Kupitilira Kutentha ndi Kuziziritsa Koyambira: Mfundo Yaikulu ya Wosintha Kutentha

Pazosavuta, achosinthira kutenthaZimathandiza kusamutsa kutentha kuchokera ku madzi amodzi (madzi kapena mpweya) kupita ku ena. Madzi awa amayenda olekanitsidwa ndi khoma lolimba (nthawi zambiri chitsulo), kuteteza kuipitsidwa pamene kulola mphamvu ya kutentha kudutsa. Njirayi imapezeka paliponse:

1. Kuziziritsa: Kuchotsa kutentha kosafunikira kuchokera ku madzi opangidwa (monga kuziziritsa mafuta odzola mu injini, kuziziritsa kutulutsa kwa reactor mu chomera cha mankhwala).
2. Kutentha: Kuwonjezera kutentha kofunikira ku madzi (monga, kutentha madzi owonjezera mu boiler ya power plant, kutentha madzi asanayambe kuchitapo kanthu).
3. Kuundana: Kusintha nthunzi kukhala madzi mwa kuchotsa kutentha kwake kobisika (monga, kuundana nthunzi popanga magetsi, kuzizira mu mayunitsi a AC).
4. Kutuluka kwa nthunzi: Kusintha madzi kukhala nthunzi powonjezera kutentha (monga, kupanga nthunzi, kusakaniza njira zopangira chakudya).
5. Kubwezeretsa Kutentha: Kutenga kutentha kotayika kuchokera mumtsinje wina kupita ku wina, kukulitsa kwambiri kugwiritsa ntchito mphamvu moyenera komanso kuchepetsa mtengo wa mafuta ndi utsi woipa.

 

Chifukwa Chake Makina Osinthira Kutentha Amalamulira Machitidwe Amakampani Padziko Lonse:

Kuchuluka kwawo kumachokera ku zabwino zosatsutsika:
