ABSTRACT:
The specification describes a wall arrangement for heated chambers in which arrangement the walls are provided with gaps between sections of them enabling expansion of the walls when the temperature of the chamber is increasing. The particular arrangement further provides means for preventing inert material packing said gaps so as to prevent expansion of the walls. The invention is of particular use with wall arrangements housing fluidized beds in which the inert particulate material forming the bed may enter the gap between the wall sections. As described the means for preventing the inert material packing the gaps comprises gas injector means arranged to force gas into each gap and thereby keep any inert particulate material that may enter the gap in a fluidized state.
