I ke kaʻina hana palekana kaiapuni o ka hana ʻoihana, ʻo ka desulfurization kahi hana koʻikoʻi i ka mālama ʻana i ka maʻemaʻe o ka lewa, a ʻo ka nozzle, ma ke ʻano he "mea hoʻokō koʻikoʻi" o ka ʻōnaehana desulfurization, e hoʻoholo pololei i ka pono o ka desulfurization a me ke ola o nā lako e pili ana i kāna hana. Ma waena o nā mea nozzle he nui,silicon carbide (SiC)ua lilo mālie i mea makemake ʻia ma ke kahua o ka desulfurization ʻoihana ma muli o kona mau pono hana kūikawā, a ua lilo i mea kōkua ikaika no nā ʻoihana e hoʻokō ai i ka pono kiʻekiʻe a me ka palekana o ke kaiapuni.
Malia paha ʻaʻole i kamaʻāina ka nui o ka poʻe me ka silicon carbide. I ka ʻōlelo maʻalahi, he mea metala ʻole inorganic i hana ʻia i hana ʻia e hoʻohui i ke kūpaʻa wela kiʻekiʻe o nā keramika me nā waiwai ikaika kiʻekiʻe o nā metala, e like me ke "koa paʻa" i hana ʻia no nā ʻano ʻoihana ʻino. Hoʻohana piha ka nozzle desulfurization i hana ʻia me ka silicon carbide i nā pono o kēia mea.
ʻO ka mea mua, ʻo ke kūpaʻa ikaika i ka pala ka mea nui o nā nozzles desulfurization silicon carbide. I ke kaʻina hana o ka desulfurization ʻoihana, ʻo nā desulfurizers ka hapa nui he media corrosive kiʻekiʻe 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 pala a me ka leakage. ʻAʻole wale kēia e pili i ka hopena desulfurization, akā pono nō hoʻi e hoʻololi pinepine, e hoʻonui ana i ke kumukūʻai o ka ʻoihana. Loaʻa i ka mea Silicon carbide ke kūpaʻa kemika maikaʻi loa a hiki ke pale aku i ka erosion o nā waikawa ikaika a me nā alkalis. ʻOiai i nā wahi corrosive wela kiʻekiʻe lōʻihi, hiki iā ia ke mālama i ka pono o ke kūkulu ʻana, e hoʻolōʻihi nui ana i ke ola lawelawe o nā nozzles a hoʻemi i ka pinepine o ka mālama ʻana i nā lako.
ʻO ka lua, ʻo kona kūpaʻa wela kiʻekiʻe maikaʻi loa e kūpono ia no nā ʻano hana paʻakikī like ʻole. ʻO ka mahana o ke kinoea flue i hoʻokuʻu ʻia mai nā paila ʻoihana, nā umu a me nā lako ʻē aʻe he kiʻekiʻe pinepine ia, a ʻo nā nozzles i hana ʻia me nā mea maʻamau e maʻalahi i ka deformation a me ka ʻelemakule ma lalo o ke kaiapuni wela kiʻekiʻe, e hopena ana i ka hopena pīpī maikaʻi ʻole a me ka hoʻemi ʻana i ka pono desulfurization. Loaʻa iā Silicon carbide ke kūpaʻa wela kiʻekiʻe maikaʻi loa. Hiki iā ia ke hana paʻa i loko o 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 o ka mahana, i mea e hōʻoia ai he like a palupalu ka pīpī, i hiki i ka desulfurizer ke hoʻopili piha me ke kinoea flue a hoʻomaikaʻi i ka pono desulfurization.
Eia kekahi, ʻaʻole pono e hoʻohaʻahaʻa ʻia ke kūpaʻa o ka mea silicon carbide. Ke holo nei ka ʻōnaehana desulfurization, hiki ke loaʻa kahi liʻiliʻi o nā ʻāpana paʻa i loko o ka desulfurizer, kahi e hoʻomau ai i ka ʻaʻahu ʻana ma ka paia o loko o ka nozzle. Ma hope o ka hoʻohana ʻana i ka nozzle maʻamau no ka manawa lōʻihi, e lilo ka puka i mea nui a e haunaele ka pīpī. He kiʻekiʻe loa ka paʻakikī o ka silicon carbide, a ʻoi aku ka kiʻekiʻe o kona kūpaʻa ʻana ma mua o nā metala a me nā keramika maʻamau. Hiki iā ia ke pale pono i ka ʻino a me ka ʻaʻahu ʻana o nā ʻāpana paʻa, mālama i ke kūpaʻa o ka puka nozzle, hōʻoia i ka lōʻihi o ka hopena pīpī, a pale i ka hōʻino ʻana o ka pono desulfurization i hoʻokumu ʻia e ka ʻaʻahu nozzle.
I nā koi kaiapuni e piʻi nei ka paʻakikī, ʻaʻole pono nā ʻoihana e hoʻokō i nā hoʻokuʻu maʻamau, akā e alualu pū i ka hana pono, paʻa, a me ke kumukūʻai haʻahaʻa o nā lako palekana kaiapuni. ʻO ka nozzle desulfurization silicon carbide, me kona mau pono koʻikoʻi ʻekolu o ke kūpaʻa ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa ʻana i ka ʻaʻahu, hoʻololi pono i nā koi koi o ka desulfurization ʻoihana. Hiki iā ia ke hoʻomaikaʻi i ka paʻa o ka hana o ka ʻōnaehana desulfurization a hōʻemi i nā kumukūʻai mālama lako, e lilo i koho kiʻekiʻe no ka hoʻonui ʻana i ke kaiapuni ʻoihana.
I ka wā e hiki mai ana, me ka holomua mau o ka ʻenehana hoʻomākaukau mea silicon carbide, e ʻoi aku ka laulā o kāna noi ma ke kahua o ka palekana o ke kaiapuni ʻoihana. A e hoʻomau ka nozzle desulfurization silicon carbide i ke kōkua ʻana i nā ʻoihana e hoʻokō i ka hana ʻōmaʻomaʻo me kāna hana paʻakikī, e hāʻawi ana i ka nui o ka palekana i ka lani polū a me nā ao keʻokeʻo.
