Ilahle liyakhupha, i-sedimentary, rock rock, eyakhiwa ngokukodwa ngekhabhoni, i-hydrogen kunye ne-oksijini. Yenziwe ngokusuka kwezityalo, ezidibeneyo phakathi kwezinye i-rock strata kwaye ziguqulwe yimiphumo edibeneyo yoxinzelelo kunye nokufudumala kwezigidi zeminyaka ukuze zenze amalahle omlilo.
Ilahlekile yindawo yamanzi kwaye ikhulu kuneoli okanye igesi, malunga ne-119 leminyaka yamalahle asele emhlabeni jikelele.
"Ilahle liyi- fuel fuels and the remaining remains of vegetation pre -istoric originally accumulated in swamps and peat bogs" (World Coal Association).
"Amandla esiwafumana kumakhaza namhlanje avela kumandla atywalayo ukusuka kwilanga ezigidi zeminyaka edlulileyo. Zonke izilwanyana eziphilayo zigcina amandla elanga ngokusebenzisa inkqubo ebizwa ngokuba yi-photosynthesis. Ngokweemeko ezifanelekileyo ukulungiswa kwamalahle, inkqubo yokubola iphazamisekile, inqanda ukukhululwa kwamandla alanga. "Amandla avaliwe kwilahle." (Umthombo: iwebhusayithi ye-Coal Association Association)
"Kuthatha iimitha ezili-10 ze-peat ukwenza i-1 meter yamalahle, kwaye kungathatha iminyaka engama-7 000 ukuqokelela le peat" , ibika iMusic Museum kwiwebhusayithi yayo.
Ngoko ungathini: uvuselelwe okanye awuvuseleleki?
01 Iinkalo zelahle
Ukusuka eLignite ukuya kwi- Anthracite , kwaye ukusuka kwisizukulwana sokuqalisa amandla ukuya kusetyenzisweni lwasekhaya, iintlobo ezahlukeneyo zamalahle zixhomekeke ekukhuleni komzimba kwezityalo. Oku kukhula ngokusobala kwenzeka ngexesha leminyaka ye-geologic kwaye kwavelisa iintlobo ezahlukeneyo zamalahle anika iimpawu ezahlukeneyo (umbala, ubunzima, i-oksijeni, i-hydrogen ne-sulfur balance). Ezi ntlobo ezahlukeneyo zamalahle zigqitywa ngenxa yeenjongo ezahlukeneyo.
Ukususela kwi-peat, umphumo wokuqala wokuguqulwa kwenkqubo yi-lignite (eyaziwa nangokuthi "amalahle omdaka"). Imiphumo eqhubekayo yokushisa kunye noxinzelelo ingashintsha i-lignite ibe ngamalahle angaphantsi kwe-bituminous. Ilahle-bhitumayo i-bituminous ingaba nzima kwaye ibumnyama, ibe iguqulwa ibe yilahle yecala (eyaziwa nangokuthi "ilahle elibi"); Ilahleko lokulahleka liphela ekupheleni kwenkalo yokuziphendukela kwemvelo, equle izinga eliphantsi kakhulu lokungcola.
02 Uphi ilahle?
"Iindawo zokugcina amalahle ziyafumaneka malunga neli lizwe lonke emhlabeni, kunye neendawo zokugcina ezifumanekayo kumazwe angama-70". (Umthombo: Umbutho wamalahle wamazwe)
- Amalahle aqinisekisiwe emhlabeni wonke: ama-toni angama-847 ezigidi
- Oku kuthetha iminyaka eyi-119, kwiirhafu ezikhoyo zamveliso (i-oil proven and gas reserves ilingana neminyaka engama-46 no-63 kumanqanaba okwenziwa kwamanje)
Iindawo zokugcina amalahle zinganwezelwa njani?
- Ukuphonononga ngeteknoloji kunye nenkqubo
- Ukuxhatshazwa okwangoku kungafinyeleleki (ngezizathu zobugcisa kunye / okanye ukhuseleko) kodwa zichonge izixhobo, ngenxa yenkqubela phambili kwezobuchwepheshe
- Ukulungiswa kokusetyenziswa kwamalahle, ukwandisa umlinganiselo wamandla nganye ngetoni yamalahle
