Abstract |
High-frequency electromagnetic radiation from radiofrequency transmitters may produce sparks on metallic constructions. At high energy the sparks are capable of igniting explosive atmospheres at gas stations or in chemical plants. The minimum spark energy required for ignition of explosive atmospheres was determined in experiments using stoichiometric mixtures of hydrogen and oxygen. A new test apparatus was used for the measurements. No significant frequency dependence in the range 10 to 70MHz was observed. The minimum spark energy of 40µJ was reported in the literature for low frequencies also. |
