Li-nozzle tsa Silicon Carbide (SiC) tsa Burner

Mekhoa ea mocheso o phahameng moo taolo ea mokelikeli, khanyetso ea khoholeho ea mobu le botsitso ba mocheso li leng bohlokoa,li-nozzle tsa silicon carbide (SiC)E hlahella e le mohlolo oa boenjiniere. Ho fapana le li-nozzle tsa ceramic kapa tsa tšepe tse tloaelehileng, thepa e ikhethang ea SiC e sebetsana le liphephetso lits'ebetsong tsa ho chesa, ho tsamaisa le ho fafatsa tsa indasteri. Sengoloa sena se hlahloba hore na ke hobane'ng ha liindasteri li ntse li sebelisa li-nozzle tsa SiC ka ho eketsehileng ho fetola ts'ebetso lits'ebetsong tse thata ka ho fetisisa.

1. E entsoe bakeng sa Tikoloho e Feteletseng ea Metsi

Li-nozzle tsa SiC li ipabola ho laoleng lebelo le phahameng, maro le likhase tse futhumatsang mocheso o phahameng:

（1）Khanyetso ea khoholeho ea mobu: E mamella likaroloana tse khorofo tse kenngoang ka har'a li-injector tsa mashala, litsamaiso tsa ho phatloha ha lehlabathe, kapa li-propellant tsa rokete ntle le ho senyeha ho bakoang ke ho tsofala.

（2）Ho Pholoha ha Thermal Shock: E potoloha ka potlako pakeng tsa mocheso o feteletseng (mohlala, ho kenngoa ha mafura ka har'a lionto tsa tšepe) ntle le ho petsoha, ka lebaka la katoloso e tlase ea mocheso oa SiC.

（3）Ho se Sebete ha Lik'hemik'hale: Hanela ho bola ho bakoang ke li-spray tse nang le asiti/alkaline, matsoai a qhibilihisitsoeng, kapa malakabe a oxidizing, ho netefatsa hore sebopeho sa lesoba se tsitsitse.

2. Taolo ea Phallo e Nepahetseng bakeng sa Mekhoa ea Bohlokoa

Lits'ebetsong tse hlokang ho nepahala ha boemo ba micron, li-nozzle tsa SiC li fana ka ts'epo e ke keng ea lekanngoa:

（1）Jiometri e Tsitsitseng ea Orifice: Boloka sekhahla se nepahetseng sa phallo le mekhoa ea ho fafatsa esita le ka mor'a ho pepesehela tikoloho ea 1500°C+ nako e telele, ho fapana le litšepe tse kobehang kapa tsa letsopa tse senyehang.

（2）Ho Koaleha ho Fokotseng: Qetello ya bokaholimo bo boreleli haholo e fokotsa ho bokellana ha thepa ka har'a li-injector tsa mafura kapa litsamaiso tsa spray tsa lik'hemik'hale.

（3）Mamello e Phahameng ea Khatello: E mamella khatello ea hydraulic e fetang 500 MPa, e loketse ho seha jete ea metsi kapa ho tsamaisa sefofane.

3. Ho nolofalletsa ho tuka ha motlakase ka bokgoni bo phahameng

Li-nozzle tsa SiC li bohlokoa haholo ho ntlafatseng litsamaiso tsa ho chesa tse sebelisang matla a mangata:

（1）Botsitso ba Mollo: Moralo o hanelang mocheso o netefatsa ho kopanngoa ha mafura le moea ka ho lekana ka har'a li-turbine tsa khase kapa li-burner tsa indasteri, e leng se fokotsang libaka tse chesang le mesi e tsoang NOx.

（2）Ho Tenyetseha ha Mafura: E lumellana le haeterojene, mafura a tlhaho, kapa oli e boima, e tšehetsang phetoho ea mehloli ea matla a tsitsitseng.

（3）Bokgoni ba ho Futhumatsa: Fokotsa tahlehelo ya mocheso maboteng ka lebaka la ho tsamaisa mocheso ho hoholo ha SiC, ho ntlafatsa bokgoni ba kamore ya ho tuka ka ho fihlela ho 15%.

Shandong Zhongpeng Special Ceramics Co., Ltd ke e 'ngoe ea litharollo tse kholo ka ho fetisisa tsa thepa e ncha ea silicon carbide Chaena. SiC technical ceramic: Bothata ba Moh ke 9 (Bothata ba Moh bo bocha ke 13), bo nang le khanyetso e ntle khahlanong le khoholeho le mafome, khanyetso e ntle - khanyetso le anti-oxidation. Bophelo ba tšebeletso ea sehlahisoa sa SiC bo bolelele ka makhetlo a 4 ho isa ho a 5 ho feta thepa ea alumina ea 92%. MOR ea RBSiC e feta ka makhetlo a 5 ho isa ho a 7 ho feta SNBSC, e ka sebelisoa bakeng sa libopeho tse rarahaneng haholoanyane. Ts'ebetso ea khotheishene e potlakile, phano e etsoa joalo ka ha e tšepisitsoe 'me boleng ha bo fete letho. Kamehla re phehella ho phephetsa lipheo tsa rona 'me re khutlisetsa lipelo tsa rona sechabeng.
