Summary

The full-scale, cold-flow model testing has allowed visual review of the fluidization characteristics and the effect of immersed tubes within the bed. Thus far the three-dimensional model has shown that 1/4'' size limestone is difficult to fluidize and 1/8'' size more acceptable, bed expansion is less than predicted and the air inlet plenum design has been successfully established. Completion of the test program was hampered by repeated failures of the flexible hoses which carry the fluidized air and entrained solids to the cyclone filters. Also, several tests required rerunning due to excessive leakage of air around and between the distributor plates. The plates have been sealed to prevent by-passing of air during future tests. A tube failure analysis of the boiler circuits has indicated that a relief system must be provided in the gas outlet duct to handle excessive pressure should a double ended tube leak occur. Preliminary design related to the Demonstration Plant has continued at an increased activity level. An engineering meeting was held at Rivesville, West Virginia to discuss fluidized-bed operation. Conceptual designs of larger commercial or industrial fluidized-bed boilers are being prepared. These will be evaluated and serve as a basis for the design of the demonstration boiler design. The design of other boiler-related, auxiliary equipment and evaluation of system designs are being accomplished.
