Experimental Study of Gas Explosions in Hydrogen Sulfide-Natural Gas-Air Mixtures
From bottom: tests 32, 31, and 33. Comparison of pressure records from channels 4 and 5. Lean, stoichiometric, and rich 5% H2S/95% NG-air mixtures. Pressure is shown on the left vertical axis, while the equivalence ratio is given on the right vertical axis.
