Abstract:
1. A method for the thermal treatment of corrosive gases, wherein gases contained in a chamber are heated by at least four heating elements or four groups of heating elements comprising an electrically conductive material, wherein each heating element or each group of heating elements is connected to a separately regulatable and/or controllable subsystem of an electrical energy network, wherein each heating element or each group of heating elements is regulated and/or controlled separately and is heated by direct current flow, wherein each separately regulatable and/or controllable heating element or each separately regulatable and/or controllable group of heating elements is controlled or regulated with respect to at least one either identical or different value of a parameter selected from the group consisting of temperature, heating power, current, voltage and resistance or with respect to another heating element process variable, which can be influenced by the device, and wherein at least four regulatable and/or controllable subsystems are DC-isolated from ground potential and from one another.
