Njira ziwiri zochizira kutentha kwachitsulo

Njira yochizira kutentha kwa chitsulo nthawi zambiri imakhala ndi njira zitatu: kutentha, kutchinjiriza, ndi kuziziritsa. Nthawi zina pamakhala njira ziwiri zokha: kutentha ndi kuziziritsa. Njirazi zimalumikizana ndipo sizingasokonezedwe.

1. Kutentha

Kutentha ndi njira imodzi yofunika kwambiri yotenthetsera kutentha. Pali njira zambiri zotenthetsera kutentha kwachitsulo. Yoyamba inali kugwiritsa ntchito makala ndi malasha ngati gwero la kutentha, kenako kugwiritsa ntchito mafuta amadzimadzi ndi a gasi. Kugwiritsa ntchito magetsi kumapangitsa kutentha kukhala kosavuta kuwongolera ndipo sikuwononga chilengedwe. Magwero otentha awa angagwiritsidwe ntchito potenthetsera mwachindunji, kapena kutentha mwachindunji kudzera mu mchere wosungunuka kapena chitsulo, kapena ngakhale tinthu toyandama.

Chitsulo chikatenthedwa, chogwirira ntchito chimawululidwa mumlengalenga, ndipo nthawi zambiri kusungunuka ndi kuchotsedwa kwa mpweya kumachitika (ndiko kuti, kuchuluka kwa kaboni pamwamba pa chitsulo kumachepa), zomwe zimakhudza kwambiri mawonekedwe a pamwamba pa ziwalozo pambuyo potenthedwa. Chifukwa chake, zitsulo nthawi zambiri ziyenera kutenthedwa mumlengalenga wolamulidwa kapena mumlengalenga woteteza, mumchere wosungunuka, komanso mu vacuum. Kutentha koteteza kumathanso kuchitika pogwiritsa ntchito njira zophikira kapena zopaka.

Kutentha kotenthetsera ndi chimodzi mwa zinthu zofunika kwambiri pa njira yotenthetsera kutentha. Kusankha ndi kuwongolera kutentha kotenthetsera ndiye nkhani yayikulu kuti muwonetsetse kuti kutentha kwabwino. Kutentha kotenthetsera kumasiyana malinga ndi zinthu zachitsulo zomwe zikukonzedwa komanso cholinga cha kutentha, koma nthawi zambiri kumatenthedwa mpaka pamwamba pa kutentha kwina kosinthika kuti pakhale kapangidwe kotentha kwambiri. Kuphatikiza apo, kusinthaku kumafuna nthawi inayake. Chifukwa chake, pamwamba pa chitsulo chogwirira ntchito pakafika kutentha kofunikira, kuyenera kusungidwa kutentha kumeneku kwa nthawi inayake kuti kutentha kwamkati ndi kwakunja kukhale kofanana komanso kusintha kwa kapangidwe ka microstructure kukhale kokwanira. Nthawi imeneyi imatchedwa nthawi yogwira. Pogwiritsa ntchito kutentha kwamphamvu kwambiri komanso kutentha pamwamba, liwiro lotenthetsera limakhala lachangu kwambiri ndipo nthawi zambiri palibe nthawi yogwira, pomwe nthawi yogwira yogwiritsira ntchito mankhwala otenthetsera nthawi zambiri imakhala yayitali.

2. Kuziziritsa

Kuziziritsa ndi gawo lofunika kwambiri pa njira yochizira kutentha. Njira zoziziritsira zimasiyana malinga ndi njira yochizira, makamaka kuwongolera kuzizira. Kawirikawiri, kuziziritsa kumakhala ndi kuzizira pang'onopang'ono, kuziziritsa kumakhala ndi kuzizira mwachangu, ndipo kuzimitsa kumakhala ndi kuzizira mwachangu. Komabe, pali zofunikira zosiyanasiyana chifukwa cha mitundu yosiyanasiyana ya chitsulo. Mwachitsanzo, chitsulo cholimba mpweya chikhoza kuumitsidwa pa kuzizira komweko monga kuziziritsa.
