摘要： A centrifugal separator for separating particles from gas uses a separator chamber having an upper potion with at least three substantially vertical planar walls with perpendicular inner faces, and a lower portion, for defining in the chamber a vertical gas vortex. The gas vortex has an inlet formed in the vicinity of a first corner between the first and second walls for gas to be dedusted, an outlet for dedusted gas, and an outlet for separated particles. The separator uses an acceleration duct with a first transverse section at the first end of the duct that is distinctly greater than a second cross section at the second end. This second end is connected to the inlet for gas to be dedusted at the first corner.

摘要： The circulating fluidized bed reactor device comprising a reactor chamber delimited horizontally by walls, a centrifugal separator and a back pass for heat recovery The reactor device allows for the introduction of a fluidizing gas into the reactor chamber and for maintaining a fluidized bed of particles in said chambers. The gas to be dedusted is transferred from the reactor chamber into the separator, and the separated particles are discharged from the separator and the dedusted gas is transferred from the separator into the back pass. The reactor chamber and the separator both have a common wall with the back pass.

摘要： A heat exchanger system includes a first heat exchanger followed by a second heat exchanger disposed in a dense fluidized bed, the second heat exchanger being made up of a plurality of nests of tubes disposed along the path of the particles in suspension in the dense fluidized bed. The second heat exchanger is provided with at least two feeds situated on either side of its center, each of the feeds receives a distinct mixture of the input fluid and of the output fluid of the first heat exchanger, so that the temperature of the fluid fed into each of the nests is an increasing function of the distance between it and the inlet via which the particles are fed into the dense fluidized bed.

摘要： A cyclone separator that collects entrained solid particles from a gas stream, comprising a cylindrical body, an inlet duct connected to the body, and a gas outlet tube connected to the body at its upper end. The ratio of the distance between the parallel to a face dropped from the tip of the cyclone separator and the closest point of the gas outlet tube to the internal diameter of the body is at least 0.1, as measured at the lower extremity of the gas outlet tube. The ratio of the inlet duct area, measured at the tip of the cyclone separator and perpendicularly to the face, to the cross-sectional area of the body, is between 0.24 and 0.32. The ratio of the height of the inlet duct to the width of the inlet duct at the tip of the cyclone separator does not exceed 4.
