摘要: Abstract The pressure history in the explosion syngas/air mixtures with H 2 O addition over a wide range of equivalence ratios at elevated temperatures was recorded to study characteristics constant volume confined vessel. CO mole fractions syngas are from 0.5 0.95, initial 373 K 473 K, and 0 30%. parameters such as pressure, time, maximum rate rise, deflagration index obtained experiment. Effects ratio, temperature, CO/H ratio dilution on examined. These important input properties for evaluation hazards design combustion In addition, adiabatic is also calculated assuming flame propagation constant-volume process. Results show experimentally determined normalized different trends increase ratio. experimental decreases but increases mixture. This mainly because heat loss larger mixture higher At last, during process by difference between pressure. With mixture, amount transferred wall unit area greatly.
