Decomposition and Statistical Analysis of Bulk Density Levels of Dense Phase Flyash Powder Flow within a Pneumatic Conveyor
The material pulse flow structure within the fluidized dense phase pneumatic conveying of flyash powder was studied using the Electrical Capacitance Tomography (ECT). Decomposition of the bulk density levels within the pipe cross-sectional area were obtained and statistical analysis of bulk density waves were performed. The results suggest that the pulse amplitude and duration obeyed the Weibull and lognormal distributions. In addition, bulk density factor was found to have a linear relationship with pulse amplitude; however, it is independent of pulse duration.
