FLUIDIZED-BED TYPE COMBUSTION EQUIPMENT AND METHOD FOR SUPPLYING FLUIDIZED MEDIUM TO FLUIDIZED-BED COMBUSTION FURNACE

摘要

Fluidized-bed type combustion equipment (1) is provided with: a fluidized-bed combustion furnace (21) in which fuel is burned while a fluidized medium is made to flow; and a supply section (3) for supplying the fluidized medium to the fluidized-bed combustion furnace. The supply section (3) is provided with: a blower unit (32) for blowing gas used to transport the fluidized medium; and a flow velocity-adjusting part (34) for adjusting the flow velocity of the gas. The flow velocity-adjusting part (34) adjusts the flow velocity of the gas used to transport the fluidized medium, such that damage to a pipe (L33) through which the fluidized medium flows is suppressed. Because the flow velocity of the gas is decreased, the damage progression of the pipe can be suppressed.
