Most safety characteristics published so far are valid for specific and limited conditions. No explosion characteristic exists for synthesis gas which cover all conditions occurring in “real life” and resulting conditions. This requires more information and systematic investigation of the explosion parameters of synthesis gas in air under various conditions. The paper presents the results of an experimental evaluation of the safety characteristics for synthesis gas multi-component (CO-H2-CH4-C3H8)-O2-(CO2-N2) mixture at temperatures of 323 K, 373 K and 423 K and at elevated pressures of 0.50 bar, 0.75 and 1.00 bar.
