The effects of gas-solid nonequilibrium on various aspects of forced filtration combustion (FC) waves were determined. Conductively driven coflow FC waves were studied using one-temperature models. It was known from one-temperature model analyses that extinction of steady traveling waves will occur if the gas influx is sufficiently large. The results show that thermal nonequilibrium has a significant effect on the intrinsic extinction limit and the combustion characteristics.
