In the present invention, the system is equipped with a flow rate adjustment valve 160 provided in a flow path 150 on the downstream side of a first heat exchanger 130, said flow rate adjustment valve 160 controlling the flow rate of steam. The flow rate of the steam is controlled by the flow rate adjustment valve 160 so as to maintain the preheating temperature of a slurry and to keep the pressure of the steam for preheating the slurry higher than the pressure of the slurry. By preheating a slurry that contains wet biomass using high-pressure steam of at least the pressure of the supercritical water gasification system via the first heat exchanger 130, the heat exchanger 130 can be made more compact while minimizing fuel consumption, the generation of tar and char can be suppressed, clogging of the pipes of the heat exchanger 130 can be avoided, and fuel gases such as methane and hydrogen can be generated more efficiently from the wet biomass.
In the present invention, a first heat exchanger 130 preheats a slurry body including a water-containing biomass by using steam from a drum type boiler 140, thereby making it possible to minimize the fuel cost, reduce the size of the first heat exchanger 130, suppress the generation of tar and char, prevent the piping of the first heat exchanger 130 from blocking, and more efficiently generate a fuel gas. Further, when preheating is performed, a flow rate adjusting valve 160 adjusts the flow rate of the steam to control the temperature of the slurry body at the outlet of the first heat exchanger 130, thereby making it possible to avoid insufficient increase in temperature of the slurry body at the outlet of the first heat exchanger 130. Therefore, the present invention can eliminate the heater provided between the first heat exchanger 130 and a gasification reactor 141 in the conventional system.
