Mumabasa emaindasitiri anodziya zvakanyanya, mashandiro ezvinhu zvinoramba kugadzirwa anosarudza zvakananga kushanda zvakanaka kwekugadzira, kuchengetedzeka, uye kudzora mitengo.Simende Yakaderera Inokandirwa (LCC)Yakabuda semhinduro inochinja-chinja zvinhu, ine huwandu hushoma hwecalcium oxide (≤3%) uye simende shoma (3%-8%), iyo inopa hunhu hwakanaka hwekuramba kusimba kana tichienzanisa nemidziyo yechinyakare inokandirwa. Inodzivirira kupisa zvakanyanya, inodzivirira kukurwa kweslag, uye simba rekupisa zvakanyanya zvinoita kuti ive yakakosha mumaindasitiri akasiyana-siyana pasi rese.
Indasitiri yesimbi ndiyo inonyanya kubatsirwa nesimbi isingadhuri, uko inobudirira munzvimbo dzine kupisa kwakanyanya. Inoshandiswa zvakanyanya pakuisa machira ekupisa, machira ekupisa, uye makiln anotenderera, pamwe chete nemachira emagetsi ekupisa uye machira ekupisa. Pakugadzira simbi, LCC inopa dziviriro yakavimbika kumachira, matundishes, uye maturu ekupisa, ichidzivirira ngura kubva kusimbi yakanyungudutswa nesimbi yakatsvuka uku ichichengetedza chimiro chayo patembiricha inosvika 1800℃. Musimbi dzisina ferrous, yakanakira machira ekubata aruminiyamu, machira ekuwachisa, uye machira emagetsi, nekuda kwekuwedzera kunoderedza kupinda kwesimbi yakanyungudutswa.
Indasitiri yesimende inonyanya kushandisa simende shoma kuti iwedzere kugara kwenguva refu kwemidziyo mikuru inodziya. Inowanzo shandiswa pakilneye yekumashure, chifukidziro chewicket, uye kumashure kunotonhorera kwekiln inotenderera yesimende, uko inotsungirira kupisa kwakanyanya uye zvinhu zvinokwesha, zvichiita kuti nguva yekushanda kwemidziyo iwedzere zvakanyanya. Kuderera kwayo uye kuwanda kwayo kunodzivirira kurasikirwa nekupisa, kuvandudza kushanda kwesimba uye kuderedza nguva yekushanda kwekugadzirisa - zvinhu zvakakosha kune vagadziri vesimende vari kutsvaga kuderedza mari.
Kupfuura simbi nesimende, simende shoma inokandwa inoshanda mabasa akasiyana-siyana muindasitiri ye petrochemical, magetsi, uye marara. Mumafekitori e petrochemical, inoisa ma catalytic cracking reactors nemapaipi anodziya zvakanyanya, ichidzivirira kukurwa kwemakemikari uye kupisa. Pakugadzira magetsi, inoshandiswa mumakamuri ekupisa e boiler, ma flue, uye ma cyclone separator, ichidzivirira kubva pakupisa kwakanyanya uye ngura ye flue gas. Inoshandawo zvakanaka mu incinerators dzemarara, uko inodzivirira ngura kubva kuma flue gases akaomarara, ane chepfu uye abrasive ash particles.
Kugona kwayo kugadzira zvinhu zvakasiyana-siyana zvesimbi isina simende kunowedzerwawo nekushandiswa kwayo kwekuvaka kunochinjika. Inowanikwa semhando dzinodedera kana dzinozvifambisa dzoga, inogona kuumbwa, kusvibirwa, kana kupombwa panzvimbo yacho, ichichinja kuita zvinhu zvakaoma nenzvimbo dzakaoma kusvika pasina kukanganisa mashandiro ayo. Simba rayo rekupisa kwepamusoro rinowedzera kana ichipiswa, zvichikunda kushaya simba kwesimbi dzesimbi dzechinyakare dzinorasikirwa nesimba pa800-1200℃.
Ingave iri ye maovheni eindasitiri akakosha, simbi yakanyungudutswa, kana mapaipi anodziya zvakanyanya, simende shoma inokandwa inopa kushanda kwakasimba uye kwenguva refu. Musanganiswa wayo wekugara kwenguva refu, kushanduka-shanduka, uye kushanda nesimba kunoita kuti ive mhinduro inosarudzwa yeindasitiri dzemazuva ano dzinodziya zvakanyanya. Sarudza LCC kuderedza mari yekugadzirisa, kuvandudza kuchengetedzeka kwekushanda, uye kuzadzisa zvinangwa zvekugadzira zvinogara kwenguva refu.
