THE INFLUENCE OF GAS RECIRCULATION THROUGH A PLASMATRON ON THE ENERGYEFFICIENCY OF A PLASMOCHEMICAL PROCESS

The increase in degree of conversion of a substance during plasma proc essing is often achieved by increasing the energy input into a dischar ge, thus leading to an increase in power consumption. This effect can be decreased if the high energy input is provided by successive contri butions of small quantities of energy in several steps, for example, u sing gas recirculation through a plasmatron. The influence of the reve rse reactions can be diminished by partial isolation of the products a fter each stage. The test experiments were performed on a high-power m icrowave-plasma processing unit.
