PROBLEM TO BE SOLVED: To provide a control device of process steam utilizing a steam turbine with long life while stabilizing a feeding steam pressure. SOLUTION: A steam generation source 1 and a high pressure header 5 are connected by a steam feeding pipe 2. The high pressure header 5 and a plurality of steam turbines 3, 4 arranged in parallel are connected by branch pipes 10, 11. Control valves 6, 7 and pressure sensors 8, 9 are mounted to the branch pipes 10, 11. Outlets of the steam turbines 3, 4 are connected to a low pressure header 12 and the steam feeding pipe 2 is communicated with it. Since the steam pressure fed from the high pressure header 5 to the steam turbines 3, 4, is controlled by the control valves 6, 7 so as to form high/low difference, the steam pressure fed to a steam use position is stabilized.
