GRIZZLY DEVICE AND MAIN ASH DISCHARGE SYSTEM

A grizzly apparatus comprises 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; and at least one guide provided above the plurality of grizzly bars and extending in the first direction. 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 a reinforcement member provided in a space formed by the outer member and allowing the outer member to have a stiffness for keeping its 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.
