Abstract
A monitoring device for continuously monitoring the internal circulation flow-rate of solid particles in a circulating fluidized bed reactor including a bottom zone into which the fluidization gas is injected and a top zone surrounded by walls. The device includes a sampling tank for sampling internal circulation of solids, which tank is fixed against one of the walls of the reactor and is provided with a fluidization device. A removal pipe is provided for removing the solids from the tank and conveying them to a measuring device for measuring the flow-rate of the solids. A return pipe is provided for returning the solids from the measuring device to the inside of the reactor.
