負荷が大きくなる。2. Description of the Related Art As a method for reducing the volume of organic chlorides such as vinyl chloride and PCB generated from various industrial fields, it has been attempted to incinerate them in an incinerator, but most of them are for the following reasons. The reality is that it has not been put to practical use. Incineration produces a high concentration of hydrogen chloride gas (some of which may contain chlorine gas), which cannot be released into the atmosphere as it is in order to prevent air pollution. Since these hydrogen chloride gas or chlorine gas is extremely corrosive and significantly damages the refractory and metal parts of the incinerator equipment, maintaining the incinerator equipment sound for a long time is
Even if a high-quality material is used, it is difficult. Organic chlorides are essentially flame retardants because they contain chlorine, and generate a large amount of soot during incineration, which increases the load on exhaust gas treatment equipment.
