An ash discharge system has a conveyor device which transports clinker ash out of a region that is below a furnace bottom of a boiler furnace; and a separation device provided at a passage of the clinker ash from the furnace bottom to the conveyor device, the separation device including a separator which permits the clinker ash with a predetermined size or less to pass through the separator, and inhibits a large-mass clinker from passing through the separator, the large-mass clinker being the clinker ash with a size larger than the predetermined size.

A grizzly apparatus includes a plurality of grizzly bars arranged at predetermined intervals in a second direction perpendicular to a first direction which is an extension direction of center axes of the grizzly bars. Each of the plurality of grizzly bars is rotatable in a direction opposite to a direction of rotation of its adjacent grizzly bar so that a slit through which a screening target object passes and a gap through which the screening target object does not pass alternately emerge, between adjacent grizzly bars. The guide includes an outer member forming its outer shape, and has at least one guide surface inclined with respect to the second direction in such a way that the guide surface descends as the guide surface advances in the second direction toward the slit to guide the screening target object having fallen onto the guide to the slit.
