Claim:
1. A refractory wall comprising: a refractory hotface layer comprising a hotface surface configured to be adjacent to a carbonaceous gasification environment; a backing layer facing and disposed around the refractory hotface layer to improve the mechanical strength of the refractory hotface layer, wherein the refractory hotface layer and the backing layer comprise chromium-containing materials; a cooling layer facing the backing layer and positioned between the backing layer and a compressible layer, the cooling layer configured to cool the refractory hotface layer via the backing layer; the compressible layer facing and disposed around the cooling layer and configured to provide buffer for thermal expansion of the refractory hotface layer, the backing layer, and the cooling layer; and a slag layer deposited on at least a part of the hotface surface of the refractory hotface layer.
