Abstract
  • The effects of enriching natural gas with hydrogen on local flame extinction, combustion instabilities and power output have been widely studied for both stationary and mobile systems. On the contrary, the issues of explosion safety for hydrogen-methane mixtures are still under investigation. In this work, experimental tests were performed in a 5 L closed cylindrical vessel for explosions of hydrogen-methane mixtures in stoichiometric air. Different compositions of hydrogen-methane were tested (from pure methane to pure hydrogen) at varying initial pressures (1, 3 and 6 bar). Results have allowed the quantification of the combined effects of both mixture composition (i.e., hydrogen content in the fuel) and initial pressure on maximum pressure, maximum rate of pressure rise and burning velocity. The measured burning velocities were also correlated by means of a Le Chatelier's Rule-like formula. Good predictions have been obtained (at any initial pressure), except for mixtures with hydrogen molar content in the fuel higher than 50%. (literal)
