Investigation of the possibility of igniting coal dust using intermetallic radiation burners

Burner devices made of porous materials (radiation porous burners) are an innovative technology in which most of the fuel energy is converted into electromagnetic radiation energy in the infrared region of the spectrum in order to convert it into other types of energy: thermal, electrical, chemical. The possible prospects for the introduction of radiation porous burners into burner devices for igniting coal dust are due to the localization of the ignition point of the pulverized coal mixture, in which there is no movement of the core of the torch, a decrease in its pulsation is observed. The paper presents the results of experiments on the ignition of coal dust using porous burner devices.
