Explosion characteristics of water gas for Fischer-Tropsch process

Abstract

Experimental study is presented for different CO-air and H-2-air mixtures at a maximum concentration range. CO concentration ranges from 12.5 +/- 0.2 % vol. to 70.5 +/- 0.2 % vol. and H-2 concentration ranges from 4.5 +/- 0.2 % vol. to 76.0 +/- 0.2 % vol. in a mixture with air at ambient atmospheric pressure (1 bar) and temperature (25 degrees C). The explosion parameters of explosion pressure and maximum rate of pressure rise for water gas-air mixture were measured within the studied range, i.e. 0.30-2.13 at temperature of 25 degrees C and pressure of 101 kPa. The experimental values of the maximum explosion pressure is compared with the mathematical modeling of this gas. The influence of initial concentration on the explosion characteristics were discussed.
