Thermal Conduction Heating for In-Situ Thermal Desorption of Soils

In remediation applications, it is sometimes referred to as in situ thermal desorption (ISTD). ISTD has been used in various modes, including surface heating with blankets, subsurface heating with an array of vertical heater/vacuum wells, and ex situ blankets. Radiation heat transport dominates near the heaters, which are operated at 800 to 900°C. However, thermal conduction accounts for most of the heating at greater distances into the soil.
