Nhasi tichataura nezverudzi rwemagetsi rwunogadzirwa nekupisa kwemafuta uye kuti magetsi anogadzirwa. Ndezve iyo simba remagetsi. Pakati pemafuta epamusoro anoshandiswa ese emvura uye ane gasi tine marasha, oiri, gasi rechisikigo, naphtha uye biomass. Iyo mhando yesimba inomiririra 80% yemagetsi anoshandiswa pasirese.
Muchikamu chino tiri kukuudza zvese zvaunoda kuti uzive nezvesimba remagetsi, zvakanakira nekuipira.
Mhando huru
Imhando yesimba rinoshandisa kupisa kugadzira magetsi. Iyo michina yeiyi yakafanana chaizvo neiyo yeimwe thermoelectric kuiswa. Nekudaro, iyo nzira yekutanga mashini yakasiyana. Iyo huru mashini ye thermoelectric simba Izvo zvinoenderana nekushandisa kupisa kuti ugone kuwedzera tembiricha yemvura. Imwe mune dzakawanda kesi mvura inoshandiswa mvura. Kana mvura yapera kubuda, chiutsi chakashandiswa kufambisa turbine iyo yakatanga kutenderera. Nenzira iyi, simba remafuta rinoshandurwa kuita kinetic simba.
Iyo turbine iyo inotanga kufamba yakabatana kune jenareta iyo inogona kuburitsa magetsi nekuda kwekufamba. Simba remhepo rave richishandiswa munhoroondo yese uye nekuda kwechikonzero ichi simba remagetsi rinopararira kwazvo pasirese.
Mhando dzesermoelectric simba
Rudzi urwu rwesimba runogona kuiswa muzvikamu nenzira dzakasiyana zvichienderana nenzira yaunogadzirwa. Chekutanga pane zvese, funga nezve mafuta anoshandiswa kugadzira kupisa uko kunopa magetsi. Tichaona kuti ndedzipi dzakasiyana mhando dzesimba remagetsi erudzi ruripo.
Thermoelectric simba kubva kune fossil fuels
Iyi ndiyo yakanyanya kushandiswa munhoroondo yese uye inoenderana zvakanyanya nekupisa mafosili ekugadzira kupisa uye gare gare simba rekineti. Mafuta emafuta haakwidziridzike uye igasi rechisikigo, marasha uye, kusvika padiki padiki, mafuta. Kupisa zvisaririra zvinogadzira kupisa uko kunoshandiswa kugadzira chinoyerera uye kutyaira turbine. Kana turbine yatanga kufamba, jenareta ndiye anotarisira kugadzira magetsi.
Dambudziko nefossil mafuta thermoelectric simba ndiko kusvibiswa kwaunogadzira uye kupera kwemafuta. Nhasi fossil fuel thermoelectric simba ndiyo sosi hombe yemagetsi pasirese. Anenge mamirioni gumi GWh emagetsi akagadzirwa nemarasha uye angangoita mamirioni matanhatu ekuwedzera GWh akagadzirwa negasi rechisikigo. Izvi zvinoreva zvinopfuura 6% yesimba rakagadzirwa muna 60.
Kunyangwe hazvo marasha ari kuburitsa kudzikira kwepasirese kuri kudhura kupfuura kumutsidzirwa, fossil-based thermoelectric energy ndiyo yakanyanya kukosha pasirese.
Thermoelectric simba renyukireya rakatangira
Tichaona kuti rudzii rwesimba renyukireya thermoelectric simba uye kuti rinoitwa sei. Mune ino kesi, kugadzira simba kubva kumafuta anoshandiswa iuranium. Plutonium inoshandiswa zvishoma. Kuwedzera tembiricha yemvura uye kugadzira mweya, uranium inoshandiswa kuburikidza neiyo nyukireya fission maitiro mukati meiyo reactor mune nyukireya magetsi chirimwa. Utsi hunowanikwa muzvirimwa zvine simba renyukireya hunobuda muzvimney mhute yemvura uye kwete carbon dioxide sekufunga kwevanhu vazhinji.
Thermoelectric simba rekudzoreredza mavambo
Seizvo izwi rayo pacharo rinoratidza iri mhando yesimba rinoshandisa zviwanikwa zvinowedzerwazve kuwedzera kudziya kwemvura uye kugadzira mweya Ngatione kuti ndeapi maviri akakosha madiki esimba:
- Geothermal: Ndiyo imwe inotora mukana wekupisa kwechisikigo kubva mukati mevhu kuburitsa mvura uye kugadzira magetsi.
- Solar kupisa simba: Ndiro rinoita basa rekutora kupisa kubva kuzuva kuitira kuti riite semhepo. Kubva ipapo unowana magetsi anodiwa.
Thermoelectric simba kubva kumagetsi anovandudzwa rine chikamu chidiki chemagetsi ekugadzira pasirese.
Kubatsirwa
Ngatione kuti ndezvipi zvakanakira simba remagetsi:
- Kana tikazvienzanisa neiyo Magetsi emagetsi emagetsi anokurumidza kuvaka. Nenzira iyi, unogona kuvhara kushomeka kwesimba nekukurumidza uye nemitengo yakaderera yekugadzira.
- Iwe unogona kuisa munzvimbo dziri padyo nevatengi matunhu. Nekuda kweizvi, mutengo weshongwe uye nzira dzekufambisa dzinogona kudzikiswa. Imwe yemitengo yepamusoro yesimba remagetsi kuchengetedza kwayo uye kutakura. Kana ichigona kuvakwa munzvimbo dziri padyo nenzvimbo dzinoshandiswa, isu tinochengetedza izvi mutengo.
- Iyo imwe nzira kune nyika dzisina imwe mhando yesimba sosi.
payakaipira
Kufanana chero chero mhando yesimba sosi, iyo thermoelectric inewo zvimwe zvinetswa. Sezvo mafuta emafuta achishandiswa kupisa uye kugadzira simba, pane huwandu hwakawanda hwezvinhu zvinosvibisa zvinoburitsirwa mudenga. Zvinosvibisa zviri kukonzera kudziya kwepasi uye shanduko yemamiriro ekunze. Iyo haingogadzi chete kuwedzera kwepasirese tembiricha, asi zvakare inokonzeresa huwandu hukuru hwezvirwere zvemoyo uye zvekufema. Maguta makuru akazara magasi anokuvadza ari kukonzera kuwanda kwezvirwere muhuwandu hwevanhu. Kusvibiswa kwemweya ndechimwe chezvinetso zvakakomba zvakatarisana nevanhu muzana rino ramakore.
Chimwe chakakanganisika ndechekuti mutengo wekupedzisira werudzi urwu rwesimba wakakwira kupfuura uya unogadzirwa mumagetsi emagetsi. Izvo zvinofanirwawo kutarisirwa kuti mutengo unosiyana kubva nguva kusvika pane zvinoenderana nemafuta. Uye ndezvekuti mitengo iyi inoshanduka zuva nezuva uye pane kuchinja kunochinja zvakanyanya simba remagetsi.
Sezvauri kuona, iri rakakosha mhando yesimba asi rinofanira kuenda pasi munhoroondo. Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezvazvo.
