Xa iinjineli zezityalo zicacisa imilomo ye-denitrification ye-SCR okanye iinkqubo ze-SNCR, azithengi i-hardware-zigcina inkqubo yokuqhubeka. Ukusilela kombhobho omnye kunokubangela ukutyibilika kweammonia, HAYIx ukwaphulwa kokuthotyelwa, okanye ukuvalwa okungacwangciswanga okuxabisa i-$50,000+ ngeyure. Yiyo loo nto amaqela okuthengwa kwempahla ethengiweyo edlula abathengisi bamayeza enziwe afana nalawo enziwe ngabenzi kwaye aye ngqo ku denitrification umbhobho wemveliso ngoqeqesho oluqinisekisiweyo lwe-metallurgical-hayi nje isakhono somatshini.
IiNozzle zeCobalt Alloy “Azingoomatshini nje”—zenziwe ngobuNjineli beMetallurgical
Siye sabona ukungaphumeleli okuthathu okuqhelekileyo kwimibhobho ye-denitrification esetyenzisiweyo kwintsimi: ukuqhekeka kwe-thermal emva kweeyure zokusebenza ze-4,000, ukukhukuliseka kwi-orifice lip ngaphakathi kweenyanga ezi-6, kunye nokukhukuliseka kwe-dimensional ngexesha lokuhamba ngebhayisikile ephindaphindiweyo. Zonke zibuyela emva kunobangela omnye—ukungahambelani kwezinto, kungekhona isiphene soyilo. Iintsimbi ezisemgangathweni ezingenastainless (316L, 2205) zithambe ngaphezu kwe650°C. Irhasi ye-inlet flue flue kwizibane zesamente okanye izibhoyila zokulahla inkunkuma ukuya ku-eneji zihlala zibetha kuma-850–1,100°C. Yingakho i-AMS 5387 i-cobalt alloy ayikhethi-ayinakuxoxisana.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke ingxubevange yomlomo we-cobalt iqala nge-ingot eqinisekisiweyo ye-T800-grade, iphathwe ubushushu nge-AMS 2750E nganye, emva koko yenziwe ngomatshini kumaziko e-CNC e-5 kunye nembuyekezo yexesha lokwenene lobushushu. “Asiyongezi” ubulukhuni-siyabugcina. Imilomo yethu ibamba ±0.015 mm yokunyamezela kwii-engile zokutshiza ezibaluleke kakhulu nasemva kweeyure ezingama-12,000 kuma-920°C. Ayisiyo idatha yelebhu. Leyo yidatha yentsimi evela kwizityalo ezintathu zaseMntla Melika eziqhuba ukusukela kwi-Q3 ngo-2022.
Izahluli eziphambili azikho kwiincwadana-zikulawulo lwenkqubo:
- Ukulandeleka kwemathiriyeli ekrwada ukuya kwibhetshi enyibilikayo kunye nengxelo yespectrographic
- Kwinkqubo yokuqinisekiswa kwe-CMM kwiindawo ezintathu ze-thermal (njengoko-omatshini, emva kokushisa-ukuphatha, ukugqiba ukugqiba)
- Uvavanyo lokuhamba komsebenzi kwi-120% yoxinzelelo olulinganisiweyo usebenzisa iimitha ze-Doppler ze-ultrasonic calibrated
- Akukho zilophu zokuphinda zisebenze-isivuno sokuqala sidlula i-98.7% ye-AMS 5387 geometries
Kutheni udibaniso oluthe nkqo lubetha "Okugqwesileyo kwiKlasi" kwiNkontraki engaphantsi
Abanye ababoneleli bangaphandle bakhupha, besebenza, kunye nokugqiba ukwahlula abathengisi. Oko kudala amanqaku amathathu e-handoff-kunye namathuba amathathu e-microstructural compromise. Ukungalungelelani komda wokudla okuziinkozo phakathi kolwakhiwo lwesamente kunye nomphezulu owenziwe ngoomatshini? Khangela. Uxinzelelo olushiyekileyo olusuka kukuphola okungalinganiyo kubo bonke abathengisi? Iqinisekisiwe. Ukungangqinelani kokugqiba komphezulu okuchaphazela ukwaphuka kwamathontsi? Kulindelwe.
Singabanikazi bekhonkco elipheleleyo: utyalo-mali lwemilomo ye-cobalt ekufutshane-netha, ukujika okuchanekileyo kwe-CNC kunye nokusila kwi-alloys eqinile, unyango lobushushu bevacuum, kunye ne-electropolished yangaphakathi bores. Oku akukho lula-yi-physics. Xa umatshini ngqo kwi-controlled-grain cast substrate, ugcina amandla olwalathiso. Xa unyango lobushushu lulandela ukucwangciswa kwe-machining-kungekhona ngaphambi kwayo-ususa iimpazamo zokulungelelanisa ezibangelwa ukuphambuka kwiipateni ezininzi ze-orifice.
Imizimba yethu yentsimbi ephoswe ngesanti idityaniswa ngokungenamthungo kunye neengcebiso zokutshiza ingxubevange ye-cobalt ngokufaka uphazamiseko lokubrawuza, hayi ukudityaniswa komsonto. Ngoba? Ngenxa yokuba ukwanda kwe-thermal ukungalingani phakathi kwe-304SS yomzimba kunye ne-Stellite 6 tip kubangela ukudinwa ngokubambisana kwi-3-5 Hz i-vibration frequencies eziqhelekileyo kwi-bhoiler ducts. Siyayicombulula loo nto phambi kokuba umzobo ugqitywe.
Isiko asifani noKunyelisa-Lulungelelwaniso oluchanekileyo
“Isiko” lithetha izinto ezahlukeneyo kubathengi abohlukeneyo. Kwabanye, itshintsha isandi somsonto. Kuthi, iphinda ihlengahlengise yonke iprofayile eguquguqukayo yolwelo ukuze ihambelane neprofayile yakho yesantya segesi yeflue, ukulayishwa kwamasuntswana, kunye nethagethi yokusasazwa kwe-ammonia. Sihambise imilomo ene-asymmetric orifice arrays ye-asymmetric orifice arrays ye-cross-duct injection, iicones ezifakwe kwi-tapered inlet zones zesantya esisezantsi, kunye nemizimba yezinto ezimbini apho kuphela indawo yokutshiza ibona i-cobalt-ukunciphisa iindleko ngaphandle kokuncama ubomi.
Imiqobo yokwenyani yehlabathi iqhuba ubunjineli bethu:
- Udinga uxwebhu oluqinisekisiweyo lwe-ISO 9001 kodwa lusebenza phantsi kwe-ASME BPVC iCandelo VIII Div. 2 Kwenziwe-sigximfiza umbhobho ngamnye ngenombolo yobushushu, ingxelo ye-NDE, kunye nelogi ye-PWHT
- Ifuna ukutshintshwa kwelifa le-Babcock & Wilcox SNCR imilomo ene-non-standard 1.25'-12 UNJ threads? Sibuyisela umva-injineli kwaye siqinisekisa ukuhamba komlinganiso ngokuchasene nesiseko se-OEM
- Ngaba kufuneka uphumelele uvavanyo lwesitshizi somntu wesithathu nge-ASTM B117 nganye yofakelo lwaselunxwemeni? Umphezulu wethu we-cobalt owenziwe nge-electropolished ufikelela kwiiyure ezingama-1,500 ukuya kumhlwa omhlophe
Asibuzi ukuba "Ufuna ntoni?" Siyabuza, “Kumele kuqhubeke ntoni oku—kwaye ixesha elingakanani?” Emva koko sakha kuloo nto, hayi iphepha lekhathalogu.
Ukuthembeka kuqala kwakudala ngaphambi kokuthunyelwa
A ethembekileyo denitrification umbhobho wemveliso ayipheli edokhini. Iqala ngophononongo lwe-GD&T-ukubamba iimpazamo zokupakisha kwii-callouts zokugxila ngaphambi kokuba kuqale isixhobo. Iyaqhubeka nokuqinisekiswa kovavanyo: imilomo emithathu evavanyiweyo kwisilingisi sakho segesi yombane (sithumela izilungiso zovavanyo ukuba ziyafuneka). Iphela ngokulandelwa kokuhanjiswa okubandakanya ii-certs eziphathekayo, iingxelo ze-CMM, kunye ne-QR-linked digital twin ebonisa yonke imilinganiselo elinganisiweyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iinqanawa kumazwe angama-27 ngenxa yokuba ukuthembeka kudibanisa. Omnye umthengi eJamani waodola imilomo ye-142 ukuze athenge amalahle. Emva kweenyanga ze-18, zero replacements. Iqela labo logcino liye layeka ukucwangcisa ukuhlolwa kwemibhobho yonyaka-kwaye laphinda lahambisa ezo yure zabasebenzi kuhlaziyo oluqikelelweyo. Leyo yi-ROI yoqeqesho lwe-metallurgical.
Ukuba iodolo yakho elandelayo ye-denitrification ye-nozzle ixhomekeke kwixesha-hayi nje ixabiso leyunithi-ufuna ngaphezulu komthengisi. Ufuna iqabane eliphatha i-cobalt njengento ephilayo, kungekhona into yokuthengisa. Qala ngokulandeleka kwezinto. Banga i-thermal-state metrology. Ifuna ukuqinisekiswa kokuhamba okusebenzayo. Emva koko ukhethe ngokufanelekileyo.
