Abstract

Power-supply circuits for electrothermal gasification of carbon-containing solid materials are considered. Mathematical models and experimental studies have made it possible to determine the main parameters of three- and six-electrode units having a higher electrical efficiency and power factor, and are appropriate for graphitized electrodes, which are simpler and more reliable in operation. The effect of different power-supply circuits for multielectrode units on the resistance and electric field of the baths is studied. It has been found that symmetric multiphase power-supply circuits with a minimum phase difference between the potentials of adjacent electrodes are most efficient for the case of multielectrode furnaces.

摘要

考虑了用于电热气化含碳固体材料的电源电路。数学模型和实验研究使得确定具有较高电效率和功率因数的三电极和六电极单元的主要参数成为可能，并且适用于石墨化电极，其操作更简单，更可靠。研究了多电极单元的不同电源电路对熔池电阻和电场的影响。已经发现，对于多电极炉来说，在相邻电极的电势之间具有最小相位差的对称多相电源电路是最有效的。
