkimbi ngenxa yezinhlobo zayo ezahlukahlukene, ngakho-ke kunqunywa ukuthi ukwakheka kwamakhemikhali kwemfucuza eyingozi kushiswe ekushiseni okungu-700-1000 kumahhavini ojikelezayo, kanti ukwakheka okuyinhloko kokukhishwa kwegesi ngemva kokuncibilikiswa kwemfucuza eyingozi kuyi-asidi encane.
Ku-refractory, refractory castable to acidic gas inokuqina okuhle, i-AL2O3 SiO2 waste rotary kiln iyindlela enhle yokumelana nokugqwala kanye ne-castable refractory, lapho ukhetha izinto eziphikisayo, hhayi ukukhethwa kwemikhiqizo ephikisayo, okuqukethwe kwe-Fe2O3 ngangokunokwenzeka ngenxa ye-Fe2O3 FeCL3 isabela negesi ye-chlorine, isigaba segesi, sishintshashintsha futhi silinganisela ngokweqile izitini eziphikisayo, i-cement rotary kiln ivame ukusetshenziswa ekumelaneni nokugqwala komkhiqizo wokuvikelwa kwemvelo. I-Magnesia iron spinel brick, ku-hazardous waste rotary kiln ukukhetha izinto eziphikisayo akufaneleki, ku-hazardous waste rotary kiln feed kanye ne-outlet castable, kufanele futhi kukhethwe i-low castable cement, ngoba i-samente CaO kanye ne-chlorine reaction, ukwakheka kwe-liquid phase CaC1 kuzonciphisa ukumelana nokushisa kanye nokuqina kokushisa okuphezulu kwe-castable.
Ekukhetheni izinto ezivimbela ukugqwala, i-oven rotary kiln enobungozi kufanele isebenzise izinto ezivimbela ukugqwala kahle, ukuqina kokushaqeka kokushisa kanye nokumelana nokugqwala. Inqubo yokukhiqiza i-oven rotary kiln enobungozi ngokuvamile isebenzisa inqubo yokushiswa phansi. I-oven eyingozi yomoya oyinhloko ingena isuka ohlangothini olulodwa futhi ubude be-oven bufushane (isilinganiso sobude nobubanzi ngokuvamile singamamitha angu-3-5 kuphela). Ukusabela ku-oven kulula, okungukuthi, ukusabela kwe-oxidation yokushisa. Phakathi kwemikhiqizo esetshenziswa kakhulu njengamanje, i-mullite sic brick ingumkhiqizo ofaneleka kakhulu, futhi izinto ezingasetshenziswa zingakhethwa njenge-mullite.
