摘要： A working medium supply control system in a heat exchanger is provided. The heat exchanger (14) carries out heat exchange between an exhaust gas flowing through an exhaust passage of an internal combustion engine (11) and water flowing through a heat transfer tube (13), and the exhaust gas thereby heats the water to generate steam at a target temperature. The system is provided with a plurality of flow control valves (17a to 17j) that can individually regulate the amount of water supplied to a plurality of headers provided in the heat transfer tube (13), and control means (21) individually controls the amounts of water supplied via the respective flow control valves (17a to 17j) based on the rotational speed and the load of the internal combustion engine (11). This makes the temperature distribution of the heat transfer tube (13) coincide with a preset temperature distribution even when the operational state of the internal combustion engine (11) changes and the temperature and the flow rate of the exhaust gas change, thus converting input energy of the exhaust gas into output energy of the steam without consuming it in changing the temperature of the heat transfer tube (13), and thereby improving the transient responsiveness of the steam temperature. The temperature of the steam generated by the heat exchanger can therefore be controlled at a target temperature with good responsiveness even when the operational state of the internal combustion engine changes.
