1. Kutentha kwa chitoliro chachitsulo chozungulira kumakhala ndi kutentha kofanana pamtanda ndi kutalika kwa chopanda kanthu;
2. Kutentha kwachitsulo kuyenera kukwaniritsa zofunikira zogubuduza;
3. Kutentha kwa ng'anjo yachitsulo yozungulira chitsulo kumakhala ndi ngozi zochepa ndipo kumakhala ndi moyo wautali wautumiki;
4. The ozungulira zitsulo chitoliro Kutentha ng'anjo ali zabwino luso ndi zachuma zizindikiro;
5. Kuchepetsa makutidwe ndi okosijeni ndi decarburization zitsulo ndi kupewa kutenthedwa ndi kuwotcha;
