I-Lignite, eyaziwa nangokuthi i-semi - coke, uphethiloli oqinile okhishwe kumalahle ngoThempeli ophansi -. Eminyakeni yamuva nje, ngokukhula kwesidingo somhlaba wonke samandla ahlanzekile kanye nezinto zokwakha imvelo, i-lignite idonsele ukunakwa okubanzi emikhakheni yamandla, imboni yamakhemikhali kanye ne-metallurgy ngenxa yezinzuzo zayo ezihlukile.
I-Lignite ikhiqizwa ikakhulukazi yi-lise - yokushisa lokushisa, futhi izinga lokushisa livame ukulawulwa phakathi kwama-500 nama-800 degrees Celsius. Uma kuqhathaniswa nokuhlanganiswa kwamalahle endabuko, le nqubo inganciphisa kakhulu ukuphuma kwezinto eziyingozi ezifana nesibabule kanye ne-nitrogen, ngenkathi igcina okuqukethwe okuphezulu kwekhabhoni nenani lekhalobhoni. Idatha ikhombisa ukuthi inani le-calorific le-lignite lingafinyelela kuma-5500 kuya ku-7000 kcal, okusondelene nezinga lamalahle aphezulu aphezulu, kepha ukukhishwa okungcolisayo kuncishiswa kakhulu, okwenza kube yindlela yokuvikela amandla ngokusebenza kahle kanye nezimpawu zokuvikela ezemvelo.
Ensimini yesicelo, i-liginite ikhombisa amandla ahlukahlukene. Embonini ye-metallurgical, i-lignite ingasetshenziswa njenge-blast lisac full joinect uphethiloli ukuze ungene esikhundleni sengxenye ye-coke, yehlise izindleko zokukhiqiza futhi wehlise ukuphuma kwekhabhoni. Embonini yamakhemikhali, i-lignite ingasetshenziselwa ukukhiqiza imikhiqizo efana ne-calcium carbide kanye nekhabhoni eyenziwe yasebenza. Umlotha waso ophansi kanye nezimpawu eziphansi ze-sulfur zisiza ukuthuthukisa ubumsulwa bemikhiqizo engezansi. Ngaphezu kwalokho, iLignite isetshenziswa kabanzi ekufuneni komphakathi kanye nophethiloli wezimboni, ikakhulukazi ezindaweni ezinezidingo eziphakeme zemvelo. Izici zalo eziphansi eziphansi zenza kube yinto engcono kakhulu yamalahle endabuko.
Ngokombono wemakethe yamazwe omhlaba, isidingo se-Lignite sikhula ngokuqinile. Isidingo samandla ahlanzekile emazweni amaningi siqhubekele ekuthumelweni kwamanye amazwe, ikakhulukazi eSoutheast Asia, eMiddle East naseYurophu. Ngenxa yezinzuzo zayo zemvelo kanye nokusekelwa kwenqubomgomo, i-lignite iqhubeke yandisa isabelo semakethe yayo. Ngasikhathi sinye, ngokuthuthuka kobuchwepheshe bokukhiqiza, izindleko zokukhiqiza ze-Lignite zinciphile kancane kancane, zithuthukisa ezinye ukuncintisana kwawo kwemakethe.
Esikhathini esizayo, njengoba ukwakheka kwamandla emhlabeni jikelele kuguqukela ku-carbonization ephansi -, i-liginite kulindeleke ukuthi idlale indima ebalulekile ebangeni elibanzi lezinkambu. Ukusebenza kwayo okuphezulu kanye nezici ezihlanzekile akuhambelani nokuthambekela kwentuthuko esimeme, kepha futhi zinikeze amaphuzu amasha okukhula amaketanga ahlobene nezimboni.
