Abstract
A jet stream injection device for use in a heat exchanger of a fluidized-bed type in which a flat jet stream is injected toward a heat transmission coil of the heat exchanger from below this coil so that is runs along said cell so as to form a mixed-phase flow of a gas and solid particles around the heat transmission coil. The jet stream injection device has a net with meshes smaller than the size of the particles of a fluidized bed provided over an opening provided on the upstream side of a jet stream generating slit-shaped injection port element. The opening has a larger passage sectional area than the injection port element.
