  • the PU 202 pressurized the lock hopper 34 as shown in FIG. 8 before opening the inlet valve 32. This reduces the load required to open the inlet valve 32. In particular, if the area of the inlet port 34a is large, and the difference between the pressure upstream and downstream of the inlet valve 32 is large, the load required to open the valve becomes significantly large. In response to this, by pressurizing the inside of the lock hopper 34 before opening the inlet valve 32, the load required to open the valve can be reduced.
  • the PU 202 pressurized the lock hopper 84 by increasing the methane concentration in the lock hopper 84 prior to opening the discharge valve 86.
