Uma onjiniyela bezitshalo becacisa imibhobho yokukhishwa kwe-denitrification yezinhlelo ze-SCR noma ze-SNCR, abathengi izingxenyekazi zekhompuyutha—bavikela ukuqhubeka kwenqubo. Ukwehluleka kombhobho owodwa kungadala ukushelela kwe-ammonia, CHAx ukwephulwa komthetho, noma ukuvalwa okungahleliwe kubiza u-$50,000+ ngehora. Yingakho amaqembu okuthenga edlula abahlinzeki abajwayelekile bese eqonda ngqo ku-a denitrification nozzle ifektri ngesiyalo esiqinisekisiwe se-metallurgical-hhayi nje ikhono lokwenza imishini.
I-Cobalt Alloy Nozzles “Ayiyona Nje Yomshini”—Akhiwe Ngensimbi
Sibone ukwehluleka okuthathu okujwayelekile emibhobolweni yokukhishwa kwe-denitrification esetshenziswe ensimini: ukuqhekeka okushisayo ngemva kwamahora okusebenza angu-4,000, ukuguguleka kodebe lwe-orifice phakathi nezinyanga ezingu-6, kanye nokukhukhuleka kobukhulu ngesikhathi sokuhamba ngebhayisikili elishisayo. Konke kulandelela emuva kumsuka owodwa—ukungafani kokubalulekile, hhayi iphutha lokuklama. Izinsimbi ezingenasici ezijwayelekile (316L, 2205) zithambe ngaphezu kuka-650°C. I-inlet flue gas eziko zikasimende noma kumabhoyela akhipha imfucuza kuya kumandla ngokuvamile ifinyelela ku-850–1,100°C. Kungakho i-AMS 5387 cobalt alloy ingeyona inketho—akuxoxiswana ngayo.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., wonke umbhobho wengxubevange ye-cobalt uqala ngengot yebanga le-T800 eqinisekisiwe, ephathwa ngokushisa nge-AMS 2750E ngayinye, bese ifakwa ngomshini ezikhungweni ze-CNC ze-5-axis ngesinxephezelo sesikhathi sangempela esishisayo. “Asingezi” ubulukhuni—siyabulondoloza. Imilomo yethu ibamba ukubekezelela okungu-±0.015 mm kuma-engeli abalulekile wokufutha ngisho nangemva kwamahora ayi-12,000 ku-920°C. Lokho akuyona idatha yelebhu. Leyo yidatha yasensimini evela ezitshalweni ezintathu ze-biomass zaseNyakatho Melika ezisebenza kusukela ngo-Q3 2022.
Izahlukanisi eziyinhloko azikho ezincwajaneni—zilawula inqubo:
- Ukulandeleka kwempahla eluhlaza kuze kube yinqwaba kanye nombiko we-spectrographic
- Ukuqinisekiswa okungaphakathi kwenqubo ye-CMM ezifundeni ezintathu ezishisayo (njengomshini, ukushisa kwangemuva, ukuqeda)
- Ukuhlolwa kokugeleza okusebenzayo ku-120% yengcindezi elinganiselwe kusetshenziswa amamitha e-Doppler e-ultrasonic alinganisiwe
- Awekho amalophu okusebenza kabusha—isivuno sokuqala sidlula u-98.7% kumajiyometri e-AMS 5387
Kungani Ukuhlanganiswa Okuqondile Kwehlula Inkontileka Engaphansi “Engcono Kakhulu Ekilasini”
Abanye abahlinzeki bakhipha imithombo yokusakaza, ukwenza imishini, nokuqedela ukuze bahlukanise abathengisi. Lokho kwakha amaphuzu amathathu e-handoff—kanye namathuba amathathu okuyekethisa kwesakhiwo esincane. Ukungalungi kahle komngcele wokudla okusanhlamvu phakathi kwesakhiwo esilingisi nendawo ewumshini? Hlola. Ingcindezi eyinsalela evela ekupholiseni okungalingani kubo bonke abathengisi? Kuqinisekisiwe. Ukungaguquguquki kokuphela kwendawo okuthinta ukuhlukana kwamaconsi? Kulindelwe.
Singabanikazi bamaketango aphelele: ukufakwa kwe-investment of close-net-shape cobalt nozzles, ukunemba ukujika kwe-CNC nokugaya kuma-alloys aqinile, ukwelapha ukushisa kwe-vacuum, kanye nezibhobo zangaphakathi ezipholishwe ngogesi. Lokhu akulula-kuyi-physics. Uma ufaka umshini ngokuqondile ku-controlled-grain cast substrate, ugcina amandla okuqondisa. Lapho ukwelashwa kokushisa kulandela umshini—hhayi ngaphambi kwakho—ususa amaphutha okuqondanisa abangelwa ukuhlanekezela kumaphethini ane-multi-orifice.
Imizimba yethu ye-sand-cast steel nozzle ihlanganisa ngaphandle komthungo namathiphu wokufufaza ingxubevange ye-cobalt ngokusebenzisa i-brazing-fit brazing, hhayi ukuhlanganiswa kwentambo. Kungani? Ngoba ukungezwani kokwanda okushisayo phakathi komzimba we-304SS kanye nethiphu ye-Stellite 6 kubangela ukukhathala okuhlangene kumaza okudlidliza angu-3–5 Hz okuvamile kumapayipi okubhayela. Sixazulula lokho ngaphambi kokuthi umdwebo uphothulwe.
Isiko Alifani Nokwehliswa—Ukuqondanisa Ngokunembayo
“Isiko” lisho izinto ezahlukene kubathengi abahlukene. Kwabanye, ishintsha iphimbo lentambo. Kithina, ihlela kabusha yonke iphrofayili eguquguqukayo yoketshezi ukuze ifane nephrofayili yakho yesivinini segesi ye-flue, ukulayishwa kwezinhlayiyana, kanye nethagethi yokusabalalisa i-ammonia. Silethe ama-nozzle anama-asymmetric orifice arrays omjovo owela umgudu, amakhoni okungenisa acijile wezindawo ezinesivinini esiphansi, kanye nemizimba yezinto ezimbili lapho kuphela indawo yesifutho ebona i-cobalt—ukunciphisa izindleko ngaphandle kokudela ukuphila.
Izingqinamba zomhlaba wangempela ziqhuba ubunjiniyela bethu:
- Udinga imibhalo eqinisekisiwe ye-ISO 9001 kodwa isebenza ngaphansi kwe-ASME BPVC Isigaba VIII Div. 2? Kwenziwe—sigxiviza i-nozzle ngayinye ngenombolo yokushisa, umbiko we-NDE, kanye nelogi ye-PWHT
- Idinga ukushintshwa kwamanozzle e-Babcock & Wilcox SNCR ayigugu anochungechunge olungajwayelekile lwe-1.25'-12 UNJ? Sihlehlisa unjiniyela futhi siqinisekise ama-flow coefficients ngokumelene nesisekelo se-OEM
- Ingabe kufanele uphumelele ukuhlolwa kwesifutho sikasawoti esivela eceleni nge-ASTM B117 ngayinye ekufakweni ogwini? Indawo yethu ye-cobalt eyenziwe nge-electropolished ifinyelela amahora angu-1,500 ukugqwala okumhlophe
Asibuzi ukuthi "Ufunani?" Siyabuza “Yini lena okufanele iqhubeke—futhi kuze kube nini?” Bese sakhela kuleso sici, hhayi ikhasi lekhathalogi.
Ukuthembeka Kuqala Kade Ngaphambi Kokuthunyelwa
A okuthembekile denitrification nozzle ifektri ayigcini esitokisini. Iqala ngokubuyekezwa kwe-GD&T—ukubamba amaphutha esitaki kuma-callouts we-concentricity ngaphambi kokuthi kuqale ukusebenza. Iyaqhubeka nokuqinisekisa okwenziwa umshayeli: imibhobho emithathu ehlolwe kusifanisi sakho sangempela segesi ye-flue (sithumela izinto zokuhlola uma kudingeka). Iphetha ngokulandelela ukulethwa okuhlanganisa izitifiketi zezinto ezibonakalayo, imibiko ye-CMM, newele ledijithali elixhunywe ku-QR elibonisa bonke ubukhulu obulinganisiwe.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ithumela emazweni angama-27 ngenxa yokuthi ukwethembeka kuhlanganisa. Elinye ikhasimende eJalimane la-oda imibhobho engu-142 ukuze lithole inzuzo yamalahle. Ngemuva kwezinyanga eziyi-18, ukushintshwa kuka-zero. Ithimba labo labalungisayo liyekile ukuhlela ukuhlolwa kwemibhobho yonyaka—futhi labeka kabusha lawo mahora omsebenzi ekuthuthukisweni kokuhlaziya okubikezelwayo. Leyo yi-ROI yesiyalo se-metallurgical.
Uma i-oda lakho elilandelayo le-denitrification lincike esikhathini—hhayi nje inani leyunithi—udinga okungaphezu komhlinzeki. Udinga umlingani ophatha i-cobalt njengento ephilayo, hhayi impahla. Qala ngokulandeleka kwezinto. Funa i-thermal-state metrology. Idinga ukuqinisekiswa kokugeleza kokusebenza. Bese ukhetha ngokufanele.
