Abstract
The high-power electric heating device is capable of heating gas mixtures such as a mixture of hydrocarbons and hydrogen to temperatures and pressures attaining 900.degree. C. and 60 bar respectively. A central duct connects the gas mixture inlet to the outlet and is constituted by a plurality of superposed independently removable modules. Each module comprises a plurality of electric resistance elements formed by banks of adjacent metallic strips. A peripheral zone of the device contains power supply conductors connected to the modules. By means of passages in the form of slits between the central duct and the peripheral zone, a small fraction of the gas stream is permitted to flow within the peripheral zone.
