Ma ke kaʻina hana hoʻomalu kaiapuni o ka hana ʻoihana, ʻo ka desulfurization kahi kī nui i ka mālama ʻana i ka maʻemaʻe o ka lewa, a ʻo ka nozzle, ʻo ia ka "hoʻokō kumu" o ka ʻōnaehana desulfurization, e hoʻoholo pololei i ka desulfurization pono a me nā lako ola ma muli o kāna hana. Ma waena o nā mea nozzle he nui,kalapona kalapona (SiC)ua lilo mālie i mea i makemake nui ʻia ma ke kahua o ka desulfurization ʻoihana ma muli o kāna mau pono hana kūʻokoʻa, a ua lilo ia i mea kōkua ikaika no nā ʻoihana e hoʻokō i ka hana kiʻekiʻe a me ka palekana o ke kaiapuni.
Nui paha ka poʻe i kamaʻāina ʻole i ka carbide silika. ʻO ka waiho wale ʻana, he mea hoʻoheheʻe ʻia ʻole ia i hoʻohui ʻia i ke kūpaʻa wela kiʻekiʻe o nā seramika me nā waiwai ikaika kiʻekiʻe o nā metala, e like me ke "koa lōʻihi" i hoʻohālikelike ʻia no nā kaiapuni ʻoihana paʻakikī. ʻO ka nozzle desulfurization i hana ʻia me ka silicon carbide e hoʻohana piha i nā pono o kēia mea.
ʻO ka mea mua, ʻo ke kūpaʻa corrosion ikaika ka mea nui o ka silicon carbide desulfurization nozzles. I ke kaʻina hana o ka desulfurization ʻoihana, ʻo nā desulfurizers ka hapa nui o nā media corrosive me ka acidity ikaika a me ka alkalinity. Hoʻokomo maʻalahi ʻia nā nozzles metala maʻamau i loko o lākou no ka manawa lōʻihi, hiki ke alakaʻi i ka corrosion a me ka leakage. ʻAʻole pili wale kēia i ka hopena desulfurization, akā pono pū kekahi e hoʻololi pinepine, e hoʻonui ana i ke kumukūʻai o ka ʻoihana. ʻO ka mea silikoni carbide ponoʻī he kūpaʻa kemika maikaʻi loa a hiki ke pale aku i ka hoʻoneʻe ʻana o nā waikawa ikaika a me nā alkalis. ʻOiai i loko o nā kaiapuni corrosive wela kiʻekiʻe, hiki iā ia ke mālama i ka kūpaʻa o ke kūkulu ʻana, hoʻonui nui i ke ola lawelawe o nā nozzles a me ka hōʻemi ʻana i ke alapine mālama pono.
ʻO ka lua, ʻo kona kūpaʻa kiʻekiʻe kiʻekiʻe e kūpono i nā kūlana hana paʻakikī. He kiʻekiʻe loa ka mahana o ke kinoea flue i hoʻokuʻu ʻia mai nā paila ʻoihana, kiln a me nā mea hana ʻē aʻe, a ʻo nā nozzles i hana ʻia i nā mea maʻamau e maʻalahi i ka deformation a me ka ʻelemakule ma lalo o ke kiʻekiʻe o ka mahana wela, e hopena i ka hopena maikaʻi ʻole a me ka hoʻemi ʻana o ka desulfurization. ʻO ka silikon carbide maikaʻi loa ka pale wela kiʻekiʻe. Hiki iā ia ke hana paʻa i ke kinoea flue wela kiʻekiʻe o nā haneli degere Celsius, a ʻaʻole e hoʻopilikia i ka hoʻolālā a me ka hana ma muli o nā loli wela, i mea e hōʻoia ai i ka ʻaʻahu a me ka maʻalahi, i hiki ai i ka desulfurizer ke hoʻopili piha me ke kinoea a hoʻomaikaʻi i ka desulfurization pono.
Eia kekahi, ʻaʻole pono e hoʻohaʻahaʻa ʻia ka pale ʻana o nā mea silika carbide. Ke holo nei ka ʻōnaehana desulfurization, hiki ke loaʻa kahi liʻiliʻi o nā ʻāpana paʻa i loko o ka desulfurizer, kahi e hoʻokau mau ai i ka paia o loko o ka nozzle. Ma hope o ka hoʻohana ʻia ʻana o ka nozzle maʻamau no ka manawa lōʻihi, e ʻoi aku ka nui o ka aperture a e hoʻopilikia ʻia ka spray. He kiʻekiʻe loa ka paʻakikī o ka silicon carbide, a ʻoi aku ka kiʻekiʻe o kona pale ʻana ma mua o nā metala a me nā seramika maʻamau. Hiki iā ia ke pale pono i ka erosion a me ka ʻaʻahu o nā ʻāpana paʻa, mālama i ka paʻa o ka nozzle aperture, e hōʻoia i ka lōʻihi o ka lōʻihi o ka hopena spray, a pale i ka hoʻohaʻahaʻa ʻana o ka desulfurization maikaʻi ma muli o ka lole nozzle.
I nā koi kaiapuni e piʻi aʻe nei, ʻaʻole pono nā ʻoihana e hoʻokō i nā hoʻokuʻu maʻamau, akā e ʻimi pū i ka hana kūpono, kūpaʻa, a me ka haʻahaʻa haʻahaʻa o nā lako pale kaiapuni. ʻO ka silicon carbide desulfurization nozzle, me kāna mau mea pono ʻekolu o ka pale ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa ʻana o ka lole, kūpono loa i nā koi koi o ka desulfurization ʻoihana. Hiki iā ia ke hoʻomaikaʻi i ka hana paʻa o ka ʻōnaehana desulfurization a hōʻemi i nā kumukūʻai mālama pono, lilo i koho kiʻekiʻe no ka hoʻomaikaʻi ʻana o ka ʻoihana.
I ka wā e hiki mai ana, me ka hoʻomau mau ʻana o ka ʻenehana hoʻomākaukau ʻana i ka silicon carbide, ʻoi aku ka nui o kāna noi ʻana ma ke kahua o ka mālama ʻana i ke kaiapuni. A e hoʻomau ka silicon carbide desulfurization nozzle e kōkua i nā ʻoihana e hoʻokō i ka hana ʻōmaʻomaʻo me kāna hana paʻakikī, e hāʻawi nui i ka mālama ʻana i ka lani uliuli a me nā ao keʻokeʻo.
