Silicon carbide (SiC) Burner nozzles
Hauv cov txheej txheem kub siab uas tswj cov kua dej, tiv thaiv kev yaig, thiab kev ruaj khov thermal yog qhov tseem ceeb,silicon carbide (SiC) nozzlessawv tawm ua ib qho txuj ci tseem ceeb hauv kev tsim kho. Tsis zoo li cov khoom siv ceramic lossis hlau dav dav, SiC cov khoom tshwj xeeb daws cov teeb meem hauv kev sib xyaw ua ke, kev tsav tsheb, thiab kev txau tshuaj hauv kev lag luam. Tsab xov xwm no tshawb nrhiav vim li cas cov lag luam thiaj li siv SiC nozzles ntau dua los hloov pauv kev ua tau zoo hauv cov ntawv thov uas xav tau ntau tshaj plaws.
1. Tsim los rau Cov Chaw Muaj Kua Ntau Heev
Cov nozzles SiC zoo heev hauv kev tswj cov kua dej thiab cov pa roj uas kub thiab ceev heev:
(1) Kev Tiv Thaiv Kev Yaig: Tiv taus cov khoom me me hauv cov tshuaj txhaj tshuaj thee, cov tshuab xuab zeb, lossis cov roj av uas tsis muaj kev hloov pauv vim hnav.
(2) Kev Ciaj Sia Thaum Muaj Kub: Hloov pauv sai sai ntawm qhov kub thiab txias heev (piv txwv li kev txhaj roj hauv cov cub tawg hlau) yam tsis muaj kev tawg, ua tsaug rau SiC qhov kev nthuav dav thermal qis.
(3) Kev Tsis Muaj Tshuaj Lom Zem: Tiv taus xeb los ntawm cov tshuaj tsuag acidic / alkaline, cov ntsev molten, lossis cov nplaim oxidizing, kom ntseeg tau tias cov qauv orifice sib xws.
2. Kev Tswj Xyuas Kev Nqus Dej Zoo Rau Cov Txheej Txheem Tseem Ceeb
Hauv cov ntawv thov uas xav tau qhov tseeb ntawm qib micron, SiC nozzles muab kev ntseeg siab tsis sib xws:
(1) Qhov Orifice Geometry Ruaj Khoov: Tswj cov nqi ntws thiab cov qauv tsuag kom meej txawm tias tom qab raug rau 1500 ° C + ib puag ncig ntev, tsis zoo li cov hlau uas warp lossis ceramics uas lwj.
(2) Txo Kev Txhaws: Qhov chaw du thiab du ua rau cov khoom siv tsis sib sau ua ke hauv cov roj txhaj tshuaj lossis cov tshuaj tsuag.
(3) Kev Tiv Thaiv Siab Siab: Tiv taus cov hydraulic siab tshaj 500 MPa, zoo tagnrho rau kev txiav dej lossis kev tsav dav hlau.
3. Pab kom muaj kev kub hnyiab zoo
SiC nozzles yog qhov tseem ceeb hauv kev ua kom zoo dua cov tshuab hluav taws xob uas siv zog ntau:
(1) Kev Ruaj Ntseg Hluav Taws: Kev tsim qauv tiv taus cua sov ua kom muaj kev sib xyaw roj-cua hauv cov roj turbines lossis cov hlawv hluav taws xob, txo cov kub thiab NOx emissions.
(2) Kev Hloov Pauv Roj: Sib xws nrog hydrogen, biofuels, lossis roj hnyav, txhawb kev hloov mus rau cov chaw muaj zog ruaj khov.
(3) Kev Ua Haujlwm Zoo: Txo qhov poob cua sov los ntawm phab ntsa vim SiC lub zog ua kom sov siab, txhim kho kev ua haujlwm ntawm chav hlawv kom zoo txog li 15%.
Shandong Zhongpeng Special Ceramics Co., Ltd yog ib qho ntawm cov khoom siv tshiab silicon carbide ceramic loj tshaj plaws hauv Suav teb. SiC technical ceramic: Moh qhov nyuaj yog 9 (New Moh qhov nyuaj yog 13), nrog kev tiv thaiv zoo heev rau kev yaig thiab xeb, kev puas tsuaj zoo heev - kev tiv thaiv thiab kev tiv thaiv oxidation. SiC cov khoom lub neej kev pabcuam yog 4 txog 5 zaug ntev dua li 92% alumina khoom. MOR ntawm RBSiC yog 5 txog 7 zaug ntawm SNBSC, nws tuaj yeem siv rau cov duab nyuaj dua. Cov txheej txheem hais nqe yog ceev, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob rau tsis muaj leej twg. Peb ib txwm mob siab rau kev sib tw peb lub hom phiaj thiab muab peb lub siab rov qab rau lub zej zog.
