Kumvetsetsa ndi Kuwongolera Kuopsa kwa Kuwotcha Malasha

Nkhaniyi ikupereka chithunzithunzi chokwanira cha malasha oyaka, kuyang'ana katundu wake, ntchito, ndi zoopsa zokhudzana ndi chilengedwe ndi chitetezo. Timafufuza njira zomwe zimagwiritsidwira ntchito, ndikuwunika njira zabwino zochepetsera zoyipa ndikuwonetsetsa kuti zikuyenda bwino. Phunzirani za mitundu yosiyanasiyana ya malasha oyaka, mawonekedwe awo, ndi momwe mungasankhire mtundu woyenera wa ntchito zinazake. Timakambirananso za kutsata malamulo komanso kupita patsogolo kwaposachedwa pakuchepetsa kufalikira kwa chilengedwe malasha oyaka kugwiritsa ntchito.

Kodi Kutentha Malasha ndi Chiyani?

Makala oyaka moto, yomwe imadziwikanso kuti malasha amoto, ndi mtundu wa malasha omwe amagwiritsidwa ntchito makamaka popanga magetsi m'mafakitale opangira magetsi. Imadziwika ndi mphamvu zake zambiri komanso sulfure yochepa, zomwe zimapangitsa kuti zikhale zoyenera kuyaka m'ma boilers. Njirayi imaphatikizapo kuwotcha malasha kuti apange kutentha, komwe kumatulutsa nthunzi kuti iyendetse ma turbines ndi kupanga magetsi. Kusankhidwa koyenera malasha oyaka ndizofunikira kuti magetsi azigwira bwino ntchito komanso kuchepetsa kutulutsa mpweya.

Mitundu Ya Makala Otentha

Mitundu ingapo ya malasha imagawidwa ngati malasha oyaka, chilichonse chimakhala ndi zinthu zosiyanasiyana. Kusiyanaku kumakhudza kuyenerera kwawo kwamagetsi osiyanasiyana ndi ntchito. Makhalidwe ofunika kwambiri amaphatikizapo udindo (mwachitsanzo, bituminous, sub-bituminous, lignite), zinthu zowonongeka, phulusa, ndi sulfure.

Malasha a Bituminous

Malasha a bituminous ndi mtundu wamba wa malasha oyaka, yodziwika ndi kachulukidwe kake kamphamvu komanso chinyezi chochepa. Imayaka mosavuta komanso moyenera, ndikupangitsa kukhala chisankho chodziwika bwino pakupanga mphamvu zazikulu. Komabe, imathanso kukhala ndi sulfure yambiri poyerekeza ndi mitundu ina, zomwe zimafuna njira zowonjezera zowongolera umuna.

Malasha a Sub-bituminous

Malasha apansi pa bituminous ali ndi mphamvu zochepa kuposa malasha a bituminous koma nthawi zambiri amakhala ndi sulfure yochepa. Izi zimapangitsa kukhala njira yabwino m'madera omwe ali ndi malamulo okhwima otulutsa mpweya. Kutsika kwake kwa calorific kungafunike kusintha kwa mapangidwe a boiler ndi magawo ogwiritsira ntchito.

Malasha a Lignite

Malasha a Lignite, omwe amadziwikanso kuti malasha a bulauni, ali ndi mphamvu zochepa kwambiri pakati pawo malasha oyaka mitundu. Kuchuluka kwa chinyezi kumapangitsa kuti pakhale kusintha kwa kayendetsedwe kake ndi kuyaka. Ngakhale kuti nthawi zambiri imakhala yotsika mtengo, kutsika kwake kosagwira ntchito komanso kutulutsa mpweya wambiri kumathandizira kuwononga chilengedwe.

Zokhudza Zachilengedwe ndi Kuganizira Zachitetezo

Kuyaka kwa malasha oyaka amatulutsa mpweya wowonjezera kutentha, kuphatikizapo mpweya woipa (CO2), womwe umathandizira kusintha kwanyengo. Zina zowononga zomwe zimatulutsidwa ndi sulfure oxides (SOx), nitrogen oxides (NOx), particulate matter (PM), ndi mercury. Kutulutsa kumeneku kumatha kukhudza kwambiri mpweya komanso thanzi la anthu. Kusamalira moyenera ndi kusunga malasha oyaka ndizofunikanso kupewa ngozi monga kuphulika kwafumbi ndi moto.

Kuchepetsa Kuwonongeka Kwachilengedwe

Tekinoloje ndi machitidwe osiyanasiyana amagwiritsidwa ntchito kuti achepetse kuwonongeka kwa chilengedwe malasha oyaka kugwiritsa ntchito. Izi zikuphatikizapo:

• Flue gas desulfurization (FGD) kuchotsa SOx
• Selective catalytic reduction (SCR) kuti muchepetse NOx
• Zipangizo zowongolera zinthu (monga ma electrostatic precipitators, zosefera nsalu)
• Tekinoloje ya Carbon Capture and Storage (CCS).
• Kupititsa patsogolo njira zoyatsira kuti ziwonjezeke bwino

Kutsata Malamulo ndi Njira Zabwino Kwambiri

Malamulo okhwima amalamulira kagwiritsidwe ntchito ndi kasamalidwe ka malasha oyaka kuteteza chilengedwe ndi thanzi la anthu. Oyendetsa mafakitale amagetsi amayenera kutsatira malamulowa, omwe nthawi zambiri amakhudza kuyang'anira utsi, kupereka malipoti, ndi zofunikira za chilolezo. Kutsatira ndondomeko zachitetezo ndikofunikira kwambiri kuti tipewe ngozi ndikuwonetsetsa kuti ogwira ntchito ndi anthu ozungulira amakhala ndi moyo wabwino.

Kusankha Malasha Otentha Oyenera

Kusankhidwa koyenera malasha oyaka kwa chopangira magetsi kumaphatikizapo kuwunika mosamala zinthu zingapo, kuphatikiza:

Kuganizira mozama pazifukwa izi kumapangitsa kuti magetsi azikhala oyenera komanso kuchepetsa kuwonongeka kwa chilengedwe. Kambiranani ndi akatswiri amakampani ndi mabungwe owongolera kuti muwonetsetse kuti zikutsatiridwa ndi machitidwe abwino.

Kuti mumve zambiri pazayankho zamphamvu zokhazikika, lingalirani zofufuza njira zina zopangira mphamvu. Malingaliro a kampani Inner Mongolia Xinxin Silicon Industry Co.,Ltd yadzipereka kupereka njira zatsopano zopezera mphamvu zamtsogolo.

¹ Zambiri pazachuma za malasha zitha kupezeka m'mafukufuku osiyanasiyana a geological ndi zolemba zamakampani. Chonde funsani komwe kuli koyenera kuti mupeze zofunikira zenizeni za data.
