Abstract

This paper considers an efficient approach to the combustion of water-coal fuel with minimal environmental impact. Today, a plasma system can provide high-quality ignition of water-coal fuel and accompany its combustion. The purpose of this paper is to study the plasma stimulation of carbon burn-up in coal-water fuel. To study the features of the interaction of a water-coal suspension with plasma, an electric arc plasma torch of a linear scheme with copper electrodes, operating in the air as a plasma-forming gas, was chosen. To analyze the influence of an external magnetic field on the control of the plasma jet parameters, a series of experiments were carried out using an electric arc plasma torch on a 15 kW plasma laboratory setup. It has been established that the use of an external transverse magnetic field makes it possible to intensify the process of heating water-coal fuel and burning out carbon in fuel particles. The observed intensification of the fuel gasification process is the result of the harmonization of the relative position of the plasma flow and the material being processed due to the spatial displacement of the high-temperature zone of the plasma flow towards the fuel supply. Experimental studies have been carried out on the temperature distribution along the axis of a dusty jet and the degree of mass-average carbon burnout. The averaged dependences of the particle temperature on the flow rate of the plasma-forming gas and the polarity of the magnetic field within the initial section of the jet are obtained. In a plasma-coal burner, the problem of sufficiently rapid mixing of the transversely supplied raw material and heat carrier in the minimum volume of the reaction zone has been solved. The optimization of the mixer was reduced to the choice of such a geometry (diameter and opening angle of the plasma torch nozzle channel, diameter and angles of the holes for supplying water-coal fuel with respect to the axis of the plasma torch channel), which ensures uniform distribution of the atomized fuel in the channel. The patterns obtained can be used for constructive and technological design in the creation and development of installations for the combustion of coal-water fuel.
