[0023] It should be noted that during the incineration of hazardous waste, the high temperature environment inside the incinerator is crucial to achieving complete incineration of waste and reducing the emission of harmful substances. However, this high temperature environment places extremely high demands on the equipment and materials of the incinerator. In addition to requiring the equipment materials to have excellent high temperature resistance, the thermal insulation performance of the furnace structure is also a key factor that cannot be ignored; the quality of the thermal insulation performance directly affects the heat loss, incineration efficiency and thermal radiation impact of the incinerator on the external environment.
