PURPOSE:To enhance the application efficiency of process steam by controlling a pressure regulation valve as to maintain the process steam at a specified pressure via a pressure regulation setting means when the process steam is lean and as to make the steam at a turbine set pressure when the process signal is excess. CONSTITUTION:When a pressure gauge 12 detects any lean of pressure of process steam, a controller 25 opens a cut-off valve 21 and a steam pressure control valve 8 is controlled as to make a pressure regulation setting means maintain the pressure of the process steam at a specified value. On the other hand, when the process steam is excess, the controller 25 controls the steam pressure control valve 8 on the basis of the output signal of the pressure gauge 12 so that the steam pressure may become the set pressure of mixed pressure steam, with a generator's output gauge 24 monitoring the output of a generator 4. |
