ʻO ka umu wela wela ka umu hoʻoheheʻe ʻana i ka mea hao nui i ka hana hao.ʻO nā pōhaku lepo alumina kiʻekiʻe, ʻo ia ka huahana kumu o nā mea refractory, hoʻohana nui ʻia i nā umu wela wela.Ma muli o ka nui o ka ʻokoʻa wela ma waena o nā ʻāpana o luna a me lalo o ka umu wela wela, ʻokoʻa loa nā mea refractory i hoʻohana ʻia i kēlā me kēia ʻāpana.ʻO nā wahi nui kahi e hoʻohana ʻia ai nā pōhaku alumina kiʻekiʻe, ʻo ia nā wahi o ka umu ahi wela, nā pā nui, nā regenerators, nā keʻena puhi ahi, a me nā kikoʻī penei:
1. Dome
ʻO ka vault ka wahi e hoʻopili ai i ke keʻena puhi ahi a me ka regenerator, me ka papa hana o nā pōhaku lepo, ka papa hoʻopiha a me ka papa insulation.No ka mea, ʻoi aku ka kiʻekiʻe o ka mahana o ka lua ahi wela, ʻoi aku ma mua o 1400, ʻo nā pōhaku alumina kiʻekiʻe i hoʻohana ʻia i ka papa hana he mau pōhaku alumina kiʻekiʻe.Hiki ke hoʻohana ʻia nā pōhaku silica, nā mullite brick, sillimanite, alusite ma kēia wahi.;
2. Pa nui
ʻO ka pā nui o ka umu wela wela e pili ana i ka ʻāpana pā a puni o ke kino wela wela, me ka papa hana o nā pōhaku lepo, ka papa hoʻopiha a me ka papa insulation.Hoʻohana nā pōhaku lepo hana i nā brick refractory like ʻole e like me nā mahana like ʻole ma luna a ma lalo.Hoʻohana nui ʻia nā pōhaku alumina kiʻekiʻe ma waena a me lalo.
3. Mea hana hou
ʻO ka regenerator kahi wahi i hoʻopiha ʻia me nā pōhaku lepo.ʻO kāna hana nui, ʻo ia ka hoʻohana ʻana i nā brick checker kūloko e hoʻololi i ka wela me ke kinoea flue wela kiʻekiʻe a me ka ea puhi.Ma kēia ʻāpana, hoʻohana ʻia nā pōhaku lepo alumina kiʻekiʻe haʻahaʻa, ma ke kūlana waena.
4. Keena kuni
ʻO ke keʻena kuni ka wahi e puhi ʻia ai ke kinoea.ʻO ka hoʻonohonoho ʻana o ke keʻena ahi he pilina nui me ke ʻano o ka umu ahi a me ke ʻano o ka umu wela wela.Hoʻohana nui ʻia nā pōhaku alumina kiʻekiʻe ma kēia wahi.Hoʻohana ʻia nā pōhaku lepo alumina kiʻekiʻe kiʻekiʻe ma nā wahi wela, a hiki ke hoʻohana ʻia nā pōhaku alumina kiʻekiʻe maʻamau i nā wahi wela a me nā wahi haʻahaʻa.
