Development of an Induction Heating Thermal Desorption Systemfor Remediation of Contaminants in Railway Infrastructure; [철도 인프라 오염 정화를 위한 유도가열 열탈착 시스템 개발]

초록

Various studies have been conducted to remove contaminants for the purpose of cleaning and/or reusing infrastructure such as contaminated soil, gravel, and wooden ties generated by railroads, and among them, the thermal desorption method has the advantage of high efficiency in removing contaminants by decomposing and evaporating contaminants at high temperatures. The thermal desorption method requires heating up to a high temperature of up to 700℃, so induction heating is more suitable than heating using fuel. In addition, a proper design considering both thermal and electronic systems is required to ensure temperature safety to prevent burnout of the induction coil and efficient energy transfer. This paper introduces a thermal desorption decomposition system, and analyzes and designs using thermal/electronic system analysis and performance analysis through manufacturing and experiments.
