    摘要： A fluidized bed boiler with a support construction for a particle separator. The fluidized bed boiler includes a bottom-supported furnace in which at least one particle separator with a support construction is in gas flow connection with an upper portion of the furnace and includes a furnace side portion, an outer portion opposite to the furnace side portion, and a conical lower portion. At least two bottom-supported downcomer pipes are in fluid connection with a steam drum and adjacent to the outer portion of the particle separator. The support construction includes a frame-like supporting member surrounding at least a portion of the conical lower portion, and an outboard portion of the supporting member is attached to the at least two downcomer pipes to support the at last one particle separator.

    摘要： A fluidized bed reactor system includes a reaction chamber comprising a circulating (fast) fluidized bed, with a first grid for the introduction of fluidizing gas, and a bubbling (slow) fluidized bed having a second grid for introduction of fluidizing gas. The second grid is mounted below the first grid. First and second interconnections are provided between the circulating and bubbling beds. Particles flow from the circulating bed through the first interconnection to the bubbling bed, and vice versa for the second connection. The interconnections are positioned with respect to each other so that the pressure and density conditions within the beds are the sole mechanisms that provide the driving force to control the flow of particles from the circulating bed to the bubbling bed. An indirect heat exchanger is located in the bubbling bed for cooling particles, and various constructions of partitions may be provided for dividing up the bubbling bed and defining the interconnections, the system and method provided being greatly simplified compared to prior art constructions.

    摘要： A whirl chamber boiler plant for generation of steam includes a combustion chamber in which the fuel is burned in a whirl within the chamber. The bottom of the chamber slopes downwardly towards an inlet through which combustion air is admitted into the chamber. Fuel and inert material are admitted into the chamber adjacent the bottom thereof. The inlet is of a size suitable for fluidizing the inert material within the chamber. Boiler tubes built within the chamber provide for removal of heat from the chamber. Preferably the inert material is a grain-shaped ash of the type produced by the burning of the fuel. In one embodiment of the present invention, a portion of the ash contained in the gases exiting from the chamber is returned to the chamber.
