He mea koʻikoʻi ka pale ʻana i ka corrosion o nā mea i nā ʻano he nui o ka hana ʻoihana. I kēia lā, e ʻimi mākou i ka hana koʻikoʻi onā huahana silika carbidee pili ana i ka pale ʻana i ka corrosion.
ʻO ka Silicon carbide kahi hui i haku ʻia me ka silika a me ke kalapona, nona kahi ʻano kristal kū hoʻokahi a me nā waiwai kemika. Mai kahi hiʻohiʻona microscopic, ua hoʻopaʻa paʻa ʻia nā ʻātoma silikona a me nā kalapona kalapona i loko o ka carbide silicon ma o nā mea paʻa covalent, e hana ana i kahi ʻano lattice paʻa. Hāʻawi kēia i ka silicon carbide i ke kūpaʻa kemika maikaʻi a me ka hiki ke pale aku i ka corrosion mai nā mea kemika like ʻole, ʻo ia hoʻi ke kumu kumu o kona kūpaʻa ʻana.
I nā hiʻohiʻona ʻoihana he nui, ke kū nei nā mea hana i ka pilikia o ka corrosion. No ka laʻana, i loko o nā mea kanu wela, hoʻohua ka lanahu i ka nui o ka ʻeaea i loko o ka sulfur. ʻO nā kinoea ʻakika e like me ka sulfur dioxide i loko o kēia mau kinoea puhi e hana i nā mea ʻino e like me ka sulfurous acid a me ka sulfuric acid ke hoʻopili ʻia me ka wai. Inā maikaʻi ʻole ke kino o ka mea hana desulfurization, e hoʻopau koke ia, e pili ana i ka hana maʻamau a me ke ola lawelawe o nā mea hana.
Ma ke ʻano he mea nui i ka ʻōnaehana desulfurization, ʻoi aku ka paʻakikī o ka hana o ka nozzle desulfurization. ʻAʻole wale ia e kū i ka erosion o ke kinoea flue wela kiʻekiʻe, akā pono nō hoʻi e hui pū me nā desulfurizers corrosive e like me ka mortar pōhaku no ka manawa lōʻihi. I loko o kēia kaiapuni, hiki i nā nozzles i hana ʻia i nā mea maʻamau i ka corrosion, ʻaʻahu, blockage, a me nā pilikia ʻē aʻe, e alakaʻi ana i ka emi ʻana o ka desulfurization pono a me ke koi ʻana i ka hoʻololi pinepine ʻana i ka nozzle, hoʻonui i nā kumukūʻai mālama a me ka downtime.
Hōʻike nā huahana Silicon carbide i nā pono koʻikoʻi i loko o ia mau kaiapuni. ʻO kona pale ʻana i ka corrosion e hiki ai iā ia ke hana paʻa no ka manawa lōʻihi, e hōʻemi pono ana i nā hemahema i hoʻokumu ʻia e ka corrosion. ʻOiai inā e pili ana me nā desulfurizers acidic ikaika a i ʻole alkaline no ka manawa lōʻihi, ʻaʻole maʻalahi ka palaka a me ka pōʻino o ka silicon carbide desulfurization nozzle, e hōʻoia ana i ka hana kūpono o ka ʻōnaehana desulfurization. Ma waho aʻe o ka pale ʻana i ka corrosion, ʻoi aku ka paʻakikī o ka silicon carbide, ka ikaika kiʻekiʻe, a me ke kūpaʻa maikaʻi. ʻO kēia mau hiʻohiʻona e hiki ai i ka silicon carbide desulfurization nozzle ke mālama i ka hana maikaʻi ʻoiai ke alo o ke kinoea flue kiʻekiʻe a me ka erosion particle paʻa, e hoʻolōʻihi loa i ke ola lawelawe o ka nozzle.
ʻO nā huahana Silicon carbide ka mea hiki ʻole ke hoʻololi ʻia i ke kahua o ka desulfurization nozzles ma muli o kā lākou kūpaʻa corrosion maikaʻi loa, e hāʻawi ana i nā hōʻoia ikaika no ka hana kūpono a paʻa o ka hana ʻoihana. Me ka hoʻomau mau ʻana o ka ʻenehana, e hoʻomau nā mea silicon carbide e hōʻike i ko lākou waiwai kūʻokoʻa i nā kula hou aʻe i ka wā e hiki mai ana, e hoʻokomo i ka ikaika hou i ka hoʻomohala ʻoihana.
