|1. (WO2018101043) THERMAL ENERGY RECOVERY DEVICE AND STARTUP OPERATION METHOD FOR SAME|
|Applicants:||KABUSHIKI KAISHA KOBE SEIKO SHO (KOBE STEEL, LTD.)
|Title:||THERMAL ENERGY RECOVERY DEVICE AND STARTUP OPERATION METHOD FOR SAME|
Provided is a thermal energy recovery device comprising the following: a circulation path in which a working medium is circulated; a thermal fluid circulation path through which flows hot water; an evaporator that evaporates the working medium flowing in the circulation path by heat from the hot water flowing through the thermal fluid circulation path; a preheater that heats the working medium, prior to the medium flowing into the evaporator, using heat from the hot water flowing through the thermal fluid circulation path; and a control unit that performs control for startup operation of the thermal energy recovery device. The control unit performs suppression control to suppress the difference in temperature between the hot water in the preheater and the working medium during the startup operation.
