Prediction of Pressure Profile and Particle Circulation Rate in a Fluidized Bed Gasifier with Triple-beds and Dual Circulation

Abstract

The pressure profile and particle circulation rate in a fluidized bed gasifier with triple-beds and dual circulation were clarified by operating a cold model, which is the capacity of 10kg/d. As a result, the operation of the gasifier was stable. The predicted pressure profile in the gasifier qualitatively corresponded to the measured pressure profile. The particle circulation rate increased with increasing pressure drop in the riser, which is the pressure difference between riser and cyclone inlet.
