"textContent": "Disclosed are a control method and a control device for an exhaust heat recovery system which are capable of preventing an onboard supply power outage in response to a sharp change in the load of the main drive machine- For an exhaust heat recovery system for which a portion of the exhaust gas generated by the ship's main drive machine is supplied to a gas turbine and the amount of heat of the exhaust gas exhausted by the gas turbine is conducted to an exhaust gas economizer, this control method and control device: obtain an estimated or calculated current reserve amount of heat (Q), which is based on the heat energy detection signal of the exhaust gas economizer; obtain, based on the operation state of an auxiliary electrical generator and on the onboard power demand, a reference amount of heat (Q min ), which is required to maintain the requisite power until the auxiliary electrical generator starts up; compare the current reserve amount of heat (Q) and the reference amount of heat (Q min ); and, based on the result of the comparison, select the operating state of the auxiliary electrical generator from either stop, idle or driving operation.",
