The control system 26 is a PLC or DCS circuit control system.

[0019] The discharge valve 21 is a pneumatic on-off valve, model Q611 F-16C, preferably a pneumatic plug valve, the discharge valve 22 is a pneumatic regulating valve, model HVFF-6mm, preferably a pneumatic plug valve, the control valve 23 is a pneumatic ball valve, model Q347F, the pressure reducing valve 25 is a steam pipe pressure reducing valve with automatic control, model DN20-300, and the pressure gauge 24 is a remote pressure gauge, model YTZ-150.

[0020] The storage medium in the steam storage tank 3 is steam, and the steam pressure is greater than the pressure when it is discharged from the high-pressure reactor 4.
