Investigation of heat transfer and combustion in the Advanced Fluidized Bed Combustor (FBC). Technical progress report, April 1995--June 1995
This technical report summarizes the research performed and progress achieved during the period of April 1, 1995 to June 30, 1995, The particle flow measurements on mass flux of radial directional were conducted and discussed. The particle dispersion is dense near the wall and relatively dilute in the core region. It was found that the particle mass flux generally increases along the radial direction adjacent to the wall of the test chamber. An interface at a certain radius adjacent to the chamber wall is expected where interacting forces are dynamically balanced. The dense suspension layers and the dilute suspension regions were observed in the freeboard of the exploratory cold model (6 inches I.D.). Based upon observations and measurements, the general behavior of suspension layers was summarized in this report. The bench-scale advanced FBC test chamber (10 inches I.D.) was designed and fabricated to better understand how gas recirculating flow, particle suspension flow, and particle elutriation rate are affected by swirling flow in the freeboard of the test chamber. The measurements of the gas and particle flows will be conducted in this bench-scale model.
