Thermal lance

Thermal lance‏‎

A thermal lance, also known as a burning bar or thermic lance, is a tool that applies the principles of thermodynamics to cut through virtually any material, including rock, concrete, and metal. It operates by burning a combination of oxygen and iron in a steel tube at temperatures that can exceed 4000 degrees Celsius.

History

The thermal lance was first developed in the early 20th century for use in metallurgy and mining. It was later adopted by the construction industry and emergency services for its ability to cut through materials quickly and efficiently.

Operation

The thermal lance operates by burning a combination of oxygen and iron in a steel tube. The iron rod is ignited at one end, and oxygen is then fed through the tube. The resulting reaction generates intense heat, which is focused at the tip of the lance. This allows the operator to cut or melt through most materials.

Applications

Thermal lances are used in a variety of industries, including construction, mining, and emergency services. In construction, they are used to cut through reinforced concrete and steel. In mining, they are used to break up hard rock. In emergency services, they are used to cut through wreckage in rescue operations.

Safety

Operating a thermal lance requires proper safety equipment, including heat-resistant gloves, a face shield, and a fire-resistant suit. The intense heat generated by the lance can cause severe burns and eye damage if proper precautions are not taken.
