Abstract |
The report gives results of an experimental investigation of a pulsed, dense-phase pneumatic transport system for controlled circulation between adjacent fluidized beds. A model was developed to predict performance. The program provides technical support for EPA's program to demonstrate the Chemically Active Fluid Bed (CAFB) Process, being developed to produce a clean, low heating value fuel gas from fossil fuels. A cold model test facility, capable of transporting up to about 6.3 kg/s, was built and operated to demonstrate effects of key parameters. Generated data were utilized in the development of a mathematical model of the system which allows projection of the effects of key variables. Solids flow is controlled by pulsed air input, whose on-time(<0.3 to 0.4s) and off-time (1.5 to 2.0s) should be controlled for best performance. The system pressure balance should also be carefully controlled. Expected demonstration plant bed-material density may result in higher air requirements than was predicted in the plant design. Wider legs and more nozzles or greater transport-gas capacity may alleviate this difficulty. |
