Electrothermal Fluidized Bed Technique Using for Realization of High-Temperature Technological Processes (Review)

Abstract

When implementing a number of high-temperature processes with heat supply to the reaction zone (allothermic processes), it is impossible or economically inexpedient the burning of fossil fuels to achieve the required temperature level. The possibilities of these processes implementation through the use of electrothermal fluidized bed (ETFB) techniques are considered. Such processes include, for example, the production of hydrogen by the pyrolysis of hydrocarbon gases, the production of silicon carbide and other carbides, the production of artificial graphite and the thermal purification of natural graphite, the high-temperature heating of gases and gas mixtures. These processes can be carried out in the temperature range of 600–3000 °С using fine-dispersed materials or directly in the gas phase using ETFB. In a number of processes ETFB technology can be applied as a source of high temperature gas production, used either for the implementation of this technological process, or for ensuring the operation of technological or heat engineering equipment. Also considered the main structural characteristics of the equipment that ensure the implementation of processes in the ETPS. Bibl. 37.
