Silicon carbide (SiC) Burner nozzles
Hauv cov txheej txheem kub kub uas tswj cov kua dej, yaig tsis kam, thiab thermal stability yog qhov tseem ceeb,silicon carbide (SiC) nozzlessawv tawm raws li engineering marvel. Tsis zoo li cov generic ceramic lossis hlau nozzles, SiC cov khoom tshwj xeeb daws cov teeb meem hauv kev sib tsoo, propulsion, thiab cov tshuab txau tshuab. Kab lus no tshawb txog vim li cas kev lag luam tau nce siv SiC nozzles los hloov pauv kev ua tau zoo hauv cov ntawv thov xav tau tshaj plaws.
1. Engineered rau Extreme Fluid Environments
SiC nozzles ua tau zoo hauv kev tswj cov kev tshaj tawm, kub-kub thiab roj:
(1) Erosion Resistance: Tiv thaiv cov khoom abrasive hauv coal slurry injectors, sandblasting systems, los yog foob pob ua ntxaij propellants yam tsis hnav-induced deformation.
(2) Thermal Shock Survival: Lub voj voog nrawm nrawm ntawm qhov kub thiab txias (xws li kev txhaj tshuaj roj hauv cov cub tawg metallurgical) yam tsis muaj qhov tawg, ua tsaug rau SiC qhov thermal expansion.
(3) Chemical Inertness: Tiv thaiv corrosion los ntawm acidic / alkaline sprays, molten ntsev, los yog oxidizing nplaim, kom ntseeg tau tias zoo ib yam orifice geometry.
2. Precision Flow Control rau cov txheej txheem tseem ceeb
Hauv cov ntawv thov thov qhov tseeb micron-theem, SiC nozzles xa cov kev ntseeg tsis sib haum:
(1) ruaj khov Orifice Geometry: Khaws cov nqi txaus thiab cov qauv tshuaj tsuag txawm tias tom qab lub sijhawm ntev mus rau 1500 ° C + ib puag ncig, tsis zoo li cov hlau uas warp lossis ceramics uas degrade.
(2) Txo Clogging: Ultra-nqus nto tiav txo cov khoom tsim hauv cov roj injectors lossis tshuaj tsuag tshuab.
(3) Siab siab kam rau ua: Nrog hydraulic siab tshaj 500 MPa, zoo tagnrho rau waterjet txiav los yog aerospace propulsion.
3. Ua kom muaj kev ua haujlwm siab combustion
SiC nozzles yog qhov tseem ceeb hauv kev txhim kho lub zog-intensive combustion systems:
(1) Nplaim Stability: Cov qauv tsim hluav taws xob tiv thaiv kom ntseeg tau tias cov roj cua sib xyaw ua ke hauv cov roj turbines lossis cov khoom siv hluav taws xob, txo cov hotspots thiab NOx emissions.
(2) Roj Flexibility: Tau tshaj hydrogen, biofuels, lossis hnyav roj, txhawb kev hloov mus rau qhov chaw muaj zog.
(3) Thermal Efficiency: Txo cov cua sov los ntawm cov phab ntsa vim SiC lub siab thermal conductivity, txhim kho combustion chamber efficiency txog li 15%.
Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd yog ib qho ntawm cov loj tshaj plaws silicon carbide ceramic cov khoom siv tshiab hauv Suav teb. SiC technical ceramic: Moh lub hardness yog 9 (New Moh's hardness yog 13), nrog zoo heev tiv taus yaig thiab corrosion, zoo heev abrasion - kuj thiab anti-oxidation. SiC khoom lub neej kev pab cuam yog 4 mus rau 5 zaug ntev dua 92% alumina khoom. MOR ntawm RBSiC yog 5 txog 7 npaug ntawm SNBSC, nws tuaj yeem siv rau cov duab ntau dua. Cov txheej txheem hais tau nrawm, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob. Peb ib txwm pheej sim sim peb lub hom phiaj thiab muab peb lub siab rov qab los rau zej zog.
