Koho lako wili lanahu 1: wili lanahu wikiwiki haʻahaʻa
ʻO ka mea maʻamau o ka wili lanahu wikiwiki haʻahaʻa ʻo ia ka wili pōpō. ʻO ke kumu hana: ʻo ka mīkini mana kiʻekiʻe ma o ka pahu pahu e hoʻokele i kēia wili papa poepoe kaumaha, hoʻohuli ʻia ka pōpō kila i kahi kiʻekiʻe a laila hāʻule i lalo, ma o ka hopena o ka pōpō kila ma luna o ka lanahu a ma waena o ka pōpō kila, ma waena o ka pōpō kila a me ka papa kiaʻi, wili ʻia ka lanahu. Hoʻokaʻawale ʻia ka lanahu ʻaʻole i hoʻokō ʻia i ka wā e kahe ana ma o ka mea hoʻokaʻawale pauka coarse ma ke kua o ka wili pōpō, a laila hoʻouna ʻia i ka papa poepoe mai ka paipu pauka hoʻihoʻi no ka wili hou ʻana. Ma waho aʻe o ka lawe ʻana i ka pauka lanahu, pāʻani pū ka ea wela i ke kuleana o ka hoʻomaloʻo ʻana i ka lanahu. No laila, ua kapa ʻia hoʻi ka ea wela he desiccant i loko o ka ʻōnaehana pauka. Loaʻa i ka huahana nā ʻano o ka manawa hana lōʻihi, mālama maʻalahi, hoʻopuka paʻa a me ka maikaʻi, hiki ke mālama nui, pane wikiwiki, maʻalahi hana nui, lakio ea-lanahu haʻahaʻa, mālama i ka mīkini lanahu keu, ākea ka wili lanahu a pēlā aku. Hoʻohana nui ʻia no ka lanahu paʻakikī a me ka paʻakikī waena, ʻoi aku hoʻi no ka lanahu me ka ʻike volatile kiʻekiʻe a me ka waiwai abrasive ikaika. Eia nō naʻe, he nui kēia wili pōpō wikiwiki haʻahaʻa, he nui ka hoʻohana ʻana i ka metala, noho i ka nui o ka ʻāina, a he nui ka hoʻopukapuka mua. No laila, kūpono ka wili pōpō no ka hana piha piha.
ʻAno lako wili lanahu 2:wili lanahu wikiwiki waena
ʻIke ʻia hoʻi ka wili lanahu wikiwiki waena ʻo ia ka wili lanahu kū pololei, kahi i hōʻailona ʻia e nā ʻāpana wili i haku ʻia me ʻelua mau hui o ka neʻe pili o ke kino wili. Hoʻopaʻa ʻia ka lanahu a wili ʻia ma waena o nā ʻili o nā kino wili ʻelua a kuʻi ʻia. I ka manawa like, hoʻomaloʻo ka ea wela ma o ka wili i ka lanahu a hoʻouna i ka lanahu i wili ʻia i ka mea hoʻokaʻawale ma ka ʻaoʻao luna o ka wahi wili. Ma hope o ka hoʻokaʻawale ʻana, lawe ʻia ka lanahu i wili ʻia o kekahi nui o nā ʻāpana mai ka wili me ke kahe ʻana o ka ea, a hoʻihoʻi ʻia ka lanahu i wili ʻia i kahi wili no ka wili hou ʻana. Loaʻa i ka wili lanahu wikiwiki waena nā pono o nā lako liʻiliʻi, ka wāwae liʻiliʻi, ka mālama ʻana i ka hoʻohana ʻana i ka mana (ma kahi o 50% ~ 75% o ka wili pōpō), ka walaʻau haʻahaʻa, ka māmā a me ka kaohi hana koʻikoʻi. Akā, ʻaʻole kūpono ia no ka wili ʻana i ka lanahu paʻakikī.
Koho lako wili lanahu 3: wili lanahu wikiwiki
ʻO ka wikiwiki o ka wili lanahu wikiwiki he 500 ~ 1500 r/min, ʻo ia hoʻi ka rotor wikiwiki a me ka pūpū wili. ʻO ka wili peʻahi maʻamau a me ka wili hāmare a pēlā aku. I loko o ka wili, ua kuʻi ʻia ka lanahu e ka hopena wikiwiki a me ka pūpū wili a me ke kuʻi ʻana ma waena o ka lanahu. ʻO kēia ʻano wili lanahu a me ka mea hoʻokaʻawale lanahu i hoʻohui ʻia, he maʻalahi ke ʻano, he paʻa, he haʻahaʻa ka hoʻopukapuka mua, kūpono loa no ka wili ʻana i ka lignite makū kiʻekiʻe a me ka nui o ka volatile, maʻalahi ke wili i ka lanahu bituminous. Eia naʻe, no ka mea ua ʻānai pololei ʻia ka papa hopena a ua ʻaʻahu ʻia e ke kahe o ka ea, ʻo kona ola lawelawe ma kahi o 1000h wale nō i ka wā e wili ai i ka lignite, hoʻololi pinepine ʻia, a ʻaʻole pono e kiʻekiʻe loa ka nui o ka wai o ka lanahu lepo, kahi i hoʻohana pinepine ʻia no nā paila puhi pololei i nā mea kanu mana, a ʻaʻole pono e hoʻohana ʻia no nā hale hana injection umu pahū.
ʻO nā ʻano ʻekolu o ke koho ʻana i nā lako wili lanahu i luna aʻe he mau pono a me nā hemahema, i ke koho ʻana i nā lako wili lanahu, pono e noʻonoʻo i ke koho holoʻokoʻa o ka ʻōnaehana pulverizing. Hiki ke hoʻokaʻawale ʻia ka ʻōnaehana pauka i ʻelua mau māhele: ke ʻano puhi pololei a me ke ʻano mālama waena (i kapa ʻia ʻo ke ʻano mālama). I loko o ka ʻōnaehana pulverization puhi pololei, wili ʻia ka lanahu i loko o ka lanahu pulverized e kahi wili lanahu a laila puhi pololei i loko o ka umu no ke kuni ʻana. I loko o ka ʻōnaehana pulverization mālama, mālama mua ʻia ka lanahu pulverized i loko o ka pahu lanahu pulverized, a laila e like me nā pono o ka ukana paila, hoʻouna ʻia ka lanahu pulverized mai ka pahu lanahu pulverized i ka umu no ke kuni ʻana e ka pulverizer. He kūpono hoʻi nā ʻōnaehana pulverizing like ʻole no nā ʻano like ʻole o ke koho ʻana i nā lako wili lanahu a me nā lako wili lanahu. Wahi a ka ʻōnaehana pulverization, ua hōʻuluʻulu mākou i ke kumu no ke koho ʻana i ka wili lanahu:
(1) ʻO ka wili pōpō kila ma ka ʻōnaehana pauka ea wela waena: hiki ke hoʻohana ʻia no ka anthracite (Vsr<9%) a me ke komo ʻana i ka ikaika ma luna o ka lanahu.
(2) ʻŌnaehana hoʻouna pauka kinoea hoʻopau kikowaena o ka wili pōpō: hoʻohana nui ʻia no ka lanahu me ka lole ikaika a me ka lanahu bituminous waena (Var-19% ~ 27%).
