A numerical analysis model was developed for predicting the behavior of dual‐component, refractory‐lined coal‐gasification vessels. The temperature‐dependent constitutive law, failure criteria, creep behavior, thermal expansion contraction behavior, and shrinkage characteristics of refractory concrete were formulated. To verify the proposed model, a three‐dimensional simulation analysis was made of an experimental gasifier vessel. The model was then used to study parameters on a circular, dual‐component, refractory concrete‐lined coal‐gasification vessel. The effects of shrinkage, creep, temperature distributions, vessel shell temperatures, bond barriers and anchor spacing, size, and shape on the performance of the gasifier vessel were studied. Design recommendations are made to aid in improving the mechanical reliability of refractory concrete‐lined coal‐gasification vessels.
