Abstract
Provided is a solid fuel pulverizing device (100) provided with: a ventilation unit (30) configured to ventilate an interior of a housing (11) with primary air for supplying a solid fuel pulverized by a roller (13) to a classifier (16); a pressure detector (50) configured to detect an internal pressure of the housing (11) relative to a reference pressure; a flow rate detector (60) configured to detect a flow rate of the primary air blown into the interior of the housing (11) by the ventilation unit (30); and a controller (40) configured to perform control and transition the solid fuel pulverizing device (100) to a stopped state upon the internal pressure detected by the pressure detector (50) being a predetermined pressure or higher and the flow rate of the primary air detected by the flow rate detector (60) being a predetermined flow rate or less.
