Title: A Fluid Dynamics Study Of A Circulating Fluidized Bed With Secondary Air Injection
Author: Pecora A.A.B.
Goldstein Jr. L.
Abstract: This paper presents an experimental study on the fluid dynamics of a circulating fluidized bed with secondary air injection. The experiments were run in a 4 m high, 100 mm internal diameter riser system. The solid material was 200-920 μm diameter sand. The gas temperature at the beginning of the riser was around 200°C and the superficial gas velocity varied in the 2.5-9.5 m/s range. The data obtained made possible to suggest correlations for the pressure drop in a cyclone and in a recirculating L-valve, which are necessary to study the system pressure balance. The pressure profiles in the loop of the circulating fluidized system show the secondary air injection influence.
