Ho Utloisisa le ho Laola Likotsi Tsa ho Chesa Leshala

Sengoliloeng sena se fana ka kakaretso e felletseng ea leshala le chesang, ho hlahloba thepa ea eona, lits'ebetso, le likotsi tse amanang le tikoloho le polokeho. Re hlahlobisisa lits'ebetso tse amehang ts'ebelisong ea eona, ho hlahloba mekhoa e metle bakeng sa ho fokotsa litlamorao tse mpe le ho netefatsa ts'ebetso e nang le boikarabelo. Ithute ka mefuta e fapaneng ea leshala le chesang, litšobotsi tsa bona, le mokhoa oa ho khetha mofuta o nepahetseng bakeng sa lisebelisoa tse khethehileng. Re boetse re buisana ka boikamahanyo ba taolo le likhatelopele tsa morao-rao tsa ho fokotsa sekhahla sa tikoloho ea leshala le chesang tshebediso.

Ho chesa Mashala ke Eng?

Leshala le chesang, eo hape e tsejoang e le mashala a futhumatsang, ke mofuta oa mashala ao haholo-holo a sebelisetsoang ho fehla motlakase litsing tsa motlakase tse futhumatsang mocheso. E tsebahala ka matla a eona a mangata le sebabole se batlang se le tlase, e leng se etsang hore e loketse ho chesoa ka har'a liboiler. Mokhoa ona o kenyelletsa ho chesa mashala ho hlahisa mocheso, oo joale o hlahisang mouoane ho khanna li-turbine le ho hlahisa motlakase. Khetho e nepahetseng leshala le chesang e bohlokoa bakeng sa ts'ebetso e nepahetseng ea polante ea motlakase le ho fokotsa mesi.

Mefuta ea Mashala a Mouoane

Mefuta e mengata ea mashala e khetholloa e le leshala le chesang, se seng le se seng se na le litšobotsi tse fapaneng. Liphapang tsena li susumetsa ho tšoaneleha ha tsona bakeng sa limela tse fapaneng tsa matla le lits'ebetso. Litšobotsi tsa bohlokoa li kenyelletsa boemo (mohlala, bituminous, sub-bituminous, lignite), litaba tse sa tsitsang, molora le sebabole.

Leshala la Bituminous

Mashala a bituminous ke mofuta o tloaelehileng oa leshala le chesang, e khetholloang ka matla a eona a matla a matla le mongobo o batlang o le tlaase. E chesa habonolo le ka mokhoa o nepahetseng, e leng se etsang hore e be khetho e tsebahalang bakeng sa tlhahiso ea matla a maholo. Leha ho le joalo, e ka boela ea e-ba le sebabole se phahameng ha se bapisoa le mefuta e meng, e hlokang mehato e eketsehileng bakeng sa taolo ea mocheso.

Sub-bituminous Mashala

Mashala a sub-bituminous a na le matla a tlase ho feta mashala a bituminous empa hangata a na le sebabole se tlase. Sena se e etsa sebaka se seng se loketseng libakeng tse nang le melaoana e thata ea tlhahiso. Boleng ba eona bo tlase ba khalori bo ka hloka hore ho lokisoe meralo ea boiler le liparamente tsa ts'ebetso.

Leshala la Lignite

Mashala a Lignite, a tsejoang hape e le mashala a sootho, a na le matla a tlase ka ho fetisisa har'a leshala le chesang mefuta. Mongobo oa eona o phahameng o hloka hore ho be le liphetoho tse mabapi le ho tšoara le ho chesa. Le hoja hangata e le theko e tlaase, ts'ebetso ea eona e tlaase le likhase tse phahameng li kenya letsoho ho ba le tšusumetso e kholo ea tikoloho.

Liphello tsa Tikoloho le Litlhokomelo tsa Polokeho

Ho tuka ha leshala le chesang e ntša likhase tse futhumatsang lefatše, ho akarelletsa le carbon dioxide (CO2), tse tlatsetsang phetohong ea boemo ba leholimo. Lintho tse ling tse silafatsang tse lokollotsoeng li kenyelletsa sulfur oxides (SOx), nitrogen oxides (NOx), particulate matter (PM), le mercury. Mesi ena e ka ba le litlamorao tse kholo ho boleng ba moea le bophelo bo botle ba batho. Tšoaro e nepahetseng le polokelo ea leshala le chesang li bohlokoa hape ho thibela likotsi tse kang ho phatloha ha lerōle le mollo.

Ho Fokotsa Liphello Tsa Tikoloho

Ho sebelisoa theknoloji le mekhoa e fapaneng ho fokotsa tšusumetso ea tikoloho ea leshala le chesang tshebediso. Tsena li kenyelletsa:

• Flue gas desulfurization (FGD) ho tlosa SOx
• Selection catalytic reduction (SCR) ho fokotsa NOx
• Lisebelisoa tsa ho laola lintho tse itseng (mohlala, li-precipitator tsa electrostatic, filters tsa masela)
• Theknoloji ea ho hapa le ho boloka carbon (CCS).
• Mekhoa e ntlafetseng ea ho chesa mollo bakeng sa ts'ebetso e ntlafetseng

Tumellano ea Taolo le Mekhoa e Molemohali

Melao e thata e laola tšebeliso le ts'ebetso ea leshala le chesang ho sireletsa tikoloho le bophelo bo botle ba sechaba. Basebelisi ba lifeme tsa motlakase ba tlameha ho ikamahanya le melaoana ena, hangata e kenyelletsang tlhahlobo ea mosi, ho tlaleha, le litlhoko tsa tumello. Ho latela melaoana ea polokeho ho bohlokoa ho thibela likotsi le ho netefatsa boiketlo ba basebetsi le sechaba se haufi.

Ho Khetha Leshala le Nepahetseng la Mouoane

Khetho e nepahetseng leshala le chesang bakeng sa setsi sa motlakase se kenyelletsa tlhahlobo e hlokolosi ea lintlha tse 'maloa, ho kenyelletsa:

Ho shebisisa lintlha tsena ka hloko ho netefatsa tlhahiso e nepahetseng ea matla le ho fokotsa tšusumetso ea tikoloho. Ikopanye le litsebi tsa indasteri le mekhatlo ea taolo ho netefatsa hore ho latela melao le mekhoa e metle.

Bakeng sa tlhaiso-leseling e batsi ka litharollo tsa motlakase tse tšoarellang, nahana ka ho hlahloba mehloli e meng ea matla. Inner Mongolia Xinxin Silicon Industry Co.,Ltd e ikemiselitse ho fana ka litharollo tse ncha bakeng sa bokamoso bo hloekileng ba eneji.

¹ Lintlha tse mabapi le thepa ea mashala li ka fumanoa liphuputsong tse fapaneng tsa jeoloji le likhatisong tsa indasteri. Ka kopo sheba mehloli e amehang bakeng sa litlhoko tse khethehileng tsa data.
