Experimental studies of ignition of a 5 MW semi-industrial installation in Ekibastuz coal using electrochemical activation technology

Abstract

This work uses a high-frequency electrochemical ignition device that generates high-frequency cold plasma arcs that ionize the oxidizer, which contributes to the multiple acceleration of thermochemical transformations of carbon-containing solid fuels and wastes, and, consequently, to a more complete rapid burning out of the torch. Coal fuel research was carried out at the CDPP-2 station in the city of Ekibastuz, and experiments were conducted on the ignition and combustion of coal fuels using a high-frequency electrochemical ignition device. After the coal fuel was supplied to the street swirler, the combustion chamber was heated for 4 minutes, after reaching 500 ° C, the coal burned in the autothermal regime. These results will be used to design a pilot burner at the station in Ekibastuz, Kazakhstan.
