Uyilo kunye nokwakhiwa kwesithando sokuvelisa i-hydrogen
Isishwankathelo:
Isithando somlilo esivelisa ihydrogen sisithando somlilo esifudumezayo esisebenzisa ipetroliyam kunye negesi yendalo njengezinto eziluhlaza ukuvelisa ihydrogen ngokusebenzisa i-alkane cracking reaction. Ulwakhiwo lwesithando somlilo lufana kakhulu nolwesithando somlilo esiqhelekileyo esifudumezayo, kwaye kukho iintlobo ezimbini zesithando somlilo: isithando somlilo esisilinda kunye nesithando sebhokisi, ngasinye sazo senziwe yigumbi lemitha kunye negumbi le-convection. Ubushushu kwigumbi elikhanyayo budluliselwa ikakhulu yimitha, kwaye ubushushu kwigumbi le-convection budluliselwa ikakhulu yi-convection. Ubushushu benkqubo ye-alkane cracking reaction ngokubanzi yi-500-600°C, kwaye ubushushu besithando segumbi lemitha ngokubanzi yi-1100°C. Ngenxa yeempawu ezingentla zesithando somlilo esivelisa ihydrogen, i-fiber lining isetyenziswa kuphela kwiindonga kunye nomphezulu wegumbi lemitha. Igumbi le-convection ngokubanzi liphonswa nge-refractory castable.
Ukuchonga izinto zokubopha ilayini:
Ukuqwalasela ubushushu besithando (ngesiqhelo malunga ne-1100℃) kunye nomoya obuthathaka wokunciphisa isithando somlilo se-hydrogen kunye namava ethu oyilo nokwakha iminyaka emininzi kunye nenyaniso yokuba inani elikhulu lezitshisi lisasazwa ngokubanzi kwisithando somlilo phezulu nasezantsi nasemacaleni odonga, izinto zomphetho wesithando somlilo se-hydrogen zichongiwe ukuba ziquka umphetho wezitena ezikhanyisiweyo ze-CCEFIRE oziimitha ezili-1.8-2.5 ubude. Iindawo eziseleyo zisebenzisa izinto zefayibha ye-ceramic ze-CCEWOOL zirconium aluminium njengezinto ezishushu zomphezulu we-lining, kwaye izinto zomphetho we-lining zezinto zefayibha ye-ceramic kunye nezitena ezikhanyisiweyo zisebenzisa iingubo zefayibha ye-ceramic ze-CCEWOOL HP.
Ulwakhiwo lwelayini:
Ngokwendlela ezisasazwa ngayo ii-nozzles ze-burner kwi-oven ye-hydrogen production, kukho iintlobo ezimbini zezakhiwo ze-oven: i-oven ye-cylindrical kunye ne-oven yebhokisi, ngoko ke kukho iintlobo ezimbini zezakhiwo.
Isithando somlilo esisilinda:
Ngokusekelwe kwiimpawu zesakhiwo sesithando somlilo esisilinda, inxalenye yesitena esikhanyayo ezantsi kweendonga zesithando segumbi elikhazimlayo kufuneka ifakwe iithayile ngeengubo zefayibha ze-ceramic ze-CCEWOOL, emva koko ifakwe izitena ze-CCEFIRE ezikhanyayo; iindawo eziseleyo zinokufakwa iithayile ngeeleya ezimbini zeengubo zefayibha ze-ceramic ze-CCEWOOL HP, emva koko ifakwe iinxalenye zefayibha ze-ceramic ze-zirconium aluminium kwisakhiwo se-herringbone anchoring.
Umphezulu wesithando somlilo usebenzisa iileya ezimbini zeengubo zefayibha ze-ceramic ze-CCEWOOL HP, uze emva koko upakishwe ngeemodyuli zefayibha ze-ceramic ze-zirconium aluminium kwisakhiwo se-anchor esixhonywe ngomngxuma omnye kunye neemodyuli ezisongwayo ezidityaniswe eludongeni lwesithando somlilo kwaye ziqiniswe ngezikrufu.
Isithando somlilo sebhokisi:
Ngokusekelwe kwiimpawu zesakhiwo sesithando sebhokisi, inxalenye yesitena esikhanyayo ezantsi kweendonga zesithando segumbi elikhazimlayo kufuneka ifakwe iithayile ngeengubo zefayibha ze-ceramic ze-CCEWOOL, ize ibekwe ngezitena ze-refractory ezikhazimlayo ze-CCEFIRE; ezinye zingafakwa iithayile ngeeleya ezimbini zeengubo zefayibha ze-ceramic ze-CCEWOOL HP, ize ibekwe ngezinto zefayibha ze-aluminium ze-zirconium kwisakhiwo se-anchor yesinyithi se-angle.
Umphezulu wesithando somlilo usebenzisa iileya ezimbini zethayile zeengubo zefayibha ze-ceramic ze-CCEWOOL HP ezifakwe iimodyuli zefayibha ze-ceramic ze-zirconium aluminium kwisakhiwo se-anchor esixhonywe ngomngxuma omnye.
Ezi ntlobo zimbini zesakhiwo seenxalenye zefayibha ziqinile xa zifakelwa kwaye zilungiswa, kwaye ulwakhiwo lukhawuleza kwaye lulula ngakumbi. Ngaphezu koko, kulula ukuziqhekeza nokuzihlanganisa ngexesha lokugcinwa kwazo. I-lining yefayibha icocekile kakuhle, kwaye ukusebenza kwe-insulation yobushushu kuyamangalisa.
Uhlobo lolungiselelo lokufakelwa kwe-fiber lining:
Ngokweempawu zesakhiwo sokubambelela seenxalenye zefayibha, iindonga zesithando somlilo zisebenzisa iinxalenye zefayibha "herringbone" okanye "angle iron", ezicwangciswe kwicala elinye kwicala lokusonga. Iingubo zefayibha zezinto ezifanayo phakathi kwemigca eyahlukeneyo zisongwa zibe yi-U ukuze zibuyisele ukuncitshiswa kwefayibha.
Kwizinto zefayibha zokuhombisa umngxuma ophakathi ezifakwe kumgca ophakathi ukuya kumphetho wesithando somlilo esisilinda phezulu kwesithando somlilo, kusetyenziswa ulungiselelo "lomgangatho weparquet"; iibhloko zokugoba ezisemaphethelweni ziqiniswe ngezikrufu ezidityanisiweyo kwiindonga zesithando somlilo. Iimodyuli zokugoba ziyanda kwicala eliya eludongeni lwesithando somlilo.
Izixhobo zefayibha zokunyusela umngxuma ophakathi phezulu kwesithando sebhokisi zithatha ilungiselelo "lomgangatho weparquet".
