PROBLEM TO BE SOLVED: To provide a boiler system which can properly protect a heat exchanger buried in a heat transfer medium during an emergency stop.SOLUTION: A boiler system 100 includes a heat exchanger 22 in which a fluid conducting heat exchange with a heat transfer medium W flows. The heat exchanger 22 is buried in the heat transfer medium W heated by a furnace 3. Further, the boiler system 100 includes a removal part 24 which removes the heat transfer medium W from a periphery of the heat exchanger 22 during an emergency stop at which at least flow of the fluid in the heat exchanger 22 decreases or stops. Thus, even if the flow of the fluid in the heat exchanger 22 decreases or stops during an emergency stop, the heat transfer medium W is removed from the periphery of the heat exchanger 22 and thus a temperature of a pipe of the heat exchanger 22 is inhibited from being excessively increased by heat of the heat transfer medium W.SELECTED DRAWING: Figure 3 【課題】緊急停止時に伝熱媒体に埋められた熱交換器を適切に保護することができるボイラシステムを提供する。【解決手段】ボイラシステム１００は、伝熱媒体との間で熱交換を行う流体が流れる熱交換器２２を備える。この熱交換器２２は、火炉３で加熱された伝熱媒体Ｗ中に埋められている。また、ボイラシステム１００は、少なくとも熱交換器２２内の流体の流れが減少又は停止する緊急停止時において、熱交換器２２の周囲から伝熱媒体を除去する除去部２４を備えている。従って、緊急停止時に熱交換器２２内の流体の流れが減少又は停止しても、熱交換器２２の周囲から伝熱媒体Ｗが除去されるため、伝熱媒体Ｗの熱によって熱交換器２２の管の温度が高くなりすぎることを抑制できる。【選択図】図３
