Kodi mapampu otentha a geothermal amagwira ntchito bwanji?

Ntchito ya pampu yotentha ya geothermal ikhoza kufananizidwa ndi firiji, mosiyana. Kumene furiji imachotsa kutentha kuti iziziziritsa mkati mwake, pampu yotentha ya geothermal imalowa m'nthaka pansi kuti itenthetse mkati mwa nyumba.

Mapampu otentha a mpweya ndi madzi ndi mapampu otentha a madzi ndi madzi amagwiritsanso ntchito mfundo yomweyi, kusiyana kokha ndiko kuti amagwiritsa ntchito kutentha kuchokera ku mpweya wozungulira ndi madzi apansi motsatira.

Mapaipi odzadza ndi madzi amayikidwa pansi kuti pampu yotentha igwiritse ntchito kutentha kwa geothermal. Mipopeyi imakhala ndi mchere wothira mchere, womwe umatchedwanso brine, womwe umalepheretsa kuzizira. Pachifukwa ichi, akatswiri nthawi zambiri amatcha mapampu otentha a geothermal "mapampu otentha a brine". Nthawi yoyenera ndi pampu yotentha ya brine-to-water. The brine imatulutsa kutentha kuchokera pansi, ndipo pampu yotentha imasamutsa kutentha kumadzi otentha.

Magwero a mapampu otentha a brine-to-water amatha kuzama mpaka mita 100 pansi. Izi zimadziwika kuti Near-surface geothermal energy. Mosiyana ndi zimenezi, mphamvu ya geothermal wamba imatha kulowa m'magwero akuya mamita mazana ambiri ndipo imagwiritsidwa ntchito popanga magetsi.

Ndi mitundu iti ya mapampu otentha a geothermal ndi magwero ati omwe alipo?

Kuyika

Monga lamulo, mapampu otentha a geothermal amapangidwa kuti aziyika m'nyumba mu chipinda chowotchera. Zitsanzo zina ndizoyeneranso kukhazikitsa panja kuti zisunge malo mu chipinda chowotchera.

Zofufuza za Geothermal

Ma probe a geothermal amatha kutambasulira mpaka 100 metres pansi kutengera kutentha kwa dothi komanso kutentha kwanyumba. Osati gawo lililonse loyenera, monga thanthwe. Kampani yaukadaulo iyenera kulembedwa ntchito yoboola mabowo opangira ma probe a geothermal.

Monga mapampu a kutentha kwa geothermal omwe amagwiritsa ntchito ma probe a geothermal amakokera kutentha kuchokera kuya kwambiri, amathanso kugwiritsa ntchito kutentha kwakukulu ndikuchita bwino kwambiri.

Osonkhanitsa kutentha kwa kutentha

M'malo moyika ma probe a geothermal omwe amafikira pansi, mutha kugwiritsa ntchito zosonkhanitsa za geothermal. Zotolera kutentha kwa kutentha ndi mapaipi a brine omwe akatswiri otenthetsera amawayika m'munda mwanu mu malupu. Nthawi zambiri amaikidwa m'manda mamita 1.5 okha.

Kuphatikiza pa otolera wamba wa geothermal, zitsanzo zokonzedweratu ngati mabasiketi kapena ngalande za mphete zimapezekanso. Mitundu ya otolerayi imapulumutsa malo chifukwa ili ndi mbali zitatu m'malo mwa awiri-dimensional.
