Thermal blanket

A thermal blanket is a device used in thermal desorption to clean soil contamination. The primary function of a thermal blanket is to heat the soil to the boiling point of the contaminants so that they break down. A vacuum pulls the resulting gas into a separate air cleaner that may use various methods, such as carbon filters and high-heat ovens, to completely destroy the contaminants. Aside from evaporation and volatilization, the contaminants may also be removed from the soil through other mechanisms such as steam distillation, pyrolysis, oxidation, and other chemical reactions.
