Iyini Amandla Okushisa?

Amandla okushisa ugesi okhiqizwa ngokusebenzisa ukushisa. Isikhathi esiningi, lokhu kushisa kusetshenziselwa ukuguqula amanzi abe umusi ocindezelayo, bese ujikeleza i-turbine exhunywe kujeneretha, ikhiqize ugesi.

Into ebalulekile okufanele uyikhumbule ukuthi amandla okushisa aguqula amandla okushisa (ukushisa) abe amandla kagesi.

Isebenza Kanjani Isitshalo Sikagesi Esishisayo? (Inqubo Eyisisekelo)

Le nqubo, eyaziwa ngokuthi umjikelezo we-Rankine, ingahlukaniswa ngezigaba ezine eziyinhloko:

Ukukhiqiza Ukushisa: Uphethiloli ushiswa kubhoyila ukuze kukhiqizwe ukushisa okukhulu. Uphethiloli ovamile uhlanganisa:

Amalahle

Igesi Yemvelo

Uwoyela (i-Petroleum)

I-biomass (isb., izinkuni, imfucuza yezolimo)

Ukuhlukana Kwenuzi (Ama-athomu e-uranium ayahlukana, akhiphe ukushisa okukhulu esikhundleni sokushisa uphethiloli)

Ukukhiqizwa Komusi: Lokhu kushisa kusetshenziselwa ukubilisa amanzi kuma-boiler amakhulu, okudala umusi onomfutho ophezulu.

Ukujikeleza Kwe-Turbine: Umusi ocindezela kakhulu uphoqeleka ukuthi ungene ku-turbine—uchungechunge lwama-blade afakwe ku-shaft. Ukucindezela komusi kubangela ukuthi ama-blade kanye ne-shaft kujikeleze ngesivinini esikhulu kakhulu.

Ukukhiqizwa Kukagesi: Umgodi ojikelezayo uxhunywe kujeneretha. Ngaphakathi kujeneretha, amandla okujikeleza (amandla omshini) aguqulwa abe amandla kagesi ngokusebenzisa ukufakelwa kukagesi. Lo gesi ube usuthunyelwa kugridi yamandla.

Ngemva kokudlula ku-turbine, umusi upholiswa ku-condenser (ngokuvamile kusetshenziswa amanzi abandayo avela emfuleni, olwandle, noma emibhoshongweni yokupholisa) ukuze ubuye ube ngamanzi, ukuze umjikelezo uqale futhi.

Imithombo Yamandla Okushisa

Izitshalo zamandla okushisa zihlukaniswa ngomthombo wazo wokushisa:

Izinzuzo kanye nokungalungi

Ukuthatha Okubalulekile

Amandla okushisa angumgogodla wokuphakelwa kukagesi emhlabeni, akhiqiza amandla ngokusebenzisa ukushisa—ikakhulukazi ngokushisa amafutha noma ukusabela kwenuzi—ukushayela ama-turbine. Nakuba kuyindlela ethembekile neqinisekisiwe, umthelela wayo emvelweni, ikakhulukazi amafutha, uyinkinga yayo enkulu, eqhuba ushintsho lomhlaba wonke oluya emithonjeni yamandla avuselelekayo njengelanga, umoya, kanye namanzi.
