BOILER SYSTEM

摘要

A boiler system includes: a boiler unit which heats boiler water by using the waste heat of a motor as a heat source; a second pump which circulates boiler water through a second circulation path; and a heat storage unit which exchanges heat between a heat storage material and boiler water flowing in the second circulation path. The heat storage unit stores heat by heating the heat storage material by boiler water when the temperature of the heat storage material is lower than the temperature of the boiler water and heats boiler water by the heat storage material when the temperature of the heat storage material is higher than the temperature of the boiler water. The boiler system in a simple structure heats boiler water by using stored waste heat while storing the waste heat of a motor by adding the heat storage unit, the second pump, and the second circulation path to the boiler unit which supplies steam to a steam system in a vessel.
