PROBLEM TO BE SOLVED: To provide a system that has a simple structure for storing waste heat of a prime mover and using the stored waste heat.SOLUTION: A boiler system 1 is provided with: a boiler part 50 for heating boiler water by using waste heat of a prime mover 3 as a heat source; a second pump 55 for circulating the boiler water via a second circulation passage 522; and a heat storage part 59 for exchanging heat between a heat storage material and the boiler water flowing through the second circulation passage 522. In the heat storage part 59, the heat storage material is heated by the boiler water to store heat when the temperature of the heat storage material is lower than the temperature of the boiler water, and the boiler water is heated by the heat storage material when the temperature of the heat storage material is higher than the temperature of the boiler water. In this way, by adding the heat storage part 59, the second pump 55, and the second circulation passage 522 to the boiler part 50 for supplying steam to a steam system in a ship, the boiler system 1 that has a simple structure for storing the waste heat of the prime mover 3 and heating the boiler water by using the stored waste heat can be provided. 【課題】原動機の廃熱を蓄えるとともに蓄えられた廃熱を利用する簡素な構造のシステムを提供する。【解決手段】ボイラシステム１では、原動機３の廃熱を熱源としてボイラ水を加熱するボイラ部５０と、第２循環路５２２を介してボイラ水を循環させる第２ポンプ５５と、蓄熱材と第２循環路５２２を流れるボイラ水との間で熱交換を行う蓄熱部５９が設けられる。蓄熱部５９では、蓄熱材がボイラ水よりも低温の場合、ボイラ水により蓄熱材が加熱されて蓄熱が行われ、蓄熱材がボイラ水よりも高温の場合、蓄熱材によりボイラ水が加熱される。このように、船内の蒸気システムへと蒸気を供給するボイラ部５０に、蓄熱部５９、第２ポンプ５５および第２循環路５２２を追加することにより、原動機３の廃熱を蓄えるとともに蓄えられた廃熱を利用してボイラ水を加熱する簡素な構造のボイラシステム１を提供することができる。【選択図】図１
