PROBLEM TO BE SOLVED: To provide an auxiliary steam supply device capable of efficiently supply one series of auxiliary steam to an outdoor facility by attaching a pressure/temperature detection part to the outlet of each temperature reducer to automatically operating the temperature reducer of each series and controlling a temperature-reduced water pump according to the detected results of the pressure or temperature of the auxiliary steam. SOLUTION: The No. 1 series of this auxiliary steam supply device 100 comprises a communication valve 3 for converging a steam supplied from a main steam pipe 23 to a steam supplied from a main steam pipe 24, a pressure regulating valve 2 for reducing the pressure of the steam supplied from the main steam pipe 23, a supply valve 4 for passing or stopping the depressurized steam, the temperature reducer 5 for lowering the temperature of the depressurized steam, the temperature-reduced water pump 7 for supplying a cooling water 26 to the temperature reducer 5, the pressure/temperature detection parts 8 for detecting the pressures and temperatures at the outlets of the temperature reducers 5, and a control part 22 for controlling the communication valve 3, the supply valve 4, and the temperature-reduced water pump 7.
