  • Heat exchanger, energy recovery system, and vessel
    Patent number: 10408092
    Abstract: A heat exchanger is for use in an energy recovery system to be mounted on a vessel including an engine, a supercharger and an economizer, the heat exchanger including: a first heat section for heating a working medium by supercharged air from the supercharger; a second heat section for heating the supercharged air by steam generated by the economizer before the supercharged air flows into the first heat section; and a third heat section for heating the working medium having been heated in the first section by the supercharged air which is to be heated in the second section.
    Type: Grant
    Filed: February 2, 2016
    Date of Patent: September 10, 2019
    Assignees: Kobe Steel, Ltd., ASAHI SHIPPING CO., LTD., TSUNEISHI SHIPBUILDING CO., LTD., MIURA CO., LTD.

  • Heat energy recovery system
    Patent number: 10047638
    Abstract: Disclosed is a heat energy recovery system including: a heat energy recovery circuit that causes a working medium to circulate by means of a circulation pump to exchange heat with supercharged air from a supercharger via a first heater and exchange heat with steam from an exhaust-gas economizer via a second heater, in order to integrally drive a turbine and a generator; and a controller that performs stop control to stop the circulation pump based on the flow state of the steam in a first steam flow path that causes the steam to flow from the exhaust-gas economizer to a soot blower.
