    Abstract

    To understand the hydrodynamic behaviour of a circulating fluidised bed (CFB), a cold CFB test rig with symmetrical arrangements of six cyclone separators on the top of the boiler, three separators in each side has been built and the characteristics of solid distribution in the standpipe of cyclone are investigated by electrical capacitance tomography (ECT). The objective of this research is to investigate the cold gas-solids distribution among the six cyclones by ECT measurement and compared with pressure-drop measurement. The experiment result includes the effect of uidisation velocity and boiler load (initial material weight) on the solids flux through the inlet of cyclones. The preliminary experiment result demonstrates that the three cyclone separators have different solids distribution along one side of the CFB. The analysis results will be used to scale up a CFB boiler from small scale to large scale, i.e., super-pressure circulating fluidised bed with multi-cyclone separators.
