Measurement Of Ignition Delay Time For A Syngas/Air Mixture Containing Water Vapor

Abstract

Ignition delay times of syngas mixtures containing water vapor are of interest to the gas turbine industry because water is often a non-negligible constituent of syngas. This paper presents ignition time data from shock-tube experiments obtained for three mixture compositions, two with water, fuel, and air and one with just fuel and air. The experiments were performed in the intermediate temperature range (950-1400 K) and at pressures around 1.5 atmospheres. The fuel-to-air equivalence ratios were 1.0, 0.9 and 1.0 for the no-water, 50/50% fuel/water, and 87/13% fuel/water blends, respectively. The results were then compared with a modern kinetics model. There was good agreement between the model and the data at the pressures and temperatures of the present experiment, particularly at the highest temperatures where the kinetics are dominated by H + O2 = OH + O branching kinetics.
