LABORATORY AND INDUSTRIAL STUDIES OF GAS COAL IGNITION AND COMBUSTION USING HIGH-VOLTAGE ALTERNATIVE CURRENT PLASMATRON

ABSTRACT
This paper presents experimental studies and industrial applications of a promising method for igniting and combusting coal fuel using a high-voltage alternative current plasmatron. Experimental studies were carried out at a set-up with a thermal capacity of up to 5 MW. Kuznetsk long flame coal selected after a ball-drum mill with sieve residue R90 = 15%, was taken as an experimental sample. The first experimental data on implementation of the combustion process have been obtained. Introduction and first industrial tests of the high-voltage alternative current plasmatron were carried out using a real power boiler TP-10 with an output capacity of 220 tons of steam per hour with gas and fuel oil replacement by coal during the process of boiler start-up.
