✦ Synopsis

Heat transfer analysis was used to evaluate conceptual models of processes associated with In Situ Vitrification (ISV). ISV is a phase-change process used to melt contaminated soil sites into more stable configurations for environmental restoration. Using data from a field-scale ISV test we develop relations that allow us to estimate the temperature of the melt from voltage and amperage measurements. The calculated temperatures are in excellent agreement with measured values. A global heat balance calculation is used to account for heats of several processes that occur as soil is heated up and melted during ISV. This analysis yields an efficiency of 33% for the ISV process. Most of the heat is lost from the surface of the melt, and heat transfer concepts confirm that radiative heat transfer is the dominant process.
