Introduction of Thermic Lance

Daiwa Thermic Lance (TH) is a steel pipe filled with inner tube and wires and creates super high temperature and powerful flame. Thermic Lance can produce super high heat rate up to 4,000℃ with Fe + O2 → Fe2O3 + Heat reaction. It burns itself by blowing oxygen and produces high heat. The principle is to harness oxidation heat of high temperature by providing pressurized oxygen to inside the ignited steel pipe. Generally the inside of a metal tube contains steel wire that promotes combustion.
