The properties of fluidized beds can be drastically altered by the insertion of various types of internal structures. These include screens of all types and orientations, baffles both horizontal and vertical, and heat transfer surfaces. Experimental studies of certain of these internals have been carried out at UMR with the aim of improving the quality of the fluid bed. By improved quality is usually meant smoother, better controlled fluidization, minimized slugging, improved gas-solid contacting, increased or smoothed heat or electrical conduction, and control of the solids movement pattern.
What has been learned at UMR, particularly with difficult to fluidize materials, and other data in the literature is applied in this paper to considerations of the design of fluidized bed coal gasifiers. Implications to several gasifier design types are discussed. Recommendations for future research work related to fluidized coal gasifier design are presented with regard to the needs of each design type.
