Ignition Tests using Electromagnetic Waves in Explosive Atmospheres

Abstract. This work investigates the process by which electromagnetic waves heat solid surfaces, potentially leading to the ignition of explosive atmospheres. Initially, the temperature increase of various lossy materials exposed to electromagnetic waves at 92 GHz is experimentally determined. Based on these observations, material samples are prepared, and ignition tests are conducted based on test specifications for small hot components in diethyl ether–air and carbon disulfide–air mixtures. These experiments provide a foundation for determining safe power limits for the application of electromagnetic waves in explosive atmospheres.
