Ama-nozzle e-Silicon carbide (SiC) Burner

Ezinqubweni zokushisa okuphezulu lapho ukulawulwa koketshezi, ukumelana nokuguguleka komhlabathi, kanye nokuqina kokushisa kubalulekile,ama-nozzle e-silicon carbide (SiC)Ivelele njengesimangaliso sobunjiniyela. Ngokungafani nama-nozzle ajwayelekile e-ceramic noma ensimbi, izakhiwo ezihlukile ze-SiC zibhekana nezinselele ezinhlelweni zokusha, ukuqhutshwa, kanye nokufuthwa kwezimboni. Lesi sihloko sihlola ukuthi kungani izimboni ziya ngokuya zisebenzisa ama-nozzle e-SiC ukuze ziguqule ukusebenza kwezicelo ezidinga kakhulu.

1. Yenzelwe Izindawo Ezinoketshezi Olukhulu

Ama-nozzle e-SiC asebenza kahle kakhulu ekuphatheni isivinini esiphezulu, uketshezi kanye namagesi okushisa okuphezulu:

（1）Ukumelana Nokuguguleka: Ukumelana nezinhlayiya ezihudulayo kuma-injector amalahle, izinhlelo zokuqhumisa isihlabathi, noma ama-rocket propellants ngaphandle kokuguqulwa okubangelwa ukuguguleka.

（2）Ukusinda Kokushaqeka Kokushisa: Ijikeleza ngokushesha phakathi kwamazinga okushisa aphezulu (isb. ukujova uphethiloli ezithandweni zensimbi) ngaphandle kokuqhekeka, ngenxa yokwanda okuphansi kokushisa kwe-SiC.

（3）Ukungabi Namandla Kwamakhemikhali: Melana nokugqwala okuvela ezifuthweni ze-acidic/alkaline, usawoti oncibilikisiwe, noma amalangabi e-oxidizing, okuqinisekisa ukuthi i-orifice geometry iyafana.

2. Ukulawula Ukugeleza Okunembile Kwezinqubo Ezibucayi

Ezinhlelweni zokusebenza ezifuna ukunemba kwezinga le-micron, ama-nozzle e-SiC aletha ukuthembeka okungenakuqhathaniswa:

（1）I-Stable Orifice Geometry: Gcina amazinga okugeleza anembile kanye namaphethini okufafaza ngisho nangemva kokuchayeka isikhathi eside ezindaweni ezishisa kakhulu eziyi-1500°C+, ngokungafani nezinsimbi ezigobile noma ezenziwe ngobumba eziwohlokayo.

（2）Ukuvalwa Okuncishisiwe: Ukuphela kobuso obubushelelezi kakhulu kunciphisa ukwakheka kwezinto ezisetshenziswayo kuma-injector kaphethiloli noma ezinhlelweni zokufafaza ngamakhemikhali.

（3）Ukubekezelela Ukucindezela Okuphezulu: Imelana nokucindezela kwamanzi okudlula i-500 MPa, ilungele ukusika i-waterjet noma ukuqhutshwa kwendiza.

3. Ukuvumela Ukushiswa Okusebenza Kakhulu

Ama-nozzle e-SiC abaluleke kakhulu ekwenzeni ngcono izinhlelo zokushisa ezisebenzisa amandla amaningi:

（1）Ukuqina Komlilo: Umklamo omelana nokushisa uqinisekisa ukuxubana komoya nophethiloli okufanayo kuma-turbine egesi noma ezishisi zezimboni, okunciphisa izindawo ezishisayo kanye nokukhishwa kwe-NOx.

（2）Ukuguquguquka Kwamafutha: Kuhambisana ne-hydrogen, ama-biofuel, noma amafutha asindayo, okusekela ukushintshela emithonjeni yamandla esimeme.

（3）Ukusebenza Kahle Kokushisa: Nciphisa ukulahleka kokushisa ezindongeni ngenxa yokushisa okuphezulu kwe-SiC, uthuthukise ukusebenza kahle kwegumbi lokusha ngamaphesenti afinyelela ku-15%.

I-Shandong Zhongpeng Special Ceramics Co., Ltd ingenye yezixazululo ezinkulu zezinto ezintsha ze-silicon carbide ceramic eShayina. I-SiC technical ceramic: Ubulukhuni bukaMoh buyi-9 (ubulukhuni bukaMoh obuyi-13), bunokumelana okuhle kakhulu nokuguguleka nokugqwala, ukumelana okuhle kakhulu - ukumelana nokugqwala kanye nokulwa nokubola. Impilo yesevisi yomkhiqizo we-SiC ide ngokuphindwe ka-4 kuya ku-5 kune-92% ye-alumina material. I-MOR ye-RBSiC iphindwe ka-5 kuya ku-7 kune-SNBSC, ingasetshenziswa ezimweni eziyinkimbinkimbi kakhulu. Inqubo yokucaphuna iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ayilingani. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisela izinhliziyo zethu emphakathini.
