Gasification reactor comprising a pressure absorbing compliant structure

A reactor for gasification of feedstocks for gasification, adapted to handle feedstocks for gasification comprising organic and inorganic compounds, wherein said compounds during gasification in the presence of oxygen and/or air at a gasification temperature, wherein the melting temperatures of the constituent inorganic compounds is at least 100° C. lower than the gasification temperature, are converted to a hot reducing gas above 950° C. but below 1300° C. and comprising CO, CO2, H2 and ¾0 (g), and a salt melt, wherein said reactor comprises an outer reactor shell and an inner refractory lining, wherein a compliant structure is placed in a ring-shaped coaxial expansion space between said outer reactor shell and said inner refractory lining, wherein said compliant structure has a resilience and comprises a plurality of substantially parallel arranged metal profiles, adapted to distribute the compressive load between said reactor shell and the inner refractory lining in that the metal profiles are positioned such that they form substantially parallel, pressure-absorbing bridges, wherein said profiles are elastically deformed in a first compression interval (ΔY1) and plastically deformed in a second compression interval (ΔY2).

A method for manufacturing and disposing a compliant structure between a reactor shell and an inner refractory lining in a gasification reactor, characterized in that said compliant structure comprises one or several hollow metal profiles, said profile/profiles being fixed to a metal sweep, preferably having approximately the same plate thickness as said profile/profiles, whereby a section of profiles on a metal sweep is formed, and are joined, preferably welded together, into a continuous, compliant structure, wherein the profile side of the sections is pointed outwardly towards the reactor shell.
