Hoʻolauna i ka Lanahu
ʻO ka lanahu kekahi ʻano mineral fossil carbonized.Hoʻonohonoho ʻia e ke kalapona, hydrogen, oxygen, nitrogen a me nā mea ʻē aʻe, ka hapa nui i hoʻohana ʻia e ke kanaka.I kēia manawa, he 63 mau manawa o ka nui o ka lanahu i ʻimi ʻia ma mua o ka ʻaila.Ua kapa ʻia ka lanahu i ke gula ʻeleʻele a me ka meaʻai o ka ʻoihana, ʻo ia ka ikaika nui mai ka kenekulia 18.I ka wā o ka Industrial Revolution, me ka hana ʻana a me ka hoʻohana ʻana i ka ʻenekini mahu, ua hoʻohana nui ʻia ka lanahu e like me ka wahie ʻenehana a lawe mai i nā pūʻali huahana nui ʻole no ka hui.
Hoohana Laahu
Ua māhele ʻia ka lanahu o Kina i ʻumi mau ʻāpana.ʻO ka maʻamau, ʻo ka lanahu wiwi, ka lanahu coking, ka lanahu momona, ka lanahu kinoea, ka hui puʻupuʻu palupalu, ka lanahu ahi lōʻihi i kapa ʻia he lanahu bituminous;Kapa ʻia ka lanahu lean semi Anthracite;Inā ʻoi aku ka nui o ka ʻike ma mua o 40%, ua kapa ʻia ʻo ia he lignite.

Lignite:
ʻO ka hapa nui, ʻeleʻele ʻeleʻele, ʻeleʻele ʻeleʻele, ʻeleʻele kino;Loaʻa iā ia ma kahi o 40% mea volatile, wahi haʻahaʻa haʻahaʻa a maʻalahi ke hopu i ke ahi.Hoʻohana maʻamau ia i ka gasification, liquefaction industry, power boiler, etc.
lanahu bituminous:
ʻO ka mea maʻamau, liʻiliʻi a me ka pauka, ʻeleʻele a ʻālohilohi ka nui, me ke ʻano maikaʻi, ʻoi aku ka nui o ka 30% mea volatile, wahi haʻahaʻa haʻahaʻa a maʻalahi hoʻi e puhi;ʻO ka hapa nui o nā lānahu bituminous he lāʻau paʻa a maʻalahi hoʻi e paʻa i ka wā e puhi ai.Hoʻohana ʻia ia i ka coking, ka hui ʻana o ka lanahu, ka paila mana a me ka ʻoihana gasification.
Anthracite:
ʻElua ʻano o ka pauda a me nā ʻāpana liʻiliʻi, ʻo ia ka ʻeleʻele, metala a me ka ʻālohilohi.ʻO nā mea haumia liʻiliʻi, ke ʻano paʻa, ka ʻike kalapona paʻa kiʻekiʻe, a hiki i ka 80%;ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa, ma lalo o 10%, ʻoi aku ka kiʻekiʻe o ke ahi, a ʻaʻole maʻalahi ke hopu i ke ahi.E hoʻohui ʻia ka nui o ka lanahu a me ka lepo no ka puhi ʻana i mea e hoʻemi ai i ka ikaika o ke ahi.Hiki ke hoʻohana ʻia e hana i ke kinoea a i ʻole e like me ka wahie.
Kaʻina hana o ka pulverization lanahu
No ka wili lanahu, ua hoʻokumu ʻia ma luna o kāna helu hiki ke hoʻololi ʻia ʻo Harzburg.ʻOi aku 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 (55-60).
ʻŌlelo:
① koho i ka mīkini nui e like me ka hoʻopuka a me nā koi maikaʻi;
② Ke noi nui: ka lanahu pulverized thermal
Ka nānā 'ana i nā mea wili wili
1. Ka hale wili pendulum (HC, HCQ series pulverized coal mill):
ʻO ke kumu kūʻai haʻahaʻa haʻahaʻa, hoʻopuka kiʻekiʻe, hoʻohana haʻahaʻa haʻahaʻa, nā lako paʻa a me ka leo haʻahaʻa;ʻO ka drawback, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka hana a me ka mālama ʻana ma mua o ka wili paʻa.
