Ukusetyenziswa kwejenereyitha yenitrogen kwindawo yokomba amalahle

Umongo we nitrogen Isitofu sothintelo lomlilo kunye nokucima umlilo kukufakela ukuhamba okuthile kwenitrogen kwindawo ye-oxidation okanye indawo yomlilo webhokhwe, ukunciphisa umxholo wayo weoksijini ube ngaphantsi kwe-10% okanye i-3%, ukuphumeza injongo yokuthintela umlilo, ukucima, kunye nokucinezela ukuqhuma kwegesi. Imisebenzi yayo ibandakanya:

Ukuphelisa ingozi yokuqhuma kwegesi

Xa kuthe kwakho umlilo kwibhokhwe yomgodi wamalahle, eyona ngozi inkulu kukudubula kwerhasi exutyiweyo ngaphakathi. Ngokonxantathu wokuqhuma kwegesi edibeneyo, ukuba umxholo we-oksijeni kwigesi edibeneyo ingaphantsi kwe-12%, kukho ithuba lokunciphisa ukuqhuma. Nangona kunjalo, umda wokuqhuma kwegesi edibeneyo ayixhomekanga kuphela kwipesenti yale gesi emoyeni, kodwa kunye nobushushu kunye noxinzelelo lwegesi edibeneyo. Ukunyuka kweqondo lokushisa kunye noxinzelelo kwandisa lo mda, kwaye ngokuphambene. Ukuba irhasi exutyiweyo ifudunyezwa ukuya kuma 300 ℃ kunye nomxholo weoksijini yi-9%, ugqabhuko-dubulo lungenzeka.

Isiphumo sokupholisa

Kwiindawo zeebhokhwe ezineengozi zomlilo zangaphakathi, ubushushu babo buphezulu kunobushushu bangaphandle. Xa initrogen isetyenziselwa ukucima umlilo, nokuba initrogen engamanzi okanye initrogen isetyenziswa, ubushushu be nitrogen isezantsi kunobushushu berhasi kwindawo yomlilo. Ukongezelela, uluhlu lokuhamba kwe-nitrogen emva kokutofa kwindawo yomlilo likhulu, elinomphumo obalulekileyo wokupholisa kwibhokhwe.

Thintela ukufudumeza kwendalo kunye nokutshiswa kwamalahle okuzenzekelayo

Izinto ezithathu zokutsha kwamalahle zezi: Kukho iimeko zokubonelela ngeoksijini ngokuqhubekayo; Ubushushu buthanda ukufumba. Ukuba ukuvuza komoya kwindawo ye-oxidation yebhokhwe kubuso bemveliso yomgodi wamalahle akonelanga ukususa ubushushu obuveliswa yi-oxidation yamalahle, ubushushu bamalahle buyanda ngokuthe ngcembe, kwaye amalahle akwimo yendalo yokufudumeza. Xa iqondo lokushisa lifikelela ngaphezu kobushushu obubalulekileyo bamalahle, i-oxidation kunye nokuhlanganiswa ngokukhawuleza kukhawuleza, ukuvelisa ubushushu obukhulu kwaye kubangela ukuba ukushisa kwamalahle kunyuke ngokukhawuleza. Xa ubushushu bomlilo wamalahle bufikelelwe, luyavutha kwaye lutshise, lungene kwindawo yokutsha ngokuzenzekelayo. Ukutofa isantya esithile sokuhamba kwenitrogen kwindawo ye-oxidation yebhokhwe ebusweni bokusebenza ukunciphisa umthamo we-oksijini kwindawo, eyona nto iphambili ekutshabalaliseni ukutsha kwamalahle okuzenzekelayo, kunye nokunciphisa umxholo wayo we-oksijini ngaphantsi kwexabiso elibalulekileyo lokutsha kwamalahle okuzenzekelayo, ngaloo ndlela kufezekiswa injongo yokuthintela ukutsha kwamalahle okuzenzekelayo.
