Hoʻolauna i ka Lanahu
He ʻano mineral fossil kalapona ka lanahu. Hoʻonohonoho ʻia e ke kalapona, hydrogen, oxygen, nitrogen a me nā mea ʻē aʻe, ʻo ka hapa nui i hoʻohana ʻia e ke kanaka ma ke ʻano he wahie. I kēia manawa, ʻo ka lanahu he 63 mau manawa o ka nui o ka waihona i ʻimi ʻia ma mua o ka petroleum. Ua kapa ʻia ka lanahu ʻo ke gula ʻeleʻele a ʻo ka meaʻai o ka ʻoihana, ʻo ia ka ikehu nui mai ke kenekulia 18. I ka wā o ka Industrial Revolution, me ka hana ʻana a me ka hoʻohana ʻana i ka mīkini mahu, ua hoʻohana nui ʻia ka lanahu ma ke ʻano he wahie ʻoihana a ua lawe mai i nā mana hana nui i ʻike ʻole ʻia no ke kaiāulu.
Hoʻohana ʻana i ka lanahu
Ua māhele ʻia ka lanahu Kina i ʻumi mau ʻano. Ma ke ʻano laulā, ʻo ka lanahu wīwī, ka lanahu coking, ka lanahu momona, ka lanahu kinoea, ka lanahu palupalu, ka lanahu unbonded a me ka lanahu lapalapa lōʻihi e kapa ʻia he lanahu bituminous; Ua kapa ʻia ka lanahu wīwī he semi Anthracite; Inā ʻoi aku ka nui o ka volatile ma mua o 40%, ua kapa ʻia ʻo ia he lignite.

Lignite:
ʻO ka hapa nui, ʻeleʻele ʻeleʻele, ʻōlinolino ʻeleʻele, ʻano palupalu; Loaʻa iā ia ma kahi o 40% o nā mea lele, haʻahaʻa ke kiko hoʻā a maʻalahi ke puhi ʻia. Hoʻohana nui ʻia ia i ka gasification, ka ʻoihana liquefaction, ka paila mana, a pēlā aku.
Lanahu bituminous:
He ʻano granular ia, liʻiliʻi a pauka, ʻeleʻele a ʻālohilohi ka hapa nui, me ke ʻano maikaʻi, aia ma mua o 30% o nā mea lele, haʻahaʻa ke kiko hoʻā a maʻalahi ke hoʻā; ʻO ka hapa nui o nā lanahu bituminous he pipili a maʻalahi ke slag i ka wā e puhi ai. Hoʻohana ʻia ia i ka coking, ka hoʻohuihui lanahu, ka paila mana a me ka ʻoihana gasification.
ʻAnetaketa:
ʻElua ʻano pauka a me nā ʻāpana liʻiliʻi, he ʻeleʻele, he metala a he ʻālohilohi. ʻOi aku ka liʻiliʻi o nā haumia, ʻano paʻa, kiʻekiʻe ka nui o ke kalapona paʻa, a hiki i ka 80%; Haʻahaʻa ka nui o ka volatile, ma lalo o 10%, kiʻekiʻe ke kiko hoʻā, a ʻaʻole maʻalahi ke puhi ʻia. Pono e hoʻohui ʻia ka nui kūpono o ka lanahu a me ka lepo no ke kuni ʻana e hōʻemi i ka ikaika o ke ahi. Hiki ke hoʻohana ʻia e hana i ke kinoea a i ʻole pololei ma ke ʻano he wahie.
Kaʻina hana o ka pulverization lanahu
No ka wili ʻana i ka lanahu, ua hoʻokumu nui ʻia ia ma luna o kona coefficient grindability Harzburg. ʻO ka nui o ka coefficient grindability Harzburg, ʻoi aku ka maikaʻi o ka wili ʻana (≥ 65), a ʻo ka liʻiliʻi o ka coefficient grindability Harzburg, ʻoi aku ka paʻakikī o ka wili ʻana (55-60).
Nā Manaʻo:
① koho i ka mīkini nui e like me nā koi hoʻopuka a me ka fineness;
② Ka hoʻohana nui: lanahu i hoʻoheheʻe ʻia i ka wela
