BIOMASS BUNKER, AND BOILER PLANT COMPRISING THE SAME

To provide a biomass bunker capable of preventing degradation of biomass fuel resulting from rapid combustion and water absorption of stored biomass fuel, and a boiler plant comprising the same.SOLUTION: A biomass bunker 31 comprises a bunker body 51 that stores biomass fuel, a humidity monitor 52 that detects the humidity in the bunker body 51, a two-fluid nozzle 53 that sprays a mixed fluid of water and air, a water feed pipe 54 and an air feed pipe 55 each connected to the two-fluid nozzle 53, a flow control valve 56 attached to the water feed pipe 54, an on-off valve 57 attached to the air feed pipe 55, and a control panel 58 that controls switching of the flow control valve 56 and the on-off valve 57. The control panel 58 switches the flow control valve 56 and the on-off valve 57 to an opened state from a closed state upon determining that a value of humidity detected by the humidity sensor 52 is lower than a set value set in the control panel 58.SELECTED DRAWING: Figure 1 【課題】貯蔵されたバイオマス燃料の急速燃焼及び吸水によるバイオマス燃料の変質を防止可能なバイオマスバンカと、これを備えたボイラプラントとを提供する。【解決手段】バイオマスバンカ３１は、バイオマス燃料を貯蔵するバンカ本体５１と、バンカ本体５１内の湿度を検出する湿度監視計５２と、水と空気の混合流体を噴霧する二流体ノズル５３と、二流体ノズル５３に接続された水供給管５４及び空気供給管５５と、水供給管５４に備えられた流量調節弁５６及び空気供給管５５に備えられた開閉弁５７と、流量調節弁５６及び開閉弁５７の切換を制御する制御盤５８と、を備える。制御盤５８は、湿度監視計５２の検出値が制御盤５８に設定された設定値を下回ったと判定したとき、流量調節弁５６及び開閉弁５７を閉状態から開状態に切り換える。【選択図】図１
