Na kapuahi ano bele

Nānā nui:
Hoʻohana nui ʻia nā kapuahi ʻano bele no ka hoʻoheheʻe ʻana a me ka mālama wela, no laila, he mau umu wela like ʻole. Noho ka mahana ma waena o 650 a me 1100 ℃ ka hapa nui, a hoʻololi ia i ka manawa i kuhikuhi ʻia i ka ʻōnaehana hoʻomehana. Ma muli o ka hoʻouka ʻana o nā kapuahi ʻano bele, ʻelua ʻano ʻano: ka umu ʻano bele huinaha a me ka umu ahi ʻano bele poepoe. ʻO nā kumu wela o nā kapuahi ʻano bele ka nui o ke kinoea, a ukali ʻia e ka uila a me ka ʻaila māmā. ʻO ka mea maʻamau, ʻekolu ʻāpana o nā kapuahi ʻano bele: kahi uhi waho, kahi uhi i loko, a me kahi umu. Hoʻonoho pinepine ʻia ka mea puhi ahi ma ka uhi o waho i hoʻopaʻa ʻia me kahi papa wela, aʻo nā mea hana i waiho ʻia i loko o ka uhi o loko no ka hoʻomehana a me ka hoʻomaha.

He maikaʻi ka paʻa ʻana o ka ea i nā kapuahi ʻano bele, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ka hana wela kiʻekiʻe. Eia kekahi, ʻaʻole pono lākou i ka puka umu a i ʻole ka mea hoʻokiʻekiʻe a me nā ʻano mīkini hoʻoili ʻē aʻe, no laila e mālama lākou i nā kumukūʻai a hoʻohana nui ʻia i nā umu wela o nā mea hana.
ʻElua koʻikoʻi koʻikoʻi no nā mea hoʻoheheʻe kapuahi he māmā ke kaumaha a me ka ikaika o ka ikehu o nā uhi wela.

Nā pilikia maʻamau me ka refracto māmā maʻamaunā pōhaku lepo a i ʻole castable stʻO nā ructures e komo pū me:

1. ʻO nā mea refractory me ka umekaumaha kikoʻī nui (ʻo ka maʻamau maʻamau nā pōhaku kukui refractory i ka umekaumaha kikoʻī o 600KG / m3 a ʻoi aku; ʻo ka castable māmā he 1000 KG / m3 a ʻoi aʻe paha) e koi i ka ukana nui ma ke ʻano kila o ka uhi umu, no laila e hoʻonui ʻia ka hoʻohana ʻana i ka hale kila a me ka hoʻokomo ʻana i ke kūkulu ʻana i ka umu.

2. ʻO ka uhi waho nui e pili ana i ka hiki ke hāpai a me ka papahele papahele o nā hale hana hana.

3. Hoʻohana ʻia ka umu ahi ʻano bele ma nā ʻano wela like ʻole, a ʻo nā pōhaku kukui refractory a i ʻole nā ​​castable māmā i loaʻa i kahi wela kikoʻī kikoʻī nui, kahi kiʻekiʻe thermal conductivity, a me ka hoʻohana ʻana i ka ikehu.

Eia nō naʻe, he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa nā huahana CCEWOOL refractory fiber, mālama haʻahaʻa wela, a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻo ia ke kumu nui o kā lākou noi ākea i nā uhi wela. ʻO nā hiʻohiʻona penei:

1. He laulā wela o ka hana a me nā palapala noi like ʻole
Me ka hoʻomohala ʻana o ka CCEWOOL ceramic fiber production a me ka ʻenehana, ua loaʻa i nā huahana fiber ceramic CCEWOOL ka serialization a me ka hana. Ma ke ʻano o ka mahana, hiki i nā huahana ke hoʻokō i nā koi o nā mahana like ʻole mai 600 ℃ a 1500 ℃. Ma ke ʻano o ka morphology, ua hoʻomohala mālie nā huahana i nā ʻano hana kiʻekiʻe a i ʻole nā ​​huahana hana hohonu mai ka pulupulu kuʻuna, nā pākeke, nā huahana i manaʻo ʻia i nā modula fiber, nā papa, nā ʻāpana ʻano kūikawā, ka pepa, ka fiber textiles a pēlā aku. Hiki iā lākou ke hoʻokō piha i nā koi o nā kapuahi ʻoihana no nā huahana fiber ceramic i nā ʻoihana like ʻole.
2. Li'ili'i leo ha'aha'a:
ʻO ka nui o ka nui o nā huahana fiber ceramic ma ke ʻano he 96 ~ 160kg / m3, ʻo ia ka 1/3 o nā pōhaku māmā a me ka 1/5 o ka castable refractory māmā. No ka umu i hoʻolālā houʻia,ʻaʻole hiki i ka hoʻohanaʻana i nā huahana fiber ceramic ke hoʻopakele i ke kila wale nō, akā, e hana maʻalahi ka hoʻouka / weheʻana a me ka halihaliʻana, e hoʻoikaika i ka holomua i kaʻenehana umu ahi.
3. Liʻiliʻi wela wela a me ka wela:
Ke hoʻohālikelike ʻia me nā pōhaku lepo refractory a me nā pōhaku insulation, ʻoi aku ka haʻahaʻa o nā huahana fiber ceramic, ma kahi o 1/14-1/13 o nā pōhaku refractory a me 1/7-1/6 o nā pōhaku insulation. No ka intermittently opeʻia bele-type umu ahi, he nui nui o non-production-pili wahie hoʻohana hiki ke hoola.
4. Hana maʻalahi, manawa pōkole
No ka mea, he elasticity maikaʻi loa nā pākeke fiber ceramic a me nā modula, hiki ke wānana ka nui o ka hoʻopiʻi ʻana, a ʻaʻohe pono e haʻalele i nā hono hoʻonui i ka wā o ke kūkulu ʻana. ʻO ka hopena, ua maʻalahi a maʻalahi ke kūkuluʻana, hiki ke hoʻopauʻia e nā limahana akamai maʻamau.
5. Hana me ka umu ʻole
Ma ka hoʻohana ʻana i ka uhi piha-fiber, hiki ke hoʻomaʻamaʻa koke ʻia nā kapuahi i ke kaʻina hana inā ʻaʻole i kaupalena ʻia e nā mea metala ʻē aʻe, e hoʻomaikaʻi maikaʻi ana i ka hoʻohana pono ʻana o nā kapuahi ʻoihana a hōʻemi i ka hoʻohana ʻana i ka wahie pili ʻole.
6. Haʻahaʻa haʻahaʻa thermal conductivity
ʻO ka fiber Ceramic kahi hui o nā fibers me ke anawaena o 3-5um, no laila he haʻahaʻa haʻahaʻa haʻahaʻa. No ka laʻana, i ka wā e hiki ai i ka 128kg/m3 ke kiʻekiʻe-aluminika fiber blanket a hiki i 1000 ℃ ma ka wela wela, ʻo 0.22 (W/MK) wale nō kāna mea hoʻoili wela.
7. Paʻa kemika maikaʻi a me ke kūʻē ʻana i ka ea ea:
Hiki ke hoʻopau wale ʻia ka fiber ceramic i loko o ka waikawa phosphoric, hydrofluoric acid, a me ka alkali wela, a paʻa ia i nā media corrosive ʻē aʻe. Eia kekahi, hana ʻia nā modula fiber ceramic e ka hoʻomau ʻana i ka hoʻopili ʻana i nā pākeke fiber ceramic i kekahi lākiō kōmi. Ma hope o ka mālama ʻia ʻana o ka ʻili, hiki i ka pale ʻana o ka makani ke hiki i 30m / s.
