Abstract
A horizontal cyclone separator in which a furnace section and a vortex chamber communicating with the furnace section and having an inlet which extends a fraction of the length of the furnace section receives a mixture of the gaseous products of combustion and solids entrained by the gases. A coaxially disposed tube extends partially into the chamber to allow the separated gases to exit the separator. A ring-shaped solids deflector is disposed on the vertical wall opposite the coaxially disposed tube to prevent solids from bouncing off the rear wall towards the center of the separator and into the path of the separated gas stream. The separated solids fall into an outlet trough formed in a lower portion of the furnace section for returning the solids to the furnace section.
Claims5
In a fluidized bed reactor having a vessel for receiving a fluidized bed of solid particles including fuel, and a cyclone separator formed in the upper portion of the vessel by extending the walls of the vessel in a manner to form two end walls and two opposed walls, at least one of the opposed walls having a curved portion defining a generally cylindrical vortex chamber, an inlet opening connecting the vessel to the vortex chamber for introducing a mixture of the particles and gases from the vessel into the vortex chamber where the fuel particles are separated from the gases by centrifugal forces, an outlet opening formed through one of the walls in communication with the vortex chamber for discharging the gases from the vortex chamber, and a passage connecting the vortex chamber to the fluidized bed to pass the separated particles back to the fluidized bed;
- wherein the improvement comprises:
- a block disposed adjacent the inlet opening for defining an inlet passage for directing the mixture in into the vortex chamber in a tangential direction thereto.
