Pressure fluctuations are one of the most important parameters in the design and operation of gas-solid circulating fluidized bed (CFB), whose signals reflect lots of nonlinear hydrodynamics behaviors in the bed.
For sand, glass bean, quartz sand and PVC, pressure fluctuations were measured at different conditions. Furthermore, statistics analysis, power spectral density (PSD) analysis and chaos analysis of pressure fluctuations in gas-solid CFB were conducted.
