Document Type and Number:
Japanese Patent JP2660826
Kind Code:
B2
Abstract:
The system comprises an enclosure, and device in the enclosure for supporting a fluidized bed of particulate material including fuel. There is a separating device for receiving a mixture of flue gases resulting from the combustion of the fuel and entrained particulate material and separating the entrained particulate material from the flue gases. There are three compartments disposed adjacent the enclosure, and a device for discharging the separated material from the separating device to one of the compartments. There is a device for selectively permitting the flow of the separated material from the one compartment to the other compartments, and device for passing a cooling medium in heat exchange relation to the separated material in the other compartments for cooling the material. There is a first duct connecting the one compartment to the enclosure for passing the separated material in the one compartment directly back to the enclosure, and two additional ducts respectively connecting the other compartments to the enclosure for passing the separated material from the other compartments back to the enclosure, device for introducing air into one of the additional ducts for promoting the flow of the separated material from the compartment associated with the one additional duct to the enclosure, and device for varying the flow of the air to vary the flow of the material through the one additional duct.
