Abstract: A control system for decreasing pressure of a supercritical water system and a method therefor is provided, mainly including: a resistance water storage tank, a resistance pump, a capillary negative booster, a back pressure valve, a regulating valve and related stop valves. By switching the back pressure valve branch and the capillary negative booster branch, the pressure regulation is achieved while starting the system, closing down and in normal operation. The present invention is capable of achieving precisely controlling pressure of the system on the basis of effectively preventing problems exists in the solid particle materials pressure decreasing process such as abrasion and clogging of the internal elements of the valve. In addition, the back pressure valve branch is capable of reducing the operation complexity in the starting and shutdown process of the system, and the operation reliability is improved.
