| 摘要 |
The invention relates to a device for electrically heating a vertically erect chamber, for example, a reactor, to high temperatures (>=1000° C.) and/or with high power (30 to 1000 kW per zone), comprising several heating zones arranged vertically one above the other. The components of the de- vice, with the exception of the insulating components, are made from graphite materials. The aim of the invention is to embody and develop the device such that the largest possible degree of stability and functional capability for the whole device is achieved with low constructional complexity. The device should in particular be capable of heating very tall chambers. The above is achieved in that each zone (Z) comprises a number of supports ( 1 ), arranged in an essentially even distribution around the chamber (R) for heating, which simultaneously serve as electrical supplies for the heater, and in that the heater for each zone (Z) is arranged such as to be fixed at one end thereof and longitudinally displaceable at the other end thereof.
