Silicon carbide (SiC) Burner nozzles
M'njira zotentha kwambiri pomwe kuwongolera kwamadzimadzi, kukana kukokoloka, komanso kukhazikika kwamafuta ndikofunikira,silicon carbide (SiC) nozzleskuwonekera ngati chodabwitsa cha uinjiniya. Mosiyana ndi ma generic ceramic nozzles kapena zitsulo zachitsulo, mawonekedwe apadera a SiC amalimbana ndi zovuta pakuyatsa, kuyendetsa, ndi kupopera mbewu kwa mafakitale. Nkhaniyi ikuwonetsa chifukwa chake mafakitale akuchulukirachulukira kugwiritsa ntchito ma nozzles a SiC kuti asinthe magwiridwe antchito pazovuta kwambiri.
1. Zapangidwira Malo Opanda Madzi Kwambiri
Ma nozzles a SiC amapambana pakuwongolera kuthamanga kwambiri, zamadzimadzi zotentha kwambiri komanso mpweya:
(1).
(2) Kupulumuka Kutentha Kwambiri: Kuthamanga kwachangu pakati pa kutentha kwambiri (monga jekeseni wamafuta m'ng'anjo zazitsulo) popanda kusweka, chifukwa cha kuwonjezeka kwa kutentha kwa SiC.
(3) Kusakhazikika kwa Chemical: Pewani dzimbiri kuchokera ku zopopera za acidic/alkaline, mchere wosungunuka, kapena malawi oyaka oxidizing, kuonetsetsa kuti geometry ya orifice ikufanana.
2. Precision Flow Control for Critical Processes
M'mapulogalamu omwe amafunikira kulondola kwa ma micron, ma nozzles a SiC amapereka kudalirika kosayerekezeka:
(1) Stable Orifice Geometry: Pitirizani kuyenda bwino komanso mawonekedwe opopera ngakhale mutakumana kwa nthawi yayitali ndi 1500 ° C+, mosiyana ndi zitsulo zomwe zimapindika kapena zoumba zomwe zimawonongeka.
(2) Kuchepetsa Kutsekeka: Kutsirizitsa kwapamwamba kwambiri kumachepetsa kuchulukana kwazinthu mu majekeseni amafuta kapena makina opopera mankhwala.
(3) Kulekerera Kwapamwamba Kwambiri: Kupirira kupanikizika kwa hydraulic kupitirira 500 MPa, yabwino kwa kudula kwamadzi kapena kuyendetsa ndege.
3. Kuthandizira Kuyaka Kwambiri Kwambiri
Ma nozzles a SiC ndi ofunikira kwambiri pakukhathamiritsa makina oyatsira mphamvu kwambiri:
(1) Kukhazikika kwa Lawi lamoto: Mapangidwe osagwira kutentha amatsimikizira kusakanikirana kwamafuta ndi mpweya m'ma turbines a gasi kapena zoyatsira zamafakitale, kuchepetsa malo otentha ndi mpweya wa NOx.
(2) Kusinthasintha kwa Mafuta: Kugwirizana ndi haidrojeni, biofuel, kapena mafuta olemera, kuthandizira kusintha kwa mphamvu zokhazikika.
(3) Kutentha Kwambiri: Chepetsani kutayika kwa kutentha kudzera m'makoma chifukwa cha kutentha kwa SiC, kupititsa patsogolo mphamvu ya chipinda choyaka ndi 15%.
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwamayankho akulu kwambiri a silicon carbide ceramic ku China. SiC ukadaulo wa ceramic: Kulimba kwa Moh ndi 9 (Kulimba kwa Moh Chatsopano ndi 13), kukana kwambiri kukokoloka ndi dzimbiri, abrasion yabwino - kukana ndi anti-oxidation. Moyo wautumiki wa SiC ndi 4 mpaka 5 nthawi yayitali kuposa 92% alumina. MOR ya RBSiC ndi 5 mpaka 7 nthawi ya SNBSC, itha kugwiritsidwa ntchito pazinthu zovuta kwambiri. Ndondomeko yobwereketsa ndi yofulumira, yobweretsera ndi monga momwe inalonjezedwa ndipo khalidweli ndi lachiwiri kwa wina aliyense. Nthawi zonse timalimbikira kutsutsa zolinga zathu ndikubwezeranso mitima yathu kwa anthu.
