MATERIALS HANDLING.

Abstract

The current world energy situation has focused attention on the dwindling supplies of fuel oil and consequently considerable attention is being given to the increased use of coal as a source of fuel. From the literature it appears that the process of feeding coal into a fluid bed combustor is still not without its problems and certainly not optimised. Although the great diffusion that exists inside the bed of this type of combustor is claimed to be a major advantage, it has its natural limitations. In order to gain both an equally distributed thermal load throughout the bed and a good combustion efficiency, it is desirable to distribute the incoming coal as uniformly as possible over the bed area.
