The possibility of separation of the water-steam plasma in a centrifugal force field of a vortex stream is under consideration. We obtained the formulas to compute the radial distribution of the plasma mixture components and also to determine the dependence of the pressure and its gradient on the distance to the axis for the regions of solid-state and potential rotation of the vortex.  The examples of poor arc stabilization and the proposals for its perfection are presented. The effect of the gas kind on the voltage of the vortex-stabilized arc is shown. The influence of the water-steam plasma individual components, regarding the separation, on the water-steam plasma energy characteristics is explained.
