Problems solved by technology
[0006] However, according to the marine energy storage system of Document 2, in order to use the stored thermal energy as a power source for power generation, a large heat storage facility is required
In addition, since the conversion efficiency is low when converting thermal energy into power, it is difficult to efficiently utilize the accumulated thermal energy
On the other hand, in the marine thermal storage system of Document 3, the system for recovering the waste heat of the main engine, the system for storing heat in and releasing heat from the thermal storage tank, and the thermal energy of the thermal storage tank by using the heat medium on the utilization side The systems that supply the utilization equipment need to be independent, so the structure of the thermal storage system for ships becomes complicated

Embodiment Construction
[0051] figure 1 It is a figure which shows the structure of the boiler system 1 which concerns on 1st Embodiment of this invention. The boiler system 1 is used, for example, as an auxiliary boiler system for larger ships. figure 1 In addition, the prime mover 2 with a supercharger used as the main engine of a ship is shown together. The boiler system 1 uses waste heat from a prime mover 2 with a supercharger to heat boiler water as a medium. The steam generated from the heated boiler water is used as a heating source for fuel oil, lubricating oil, domestic water, etc. in the ship.
[0052] The prime mover 2 with a supercharger includes: a marine prime mover 3 (hereinafter simply referred to as "prime mover 3") as an internal combustion engine; and a supercharger 4 as a turbocharger. The prime mover 3 is the main engine of the ship, such as a two-stroke diesel engine. The supercharger 4 includes a turbine 41 and a compressor 42 mechanically connected to the turbine 41 . Th...

The present invention provides a furnace system. The furnace system comprises a furnace part which utilizes wasted heat from an original machine to head water in the furnace. A second pump enables water in the furnace to circulate through a second circulation channel. A heat storing part is used for realizing the heat exchange between a heat storing material and its flowing second circulation channel. In the heat storing part, when the temperature of the heat storing material is lower than that of water in the furnace, the heat storing material stores heat by using the water in the furnace; when the temperature of the heat storing material is higher than that of the water in the furnace, the heat storing material is used to heat the water in the furnace. In this manner, by adding a heat storing part, a second pump and a second circulation channel at the top part of the furnace where steam is provided to a steam system inside a boat, the original machine provided in the furnace system can utilize stored waste heat to heat a furnace. The furnace system has a rather simple structure.
Description
technical field [0001] The present invention relates to boiler systems. Background technique [0002] Conventionally, large ships have installed exhaust economizers in the funnels that use waste heat from exhaust gases from the main engines to heat boiler water and generate steam. For example, in the exhaust economizer system shown in Japanese Patent Laid-Open Publication No. 2011-196646 (Document 1), the boiler water stored in the auxiliary boiler is sent to the exhaust economizer by the boiler water circulation pump, and passes through the exhaust economizer. Return to the auxiliary boiler after heating. [0003] Japanese Patent Laid-Open Publication No. 2010-116847 (Document 2) discloses an energy storage system that stores energy in a ship. In the energy storage system, a waste heat recovery device that recovers waste heat from the exhaust gas of the main engine using heat medium oil is provided, and the heat heated in the waste heat recovery device is supplied to the ...
