Title:
WASTE HEAT RECOVERY SYSTEM, SHIP, AND METHOD FOR OPERATING WASTE HEAT RECOVERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/071270
Kind Code:
A1
Abstract:
This waste heat recovery system includes: a combustion device capable of using two or more types of fuels by switching therebetween; an exhaust gas line through which exhaust gas from the combustion device flows; a vessel for storing saturated water and steam; a water supply line for supplying water to the vessel; a saturated steam line through which the saturated steam from the vessel flows; a heat exchanger that is provided in the exhaust gas line and is for heating the water in the water supply line by performing heat exchange between the water and the exhaust gas; a valve that is provided in the saturated steam line and is for adjusting the pressure in the vessel; and a control unit that is configured to adjust, upon receiving a signal indicating that the fuel supplied to the combustion device has been switched, the valve aperture on the basis of the signal to change the pressure in the vessel. The control unit is configured to adjust the valve aperture so that the pressure in the vessel is a second pressure when the fuel is a second fuel and a first pressure lower than the second pressure when the fuel is a first fuel having a lower sulfur concentration than the second fuel.
