石分離装置。 In a fluidized bed boiler that burns coal while fluidizing the fluidized medium in the combustion chamber and the coal supplied to the combustion chamber by the air supplied to the combustion chamber, a pebble separation cylinder having a funnel-shaped pebble discharge port at the lower end is used. A discharge pipe is attached to the combustion chamber and discharges the fluid medium in the combustion chamber to the center of the upper part of the pebble separation pipe, and a porous hole is provided between the open end of the discharge pipe on the pebble separation pipe side and the pebble discharge port. An umbrella-shaped pebble separation screen is provided, and a part of the combustion air is introduced into the lower end of the pebble separation cylinder, and the upper end of the pebble separation cylinder and the inside of the combustion chamber are reduced to a fluid medium. A pebble separator for a fluidized bed boiler characterized by being connected by a cylinder.
