Moreover, at this time, neck 1. Due to constraints from the pond side, it is necessary to increase the pressure and flow rate in order to suppress the difference between the fuel pressure and air pressure within the cell to 3 to 5XIQ-''atmospheres or less. In the configuration, the slurry adjustment valves 1 to 3 must be adjusted so that the above differential pressure conditions are satisfied in both the flow rate increase process and the pressure increase process, and therefore, the adjustment of valves 1 to 3 is necessary. However, as a result, valves 1 to 3 had to be opened gradually, resulting in a long start-up time.
