Method of solid fuel combustion intensification

Abstract

The substance of the invention consists in the combustion of the fuel-air mixture in the electric field by means of the catalyst located in the combustion zone and to which high voltage is applied, which results in reduction of activation energies of all endothermic combustion phases due to the formation of oxygen atoms, carbon radicals and oxygen-containing radicals.Technical result: introduction of the catalyst in the combustion zone minimizes energy expenditure for creation of the low-temperature plasma, allows to increase the temperature in the combustion zone, to reduce activation energy of all endothermic processes taking place at the initial phase of combustion and to reduce carbon content in the ash and to achieve considerable fuel economy.

Description

BACKGROUND OF THE INVENTION[0001]The method relates to the power engineering, metallurgy, and namely, to the solid fuel combustion: coal, peat, wood.[0002]The process of solid fuel combustion is well known. So far, a considerable number of methods of solid fuel intensification are known. One of the methods consists in combustion intensification by increasing oxygen concentration in the flame, resulting in increasing of atoms and oxygen-containing radicals in the combustion zone.[0003]The method of oxygen-convector steel melting is known (see Kazakov N. F., Osokin A. M., Sishkova A. P. Technology of metals and other structural materials, 1975-688 p.). The substance of this method consists in the iron oxygen blow through the lance. During the high-temperature mass oxygen blowing oxidation of hardly oxidized additives is achieved. The highest oxidation of additives takes place at the oxygen jet-metal interface.[0004]The disadvantages consist in the use of a precious oxidizer, unproduct...
