The present invention relates to an apparatus for discharging bottom, which comprises: a discharge chamber for receiving the bottom ash made in a furnace where a fuel combustion occurs; a plurality of first discharge ducts formed to reduce down in size in a first direction and a second direction that are perpendicular to each other; and a plurality of second discharge ducts with one side connected to the first discharge ducts and the other side connected to the discharge chamber. Also, the present invention relates to a circulating fluidized-bed boiler having the apparatus for discharging bottom ash. According to the present invention, by increasing the size of an inlet of the first discharge duct to discharge the bottom ash from the furnace, the work for discharging the bottom ash can be easier even if the bottom ash is made from a fuel such as biomass, which produces the bottom ash with a large size resulting from adhesion to one another, and it is possible to discharge the bottom ash using force of gravity. Thus, the manufacturing and operating cost can be reduced. |
