Kwimimandla etshintsha rhoqo yezicelo zokwakha nezemizi-mveliso, imfuno yezinto ezisemgangathweni ophezulu ibaluleke kakhulu. Phakathi kwezi zinto, iityhubhu zesakhiwo ezingenanto ziye zaba sisisombululo esisebenzisekayo kwiintlobo ngeentlobo zezicelo, ingakumbi kwicandelo lokwakha, iikhemikhali zepetroli kunye neenkqubo zebhoyila ezinobushushu obuphezulu.
Eyona nto iphambili kushishino yinkampani ekhokelayo eseCangzhou, kwiPhondo laseHebei. Yasekwa ngo-1993, le nkampani ikhule ngokukhawuleza kule minyaka idlulileyo, igubungela indawo yeemitha zesikwere ezingama-350,000 kunye neempahla zizonke ezizizigidi ezingama-680 zeeyuan. Ngabasebenzi abazinikeleyo abangama-680 kunye nezixhobo ezigqwesileyo, le nkampani iyakwazi ukuhlangabezana neemfuno ezahlukeneyo zabathengi.
Enye yeemveliso ezibalaseleyo ezinikezelwa yile mveliso luluhlu olubanzi lweetyhubhu ze-alloy, ezifumaneka ngobukhulu obuqala kwiisentimitha ezi-2 ukuya kwiisentimitha ezingama-24. Zenziwe ngezinto ezikumgangatho ophezulu ezifana ne-P9 kunye ne-P11, ezi tyhubhu zilungele ukusetyenziswa kwiindawo ezinobushushu obuphezulu. Usetyenziso lwazo oluphambili lubandakanya iindawo zokufudumeza kwiibhoyila ezinobushushu obuphezulu, ii-economizers, ii-headers, ii-superheaters, kunye nee-reheaters. Ngaphezu koko, ezi tyhubhu ze-alloy zizinto ezibalulekileyo kwishishini le-petrochemical, apho ukuqina kunye nokumelana neemeko ezinzima kubaluleke kakhulu.
Le nkampani ivelisaimibhobho yesakhiwo esingenamngxumaezinika amandla angaqhelekanga kunye nozinzo kwiintlobo ngeentlobo zezicelo. Ubume bazo obukhethekileyo buvumela ukusasazwa komthwalo ngokufanelekileyo, nto leyo eluncedo kakhulu kwiiprojekthi zokwakha apho ukuqina kwesakhiwo kubaluleke kakhulu. Nokuba zisetyenziswa kwizakhelo zokwakha okanye njengenxalenye yeenkqubo zoshishino ezintsonkothileyo, ezi tyhubhu zibonelela ngokuthembeka kunye nokusebenza okunokuthenjwa ziinjineli kunye nabayili bezakhiwo.
Enye yezona nzuzo ziphambili zeepayipi ezakhiweyo ezingenanto kukwazi kwazo ukumelana noxinzelelo oluphezulu kunye namaqondo obushushu. Oku kuzenza zilungele amashishini afuna izixhobo ezinokumelana neemeko ezinzima. Umzekelo, kushishino lwe-petrochemical, ezi payipi zihlala zichaphazeleka zizinto ezirhabaxa kunye namaqondo obushushu aphezulu. Iipayipi ze-alloy ezinikezelwa ngulo mvelisi zenzelwe ukumelana nemingeni enjalo, ukuqinisekisa ubomi benkonzo ende kunye nokusebenza ngokukhuselekileyo.
Ngaphezu koko, ukuguquguquka kweetyhubhu zesakhiwo ezingenanto akupheleli nje kwizicelo zoshishino. Zikwasetyenziswa ngakumbi kuyilo lwezakhiwo, apho ubuhle bazo kunye neenzuzo zesakhiwo zinokuphucula inkangeleko iyonke yeprojekthi. Ukususela kwizakhiwo ezinde zanamhlanje ukuya kwiibhulorho ezintsha, ezi tyhubhu ziba zizinto ezibalulekileyo kuyilo lwezakhiwo lwanamhlanje.
Lilonke, iityhubhu zesakhiwo ezingenanto eziveliswe ngulo mvelisi waseCangzhou zimele umxube womgangatho, ukuqina, kunye nokuguquguquka. Ngesitokhwe seetyhubhu ze-alloy eziqala kwii-intshi ezi-2 ukuya kwii-intshi ezingama-24, kunye neendidi ezifana ne-P9 kunye ne-P11, inkampani iyakwazi ukukhonza amashishini ahlukeneyo afana neenkqubo zebhoyila ezinobushushu obuphezulu kunye neekhemikhali zepetrochemicals. Njengoko imfuno yezixhobo ezinokuthenjwa nezisebenza kakuhle iqhubeka ikhula, lo mvelisi ukulungele ukuhlangabezana nemingeni yehlabathi lanamhlanje kwaye aqinisekise ukuba abathengi bakhe banokufikelela kwiimveliso ezilungileyo. Nokuba zisetyenziswa ekwakheni, kwizicelo zoshishino okanye kuyilo lwezakhiwo ezintsha, iityhubhu zesakhiwo ezingenanto ngokungathandabuzekiyo ziyinxalenye ebalulekileyo yokubumba ikamva leziseko zophuhliso.
