An evaporator control system includes water supply amount control means for controlling at a target temperature the temperature of steam generated by heating water supplied to an evaporator with thermal energy of exhaust gas of an engine, by manipulating the amount of water supplied. The water supply amount controller determines the amount of water supplied to the evaporator based on the sum of a feedforward water supply amount calculated from an amount of change in a parameter representing a load state of the engine, a first feedback water supply amount calculated from the actual temperature of the steam generated by the evaporator, and further a second feedback water supply amount calculated from a parameter representing an internal state of the evaporator such as an internal density of the evaporator.
