Na Umu Coke

ʻO kahi hiʻohiʻona o nā umu coke metallurgical a me ka nānā ʻana i nā kūlana hana:

ʻO nā umu Coke kahi ʻano mea wela me kahi ʻano paʻakikī e pono ai ka hana mau ʻana i ka wā lōʻihi. Hoʻomaʻamaʻa lākou i ka lanahu i 950-1050 ℃ ma o ka hoʻokaʻawale ʻana mai ka ea no ka distillation maloʻo e loaʻa ai ka coke a me nā huahana ʻē aʻe. Inā he coking maloʻo maloʻo a i ʻole coking pulu pulu, ma ke ʻano he mea hana no ka hana ʻana i ka coke wela ʻulaʻula, ʻo nā umu coke ka nui o nā keʻena coking, nā keʻena puhi, regenerators, furnace top, chutes, flues liʻiliʻi, a me kahi kumu, etc.

ʻO ke ʻano kumu hoʻokaʻawale wela o ka umu coke metallurgical a me kāna mau mea kōkua
Hoʻonohonoho ʻia ka ʻōnaehana insulation thermal mua o ka umu coke metallurgical a me kāna mau mea kōkua e like me nā brick refractory kiʻekiʻe + nā pōhaku insulation māmā + nā pōhaku lepo maʻamau (ʻo kekahi mau regenerators e hoʻohana i nā pōhaku diatomite + ʻano pōhaku lepo maʻamau ma lalo), a ʻokoʻa ka mānoanoa insulation me nā ʻano umu a me nā kūlana hana.

ʻO kēia ʻano hana insulation thermal ka nui o nā hemahema penei:

A. ʻO ka nui o ka thermal conductivity o nā mea hoʻoheheʻe wela e alakaʻi i ka hoʻokuʻu wela maikaʻi ʻole.
B. Pohō nui ma ka mālama ʻana i ka wela, ka hopena i ka pau ʻana o ka ikehu.
C. Loaʻa ka wela kiʻekiʻe loa ma ka pā o waho a me ke kaiapuni a puni i kahi ʻano hana ʻino.

ʻO nā mea e pono ai ke kino no nā mea hoʻolale kākoʻo o ka umu coke a me kāna mau mea kōkua: Me ka noʻonoʻo ʻana i ke kaʻina hana o ka umu ahi a me nā mea ʻē aʻe, ʻaʻole i ʻoi aku ka nui o nā mea hoʻopaʻa kākoʻo ma mua o 600kg/m3 i ko lākou puʻupuʻu leo, ʻo ka ikaika compressive i ka lumi wela ʻaʻole i emi iho ma mua o 0.3-0.4Mpa, a ʻaʻole pono ka hoʻololi ʻana o ka wela ma lalo o 0.0ºC.

ʻAʻole hiki i nā huahana fiber ceramic ke hoʻokō pono i nā koi i luna, akā loaʻa nō hoʻi nā pōmaikaʻi like ʻole i loaʻa ʻole i nā pōhaku insulation māmā.

Hiki iā lākou ke hoʻoponopono maikaʻi i nā pilikia i loaʻa i nā mea insulation thermal o ka hale hoʻoheheʻe kapuahi kumu: ka conductivity thermal nui, ka insulation thermal maikaʻi ʻole, ka nui o ka mālama ʻana i ka wela, ka pau ʻana o ka ikehu koʻikoʻi, ka wela ambient kiʻekiʻe, a me kahi ʻano hana paʻakikī. Ma muli o ka noiʻi piha ʻana i nā ʻano mea insulation thermal māmā a me nā hoʻokolohua kūpono a me nā hoʻokolohua, loaʻa nā huahana ceramic fiberboard i nā mea maikaʻi aʻe i hoʻohālikelike ʻia me nā brick insulation māmā.

A. Haʻahaʻa thermal conductivity a me ka maikaʻi mālama wela hopena. Ma ka mahana like, ʻo ka conductivity wela o nā papa fiberboard seramika ma kahi o hoʻokahi hapakolu wale nō o nā pōhaku lepo māmā maʻamau. Eia kekahi, i nā kūlana like, no ka hoʻokō ʻana i ka hopena insulation thermal like, hiki i ka hoʻohana ʻana i ka hale fiberboard ceramic ke hōʻemi i ka mānoanoa insulation thermal ma mua o 50 mm, e hōʻemi nui ana i ka nalowale o ka mālama ʻana i ka wela a me ka pau ʻana o ka ikehu.
ʻO B. ʻO nā huahana fiberboard Ceramic ka ikaika compressive kiʻekiʻe, hiki ke hoʻokō pono i nā koi o ka uhi ahi no ka ikaika compressive o nā pōhaku lepo insulation.
C. haʻahaʻa laina laina ma lalo o nā wela kiʻekiʻe; pale wela kiʻekiʻe a me ke ola lawelawe lōʻihi.
D. liʻiliʻi leo haʻahaʻa, hiki ke hoʻohaʻahaʻa pono i ke kaumaha o ke kino kapuahi.
E. maika'i ke kū'ē i ka ha'alulu wela a hiki ke kū i ke anu a me ka ho'ololi wela.
F. Nā nui geometric pololei, hana maʻalahi, ʻoki maʻalahi a hoʻokomo.
