A heat lance is an industrial tool that generates temperatures up to 8000°F to cut through any material. It uses iron wire and high-purity oxygen and has various applications, including removing concrete, clearing rubble, and cutting scrap.
A heat lance, also known as a flaming bar or heat lance, is an industrial tool that uses the oxidation of iron to generate very high temperatures (7000 to 8000°F, or 3.871 to 4.426°C) to cut through virtually anything including rock. The temperature generated is greater than the melting point of any known substance, with diamond having the highest at 3.547°C or 6.416°F.
Thermal lances are hollow rods filled with iron wire. High-purity oxygen is pumped into the lance and the end should be lit by a high-temperature source, such as an oxy-acetylene torch.
The thermal lance has many uses: it can be used whenever metallic or non-metallic material needs to be removed from an area or cut in half, and there is no other way. In industrial spill accidents, when molten material is spilled, it can be allowed to solidify and then cleaned up with this tool. For coastal buildings, internal concrete sometimes breaks down to produce what is called “concrete canker”. A heat lance can be used to remove this degrading concrete so that replacement material can be bagged.
In emergency situations where rubble needs to be cleared to reach trapped people, a heat lance can be used to break up larger pieces of rubble so that other machinery can remove them. For large construction equipment that have pins that can bind or bend, the spear can remove the bad pins. In high temperature furnaces, reflective tiles or spouts can be damaged by the molten material, requiring removal by heat lance.
Other applications including cutting objects for scrap and removing awkward parts of buildings, such as statues or bank vaults.
