摘要: Self-sustained oscillations of fluidized bed have been considered, as well the concerted periodic change in their integral parameters, including average porosity and height, flow rate a fluidizing agent, pressure drop across apparatus. The main factors are revealed, joint effect which at certain combination system parameters results development occurrence this phenomenon. Mathematical models formulated for four reactor schemes, i.e., open closed devices with blowing that blow suction gas. Solutions obtained form damped undamped finite amplitude. An analysis stability stationary solutions has carried out. Calculations performed conditions experiments known from literature. comparison calculated measured values frequencies presented.
