Ekufuneni imveliso yamandla acocekileyo, izitishi zamandla ziya ngokuya zisebenzisa ubuchwepheshe obuphambili ukunciphisa impembelelo yazo kwindalo esingqongileyo. Enye yezi teknoloji kukusebenzisa iinkqubo ze-flue gas desulfurization (FGD), ezidlala indima ebalulekileyo ekunciphiseni ukukhutshwa kwe-sulfur dioxide. Embindini wezi nkqubo kukho ii-nozzles ze-silicon carbide ze-FGD, ezenziwe ngezinto ze-ceramic ezisemgangathweni ezibizwa ngokuba yi-silicon carbide. Le blogi iza kuhlola ukubaluleka kwezi nozzles, utshintsho loyilo lwazo, kunye nempembelelo yazo ekuzinzeni kwendalo.
Ii-nozzles ze-silicon carbide zenzelwe ukwenza lula inkqubo yokukhupha i-sulfurization kwizikhululo zamandla. Umsebenzi wazo oyintloko kukususa i-sulfur dioxide (SO2) kunye nezinye izinto ezingcolisayo eziyingozi kwiigesi ze-flue ezikhutshwa ngexesha lokutsha kwamafutha e-fossil, ingakumbi amalahle. Ukubaluleka kwale nkqubo akunakugxininiswa kakhulu, njengoko i-sulfur dioxide inegalelo elikhulu kwimvula ene-asidi kunye nongcoliseko lomoya, olunokuba nemiphumo emibi kwimpilo yabantu nakwindalo esingqongileyo. Ngokusebenzisa ii-nozzles ze-silicon carbide ze-FGD, izityalo zamandla zinokunciphisa kakhulu ukukhutshwa komoya kwaye zithobele imithetho engqongqo yokusingqongileyo.
Uyilo lwee-nozzles ze-silicon carbide ze-FGD zenzelwe ukuphucula ukusebenza kwazo kwiindlela ezahlukeneyo zokusebenza. Iindidi ezimbini eziqhelekileyo ze-nozzles ezisetyenziswa kwiinkqubo ze-desulfurization yi-spiral full cone nozzle kunye ne-vortex hollow cone nozzle. I-spiral full cone nozzle yenzelwe ukuvelisa inkungu encinci yolwelo olufunxayo, oluphucula unxibelelwano phakathi kolwelo kunye negesi ye-flue, ngaloo ndlela lunyusa ukusebenza kakuhle kwenkqubo ye-desulfurization. I-vortex hollow cone nozzle, kwelinye icala, ivelisa iphethini yokutshiza ejikelezayo esasaza ngcono i-absorbent, iqinisekisa unyango olupheleleyo lwegesi ye-flue. Ukukhethwa kwezi ntlobo ze-nozzle kuxhomekeke kwiimfuno ezithile zesityalo samandla kunye neempawu zegesi ye-flue ephathwayo.
Enye yezona nzuzo ziphambili ze-silicon carbide njengesixhobo se-FGD nozzle kukuqina kwayo okuhle kunye nokumelana nokuguguleka kunye nokubola. Izityalo zamandla zihlala zisebenza phantsi kweemeko ezinzima, kunye namaqondo obushushu aphezulu kunye namasuntswana arhabaxa akhoyo kwigesi yeflue. Iimpumlo ze-silicon carbide zinokumelana nale meko inzima, ziqinisekisa ubomi benkonzo obude kunye neendleko zokugcinwa ezincitshisiweyo. Olu kuqina aluphuculi kuphela ukusebenza kakuhle kwenkqubo yokususa i-sulfurization, kodwa lukwanceda ukuphucula ukuthembeka ngokubanzi kwemisebenzi yezityalo zamandla.
Ukongeza ekususeni i-sulfurization, ii-nozzles ze-FGD SiC zikwadlala indima ekususeni i-nitrification kunye nokususwa kothuli. Igesi yolwelo evela kwizityalo zamandla ezisebenzisa amalahle ayinayo i-sulfur dioxide kuphela, kodwa ikwanayo ne-nitrogen oxides (NOx) kunye nezinto ezincinci. Ngokudibanisa iinkqubo ze-FGD kunye netekhnoloji ye-denitrification, izityalo zamandla zinokunyanga ukungcola okuninzi ngaxeshanye, nto leyo ephucula ngakumbi umgangatho womoya. Ukukwazi ukujongana nale miphumo ihlukeneyo yokukhupha umoya kubalulekile ekuhlangabezaneni nemigangatho yokusingqongileyo kunye nokunciphisa umbane wekhabhoni iyonke kwimveliso yamandla.
Impembelelo yokusingqongileyo yokusebenzisa i-FGD silicon carbide nozzles ibanzi kakhulu. Ngaphandle kokususa i-sulfurization kunye ne-denitrification esebenzayo, ukukhutshwa kwegesi yolwelo oluvela kwizityalo zamandla kunokubangela ungcoliseko lomoya olubi, okukhokelela kwizifo zokuphefumla kunye nokonakaliswa kokusingqongileyo. Ukongeza, ukukhutshwa kwegesi okungacocwanga okuvela kwizityalo zamandla ezisebenzisa amalahle kunokonakalisa iindawo ezishushu zeeturbine zegesi kwiinkqubo zomjikelo odibeneyo, okukhokelela ekulungisweni okubizayo kunye nokungasebenzi kakuhle kokusebenza. Ngokutyala imali kubuchwepheshe obuphambili be-FGD, izityalo zamandla azinakukhusela okusingqongileyo kuphela, kodwa zikwaphucula ukusebenza kwazo kunye nokuphila kakuhle kwezoqoqosho.
Njengoko imeko yamandla yehlabathi iqhubeka nokuguquka, imfuneko yemithombo yamandla ecocekileyo nezinzileyo iya isiba ngxamiseko. Ii-nozzles ze-silicon carbide ze-FGD ziyinxalenye ebalulekileyo yotshintsho oluya kwimveliso yamandla aluhlaza. Ngokususa ngokufanelekileyo ungcoliseko oluyingozi kwiigesi zombhobho, ezi nozzles zinceda izityalo zamandla ukuhlangabezana neemfuno zomthetho kwaye zinegalelo kwiplanethi enempilo. Njengoko ubuchwepheshe buqhubela phambili kunye nemfuno yokugcinwa kwendalo iqhubeka ikhula, indima yee-nozzles ze-silicon carbide ze-FGD ekulweni nongcoliseko lomoya kunye notshintsho lwemozulu ngokuqinisekileyo iya kuba yinto ebaluleke ngakumbi.
Ngamafutshane, i-FGD Silicon Carbide Nozzle yinto entsha ebalulekileyo kwicandelo lokususa i-sulfurization yezityalo zamandla. Uyilo lwayo olukhethekileyo, ukuqina kwayo, kunye nokusebenza kwayo ekususeni i-sulfur dioxide kunye nezinye izinto ezingcolisayo kwenza ukuba ibe yinto ephambili ekufuneni imveliso yamandla acocekileyo. Njengoko izityalo zamandla ziqhubeka nokusebenzisa ubuchwepheshe obuphambili ukunciphisa impembelelo yazo kwindalo esingqongileyo, ukubaluleka kwee-FGD Silicon Carbide Nozzles kuya kwanda, kuvula indlela yekamva elizinzileyo.
