R D for the storage, transport, and handling of coal-based fuels
The product of several advanced physical coal cleaning processes is a dry, ultrafine coal (DUC), in the order of 10 microns mean mass diameter. Cost-effective, environmentally safe systems must be provided for the storage, transport, and handling of this finely divided form of fuel. The objective of this project is the development of total logistics systems for DUC, including experimental verification of key features. The systems to be developed will provide for safe, economic, and environmentally protective storage and delivery of DUC for residential, commercial, and industrial uses. This quarter, preliminary operational testing of the Residential Tank is in progress using 158 micron methyl methacrylate particles. Detail design drawings were completed for the pressure vessels and their internals for the testing of the Industrial/Commercial Storage System. Explosibility and ignition characteristics of the four dry, ultrafine coals being tested have been completed. The cleaned, dry-ultrafine coal samples were somewhat more reactive than the reference coal. A design for a pressurized bulk tank with pneumatic loading and unloading has been identified for transportation. Flow characteristics of the DUC are being determined by the following techniques: Tap to aerated density ratio, fluidization, bed collapse, shear stress, and flow from an orifice. 17 figs., 4 tabs.
