Experiments were performed with styrene bed material to determine the influence of bed density and particle size distribution on CFB fluidization characteristics. Comparisons between the styrene data, previous data using glass bed material, and the theoretical equations for bed pressure drop and minimum fluidization show excellent agreement between theory and experiment for all cases. Laboratory preparations are underway for experiments on particle elutriation from a CFB. In addition, preliminary data were obtained on the velocity profiles in the freeboard region of a CFB. Sample profiles are presented for one set of operating conditions. An analysis of the energy costs for a CFB coal combustor operating in a combined cycle is described. When compared to energy costs for other fossil-fired power generation systems, the results indicate the CFB system has excellent potential, particularly for peak power generation applications.
