DYNAMIC SIMILARITY IN SCALING-UP FAST INTERNAL CIRCULATING FLUIDIZED BED GASIFIER
KOMUNALNA ENERGETIKA / POWER ENGINERING, 13
The article introduces research of particles dynamics in a cold flow model of FICFB (Fast Internal Circulating Fluidized Bed) biomass gasification process and its scale-up to hot industrial pilot plant. A laboratory unit has been made for the purposes of experimental research, which is three times smaller than the industrial pilot plant. Process was designed and experimentally tested on cold-flow model and scaled-up to hot industrial process. For a reliable scaling up similar flow conditions were achieved in both units. The results of the laboratory model shows as similar to those of the scale-up device if geometry, flow and Reynolds numbers are the same. Therefore, there is no need to bring an expensive full-scale gasification plant into the laboratory and actually test it. This is an example of "dynamic similarity".
