Abstract

A plasma generator with a liquid cathode has been developed and investigated, which makes it possible to create a plasma flow from electrolyte vapors with a temperature of up to 1800°C with a mass flow rate of up to 3.0 g/s for the gasification of carbon-containing waste. An electrolyte in the form of a solution of Glauber salt in distilled water with a concentration of 0.5-1.0 kg/m3 by weight was used. The current-voltage characteristics of the discharge are constructed. The optimal electrical and thermal parameters of the plasma flow are determined experimentally.

Highlights

  • There is an acute shortage of energy resources

  • The use of superheated water vapor as a plasma-forming medium creates a number of technical problems that reduce the reliability and service life of power plants

  • Plasma generation by means of a liquid cathode discharge has a number of advantages in comparison with the electric arc method

Summary

Introduction

There is an acute shortage of energy resources. Deposits of hydrocarbon raw materials are depleted, and their cost periodically increases. The use of superheated water vapor as a plasma-forming medium creates a number of technical problems that reduce the reliability and service life of power plants. Plasma generation by means of a liquid cathode discharge has a number of advantages in comparison with the electric arc method.
