Zusammenfassung:To provide a boiler system that prevents generation of carbon dioxide by using a metal material as fuel, and performs heat recovery equivalent to that in the case of using coal as fuel.SOLUTION: A boiler system comprises: a boiler 100 comprising a furnace 10, and combustion burners 21-25 for injecting a metal material and combustion air into the furnace 10, and for generating combustion gas containing metal oxide by burning the metal material; and a recirculation fan 600 for supplying inert gas having a temperature lower than that of the combustion gas discharged from the boiler 100, to the combustion burners 21-25.SELECTED DRAWING: Figure 2 【課題】金属材料を燃料として用いることにより二酸化炭素の発生を防止するとともに、石炭を燃料として用いる場合と同等の熱回収を行うボイラシステムを提供する。【解決手段】火炉１０と、火炉１０へ金属材料および燃焼用空気を噴射する燃焼バーナ２１～２５を有し、金属材料を燃焼させて金属酸化物を含む燃焼ガスを生成するボイラ１００と、ボイラ１００から排出される燃焼ガスよりも低温の不活性ガスを燃焼バーナ２１～２５へ供給する再循環ファン６００と、を備えるボイラシステムを提供する。【選択図】図２
