1. Corrosion Kuj
FGD NozZlesKev khiav lag luam nyob rau hauv lub corrosive ib puag ncig muaj sulguride, chlorides, thiab lwm yam tshuaj lom neeg. Silicon carbide (Sic) cov lus qhia txog kev tshwj xeeb corrosion corrosion nrog tsawg dua 0.1% kev daws teeb meem hauv PH 1-14 (rau ASTM C863 kuaj). Piv rau stainless hlau (pren 18-25) thiab nickel alloys (pren 30-40), sic tswjfwm kev ncaj ncees txawm tias nyob rau hauv cov accortrated acids ntawm ntug dej kub.
2. High-kub ruaj khov
Kev khiav hauj lwm kub nyob rau hauv ntub dej nyab cov roj desulfurization tshuab uas feem ntau 60-80 ° C nrog spikes tshaj 120 ° C. Cov leeg ua rau lub zog ntawm cov tshuab hluav taws xob 85% ntawm nws chav-kub ntawm 1400 ° C, Outperforming Alumina Ceramics (poob C) thiab cov hlau kub tawm. Nws cov thermal conductivity (120 w / map K. my kaph) ua rau muaj kev cuam tshuam kub dissipation, tiv thaiv kev cuam tshuam thermal kev ntxhov siab.
3. Coj tsis kam
Nrog lub vickers hardness ntawm 28 GPA thiab BPAs Kev nyuaj ntawm 4.6 mpa ¹ / ², sic kev nthuav tawm cov qib siab tsis kam tawm tsam ya tshauv (mohs 5-7). Kev ntsuam xyuas cov teb qhia sic Nozzles hnav tau zoo li 20,000 teev, piv rau 30-40% hnav hauv alumina nozzles thiab ua tiav tsis ua hauj lwm ntawm polymer-coated cov hlau tsis pub dhau 8,000 teev.
4. Flow Cwj Pwm
Qhov tsis-ntub dej ntawm cov tshuaj tiv thaiv-kev sib tsoo sic (hu rau kaum & 100 °) ua kom zoo nrog CV qhov tseem ceeb <5%. Nws cov ultra-du nto (ra 0.2-0.4μm) txo qis rau cov hlau no, thaum muaj kev tswj hwm ruaj khov (± 1%) dhau lub sijhawm ntev.
5. Txij Nkawm Yooj Yim
Sic cov tshuaj hnyuv tshuaj lom zem tso cai rau kev ua kom nruj nrog cov hau kev ua kom huv nrog:
- Dav hlau dej siab (txog li 250 bar)
- Ultrasonic tu nrog alkaline cov kev daws teeb meem
- Chav kom tsis muaj menyuam ntawm 150 ° C
Yog tsis muaj kev pheej hmoo ntawm kev ua kom muaj nyob rau hauv polymer-lined lossis coated hlau nozzles.
6. Lub neej muaj kev lag luam
Thaum lub sij hawm pib tus nqi rau sic nozzles yog 2-3 siab dua tus qauv 316L stainless hlau, lawv 8-3 xyoos Tag nrho cov nuj nqis cov nqi qhia txog 40-60% txuag tau tshaj 10-xyoo lub sijhawm, nrog xoom downtime rau hauv-situ kho vaj tse.
7. Ib puag ncig compatibilibility
Sic qhia cov kev ua tsis tau zoo hauv huab cua:
- ntsev txau tiv thaiv: 0% hloov pauv tom qab 5000hr Astm B117 Kuaj
- Acid Wew Taw tes ua haujlwm: withstands 160 ° C h2o4 vapors
- Thermal poob siab kuj: ciaj sia 1000 ° C → 25 ° C Quencel ncig mus
8. Cov Khoom Siv Hluav Taws Xob
Lub kev sib cav Atomic qauv ntawm cov nqaij uas tsis yog-reactive nto nrog ntsuas tus nqi 80% qis dua cov hlau sib txawv. Cov kev tshawb fawb crystallogries qhia pom tias daim calcite thiab gypsum tso nyiaj (adhesion
Kev Kawg
Silicon carbide tej hub tawm raws li qhov kev xaiv zoo tshaj plaws xaiv rau FGD nozzles los ntawm kev ntsuam xyuas ua tau zoo:
- 10 × ntev kev pab lub neej dua li yog lwm txoj kev xaiv
- 92% txo qis hauv kev saib xyuas tsis tau
- 35% txhim kho hauv SO2 tshem tawm kev ua tau zoo los ntawm cov qauv tsuag tshuaj
- Kev ua raws li EPA 40 CFR Tshooj 63 tus qauv emissions
Nrog kev nce qib kev paub zoo li kua-theem Sintering thiab CVD txheej, tom ntej no ua tiav sub-micron geometries yav dhau los tsis muaj nyob hauv Ceramics. Qhov kev hloov thev naus laus zis no silicon carbide raws li cov khoom ntawm kev xaiv rau tom ntej-tiam nrog flue roj tu tshuab.
