装置。 An auxiliary steam supply system that maintains the steam extracted from the reheat steam system at a predetermined pressure and temperature into a container serving as an auxiliary steam source, and supplies it from there to equipment in the plant. A pressure regulating valve and a desuperheater are installed to reduce the pressure and temperature of the extracted main steam and collect it in the container, and when the pressure and temperature of the auxiliary steam source are below the determined conditions, the steam pressure and temperature can be increased The auxiliary steam supply device is characterized in that main steam is sent into the container through the pressure regulating valve and the attemperator so as to maintain the temperature of the main steam.
