Ukuqonda amalahle oMphunga angaphekiyo: Isikhokelo esiBanzi

Esi sikhokelo sinika amagqabantshintshi abanzi umphunga wamalahle angaphekiyo, iphonononga iipropati zayo, usetyenziso, kunye namandla emarike. Siza kugocagoca kwiimpawu zayo ezahlukileyo xa kuthelekiswa namalahle okuphekela, sivavanye iindlela asetyenziswa ngazo kumashishini ahlukeneyo, kwaye sixoxe ngentsingiselo yangoku yemarike enefuthe kubonelelo kunye nemfuno yayo. Funda malunga nezinto eziphambili eziphembelela ixabiso layo kunye nenkangeleko yexesha elizayo yesi sixhobo samandla esibalulekileyo.

Yintoni amalahle angapheki ngomphunga?

Umphunga wamalahle angaphekiyo, ngokungafaniyo namalahle okuphekela asetyenziswa kwi-steelmaking, luhlobo lwamalahle olusetyenziselwa ukuveliswa komphunga kwizityalo zamandla. Ibonakala ngomxholo wayo osezantsi oguquguqukayo kunye nexabiso elisezantsi le calorific xa kuthelekiswa namalahle okucokisa. Olu hlobo lwamalahle luhamba kwinkqubo apho lutshiswe khona ukuze luvelise ubushushu, obuguqula amanzi abe ngumphunga, emva koko aqhube iiinjini zomoya ukuvelisa umbane. Umgangatho kunye neempawu ze umphunga wamalahle angaphekiyo ziyahluka ngokuxhomekeke kwimvelaphi yayo yokwakheka komhlaba kunye nokwakheka. Iimpawu eziphambili zibandakanya umxholo walo womlotha, umxholo wesulfure, kunye nexabiso lokufudumala. Ezi mpawu zinempembelelo kakhulu ekulungelweni kwayo kwizicelo ezahlukeneyo.

IiPropathi eziPhambili zoMphunga ongaPhekiyo wamalahle

Umgangatho we umphunga wamalahle angaphekiyo imiselwa yimiba emininzi ebalulekileyo echaphazela ukusebenza kwayo kokutsha kunye nefuthe lokusingqongileyo. Ukuqonda ezi propati kubalulekile ekukhetheni uhlobo olufanelekileyo lwamalahle kwiimfuno ezithile zokuvelisa amandla.

Isiqulatho sothuthu

Isiqulatho sothuthu oluphezulu sinciphisa ixabiso lokufudumeza amalahle kwaye kunokukhokelela ekunyuseni kweemfuno zokulondolozwa kwizityalo zamandla ngenxa yokwakhiwa kothuthu. Isiqulatho sothuthu esisezantsi sikhethwa ngokubanzi.

Umxholo wesulfure

Isiqulatho sesulfure esiphezulu sinegalelo kungcoliseko lomoya, okukhokelela kwimvula eneasidi kunye neminye imiba yokusingqongileyo. Imimiselo ihlala ibeka imida kwisiqulatho sesulfure kumalahle asetyenziselwa ukuvelisa amandla.

Ixabiso lokufudumeza

Ixabiso lokufudumeza (elidla ngokuchazwa kwi-BTU/lb okanye i-MJ/kg) limele ubungakanani bobushushu obukhutshwayo xa iyunithi yobunzima bamalahle itshiswa ngokupheleleyo. Amaxabiso aphezulu okufudumeza anqweneleka ngakumbi ekwenzeni umbane osebenzayo.

Umba oguquguqukayo

Umxholo wezinto eziguquguqukayo uphembelela iimpawu zokutsha zamalahle. Ngelixa ukupheka amalahle kunento eninzi eguquguqukayo, umphunga wamalahle angaphekiyo ngokuqhelekileyo inomxholo ophantsi, ochaphazela iimpawu zayo ezivuthayo kunye nokusebenza kakuhle.

Usetyenziso lwe-Steam Non-Coal Coal

Usetyenziso oluphambili lwe umphunga wamalahle angaphekiyo ikwimveliso yamandla. Nangona kunjalo, iphinda ifumane ukusetyenziswa kwezinye iinkqubo zoshishino.

IsiZukulwana saMandla

Olu lolona setyenziso lubalaseleyo, kunye nezixhobo zombane ezibaswa ngamalahle ezininzi ezixhomekeke kuyo umphunga wamalahle angaphekiyo njengomthombo wabo wokuqala wamafutha okuvelisa umbane. Ukutsha kwamalahle kuvelisa ubushushu obubilise amanzi ukwenza umphunga woxinzelelo oluphezulu. Lo mphunga ke uqhuba iiinjini zomoya, ezivelisa umbane.

Ukufudumeza kwamashishini

Kwiinkqubo ezithile zoshishino, umphunga wamalahle angaphekiyo ingasetyenziswa njengomthombo wobushushu kwizicelo ezahlukeneyo ezifana nemveliso yesamente okanye ezinye iinkqubo zoshishino lobushushu obuphezulu.

IiNdlela zeMarike kunye neNgcaciso yoMphunga ongaPhekiyo wamalahle

Imarike yehlabathi ye umphunga wamalahle angaphekiyo iyatshintsha kwaye iphenjelelwa zizinto ezininzi, ezibandakanya imimiselo yokusingqongileyo, imfuno yamandla, kunye nenkqubela phambili yobuchwepheshe. Ukwanda kolwazi lokukhutshwa kwerhasi yegreenhouse kukhokelela ekutshintsheni kwimithombo yamandla acocekileyo, okunokuba nefuthe kwimfuno yexesha elide yamalahle. Nangona kunjalo, kwimimandla emininzi, amalahle ayaqhubeka ukudlala indima ebalulekileyo ekuveliseni umbane, ukugcina imfuno enkulu yombane. umphunga wamalahle angaphekiyo.

Ukuqukumbela

Ukuqonda iipropathi, usetyenziso, kunye neentshukumo zentengiso ze umphunga wamalahle angaphekiyo ibalulekile kubachaphazeli abohlukeneyo, ukusuka kubasebenzisi bemizi-mveliso yamandla ukuya kubaqulunqi bomgaqo-nkqubo. Ngelixa imbonakalo yamandla iguquka, umphunga wamalahle angaphekiyo kulindeleke ukuba ihlale ingumthombo wamandla obalulekileyo kwixesha elizayo, ngakumbi kwimimandla enoovimba abaninzi kunye neziseko ezingundoqo ezimiselweyo. Uphando olongezelelweyo kunye nokuqaliswa kwezinto ezintsha kubuchwephesha bamalahle acocekileyo kunokunceda ukunciphisa iimpembelelo zokusingqongileyo ezinxulumene nokusetyenziswa kwawo.

Ngolwazi oluthe kratya malunga nemithombo yamalahle ekumgangatho ophezulu, qwalasela ukuhlola I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd.
