Abstract
The present invention is directed to a high pressure fluidized bed system using dual control valves, and an inner pressure control method thereof. The high pressure fluidized bed system includes a fluidized bed reactor, a pressure sensor which measures a pressure in the interior of the fluidized bed reactor, a cyclone part which is coupled to the fluidized bed reactor, a first valve allowing controlling of the exhaust gas, and a second valve allowing manually controlling of exhaust gas except for the exhaust gas controlled by the first valve. The first valve is capable of opening and closing automatically, and the second valve is capable of opening and closing manually, and are used in combination in the high pressure fluidized bed, allowing decreasing of the pressure variation within the reactor and improving the operation stability of the reactor.
