JET STREAM INJECTION SYSTEM

摘要

The jet stream injector is for use in a heat exchanger of a fluidised-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 it runs along the cell to form a mixed-phase flow of a gas and solid particles around the heat transmission coil. The jet stream injector has a net with meshes smaller than the size of the particles of a fluidised bed provided over an opening provided on the upstream side of a jet stream generating slit-shaped injection port. The opening has a larger passage sectional area than the injection port.
