<p>Device comprises a chamber for heating gases, in which at least four heating elements (11) or four groups of heating elements made of an electrically conductive material are located, where each heating element or each group of heating elements are connected to a separate regulating and/or controllable subsystem of an electrical power network, and are heated by direct passage of current. At least four regulating and/or controllable subsystems are galvanically isolated from ground. Device comprises a chamber for heating gases, in which at least four heating elements (11) or four groups of heating elements made of an electrically conductive material are located, where each heating element or each group of heating elements are connected to a separate regulating and/or controllable subsystem of an electrical power network, and are heated by direct passage of current. Each separately regulated and/or controllable heating element or each separately regulated and/or controllable group of heating elements are supported based on same or different value of a parameter including temperature, heating power, current, voltage or resistance, or can be influenced by the device process size of the heating element to be controlled or regulated, where at least four regulating and/or controllable subsystems are galvanically isolated from ground. An independent claim is also included for thermal treatment of corrosive gases.</p> |
