Kaarilämmittimiä

Kaarilämmittimiä, known in English as arc heaters, are devices that utilize an electric arc to generate heat. This process involves passing a high-voltage electric current through a gas, creating a plasma that emits intense heat and light. The heat generated by the arc can be harnessed for various industrial and scientific applications.

The fundamental principle behind kaarilämmittimiä is the ionization of a gas. When a sufficient voltage is applied across two electrodes, the gas between them breaks down, forming a conductive plasma. This plasma is extremely hot, reaching temperatures of several thousand degrees Celsius. The energy of the arc can be controlled by adjusting the current and voltage, as well as the type and pressure of the gas used.

Common applications for kaarilämmittimiä include metal melting and refining, welding, cutting, and surface treatment. They are also used in research laboratories for high-temperature experiments and in specialized industrial processes where extremely high temperatures are required. The efficiency and controllability of arc heating make it a valuable technology in many fields. The design of kaarilämmittimiä can vary depending on the specific application, but they typically consist of electrodes, a power source, and a system for introducing and containing the gas. Safety considerations are paramount due to the high temperatures and electrical power involved.
