Kugwiritsa ntchito

Zingaphatikizidwe ndi ma ayoni achitsulo osiyanasiyana.

Imagwiritsidwa ntchito ngati choletsa kukula kwa sikelo m'madzi ozizira komanso pochiza madzi a boiler. Imalimbana bwino ndi kutentha. Imakhalabe ndi mphamvu yabwino pa 200℃.
Ingagwiritsidwenso ntchito ngati choletsa dzimbiri, chowonjezera chopanda cyanide.
