Summary: Ubhontshisi wehauku ungesinye sezinkinzuzo ezinkulu embonini zokulahla udoti e-China. Ngokuthuthukiswa kwezimboni zamandla, ubungako bebhontshisi wehauku obukhishwa ku-coal...

Isikhunta se-fly ash yisinye sezinto eziphukileyo zezimboni ezinekhulu lokushintsha eChina. Ngenxa yokuqhubeka kokusebenza kwebhizinisi lamanzi, inani lesikhunta se-fly ash esikhishwa yizitshalo zokushisa amalahle liye lakhula unyaka nonyaka. Ngakho, izimbiwa ze-fly ash nazo zithonya inhlalakahle yokuthuthukiswa kwesizwe ngendlela ehlala isikhathi eside. Ngempela, ngifunde emaphephandabeni ukuthi isikhunta se-fly ash, esakuthiwa yinto ephukileyo futhi esikhuliswe, siye saba yinto ebalulekile ekuqeqeshweni kwesikhunta se-fly ash esikhulu semiliyoni ye-kilowatt ezitshalweni zokushisa amalahle ezingaphezu kwezinto eziyisi-supercritical. Akuyona nje kuphela into engeke isasebenzisa indawo yokuhlala,

Kuyiqondwa ukuthi umlotha wamakhala yisisekelo esikhulu esenziwa yi-khola ngesikhathi yokuqhuma. E-China, ngenxa yombalwa wamageyimu e-khola amakhulu, umlotha wamakhala sewumthombo oyedwa wokuhlutha kwezinto eziqinile zezimboni, okuphuma ngonyaka ngaphezu kwetoni ezigidi ezingu-300. Nokho, manje, kunamalungiselelo amaningi nasezindlela e-China ezokwasetshenziswa kabusha umlotha wamakhala. Ngokwesibonelo, i-China Huaneng Yuhuan Power Plant yenzile umzamo omkhulu ukuze ifaka isikhululo sezobuchwepheshe eziphumelelayo emhlabeni wonke ukuze yenze umlotha wamakhala abe yizinto zokwakha. Ngonyaka ophelile, i-Huaneng Yuhuan Power Plant ikwenze okukhulu...

Uchungechunge lwezinto zokugaya luyakwazi ukuguqula ugu olungaphansi komoya ube yipulazi elimihle kakhulu elinanoma iyiphi usayizi wethambo. Ngokukhethekile, esisetshenziswe ngaphambili yayingafinyeleli izidingo zethu zokukhiqiza futhi iphunga le-bentonite elishayeliwe lalingahlangabezani namazinga okuqhubekayo, siye saqeqeshwa ukuthenga amatshe amasha ukuze sikhulise ukukhiqiza. Ngenxa yokumemezela kwabangani, siye senza i- Imishini inenhlangano yesakhiwo esithambile sezinga lesithathu, occupy encane, isethi ephelele yemikhiqizo, ubungako obufanayo bephuze eliphelile, kanye nenzalo yokudlula engu-99%. Uthuli lwemimoya lungase luphathwe lube yindawo yezakhiwo zesakhiwo. Uthuli oluphathwe lungaxutshwa nanoma iyiphi inani elifanele le-gypsum, kanye nenani elithile lezihlabathi ezifana ne-cinder noma izinto ezikhishwe emanzini. Ngemva kokukhipha, ukuxuba, ukubhidliza, ukugaya ngemijikelezo, ukwakha ngokucindezela, nokuvavanywa ngendlela yomoya noma ngokusebenzisa umswakama ophakeme, lungakhiqizwa ibe izinto zodonga. Amabhreki gakulu achotshwe ngobunono abuswayo, kanye nephepha lesimbi, njengento eyisisekelo; ahlukaniswa ngokucutshungulwa kwezinto ezingavuthiwe, ukuxuba, ukwakha, ukomisa kanye nokushisa. Amabhreki wokufaka uthuli oluqhumayo oluyisikhwepha isikhumba esitsha sezindonga ezishisayo, asetshenziswa uthuli oluphambili njengento eyinsika, engeza inani elithile le-lime kanye nomthombo wokuhlaba, futhi akhiqizwa ngokuxuba, ukuxuba, ukushisa nokungena ngaphansi komshini ocindezela. Ngokusebenzisa uthuli oluphambili njengento eyinhloko, engeza inani elifanele le-lime esheshayo, i-cement, i-gypsum kanye nepulazi le-aluminium, xenxa kumanzisa ukwakha i-slurry, bese ufaka kumdaka, kungakhiqizwa izinto zokwakha ezikhanyayo nezine-porosity. Uthuli lwemimoya lwe-ceramsite luhlobo olwenziwe ngesandla oluncane lwe-catching oluqhutshwa ngokusebenzisa uthuli lwe-mimoya njengento eyinhloko, ngokuxuba nenani elincane le-binder kanye nomlilo oqinile, bese kuthiwa anqunywe ngokushisa kakhulu.
