  • Storage of Bulk Solids
    • In nearly every process industry bunkers and silos are used for storage and inbetween storage of granular materials and powders, usually called bulk solids. The design of an installation for this kind of industry must therefore involve a thorough attention to the storage aspects of the process. Neglecting this part has in the past too often led to unreliable systems and the necessity of sometimes radical and moneyspending changes in the installation.
      In the case of an FBC-plant we have firstly to deal with sometimes huge quantities of material (mainly coal and limestone) coming in by train, ship, truck or pipeline. These materials must be unloaded, conveyed and stored. In many cases these rough materials do not fit the demands of the FBC-furnace and need preparation and processing like breaking, sieving, drying, classification. Secondly the prepared materials must be transported to the furnace by pneumatic or mechanical conveyors, and be divided over the feeding-points. Furthermore the material from the furnace (fly-ash and bedmaterial) must be handled, stored and sometimes be prepared before it leaves the plant. This all will lead to a materials handling system which must be an integral part of the plant design.
      In general it can be said that the conveying equipment itself will not produce much problems as long as the right conveyors (type and capacity) are chosen and ample attention is given to the joints between the various parts. The know-how as available from manufacturers and literature will as a rule be an adequate base to make the right choice.
