  • water supplied to the exhaust gas heat recovery boiler 81 and water / steam piping 82 through which steam obtained there flows are indicated by a one-dot chain line.
  • FIG. 12 like FIG. 4 (3rd Embodiment), illustration of the system
  • the solid fuel can be liquefied using the exhaust gas of the diesel engine 11 as a heat source.
  • it can utilize as a heat source of higher temperature than the 6th and 7th embodiment which uses the cooling water of the diesel engine 11 as a heat source.
  • the diesel engine 11 is taken as an example of the heat engine.
  • the present invention is not limited to the diesel engine, but can be applied to a heat engine using a gas turbine or a steam turbine.
  • the heat source of the first embodiment is replaced with the exhaust gas of the diesel engine 11.
  • the heat source of the second embodiment can be replaced with the exhaust gas of the diesel engine 11.
  • the heat source of the sixth embodiment is replaced with the exhaust gas of the diesel engine 11, but the heat source of the seventh embodiment can be replaced with the exhaust gas of the diesel engine 11.
  • both the heat obtained from the cooling water of the diesel engine 11 and the heat obtained from the exhaust gas of the diesel engine 11 are supplied to the fuel circulation pipe.
  • the system may be used as a heating source for the fuel circulating through 20.
  • the features of the sixth or seventh embodiment and the features of the eighth embodiment can be combined.
  • the fuel heaters 14 and 83 are exemplified as those that use the exhaust heat of the heat engine, but are not limited to those that use the exhaust heat of the heat engine.
  • a boiler or an electric heater provided with a combustor may be used as another heat source.
  • the transport tank mounting portion 21 has the stirrer 48.
  • the transport tank mounting portion 21 does not have the stirrer 48, and the fuel discharge pipe 241 and the fuel suction pipe 242 are used. It is also possible to simply circulate the fuel through and stir.
  • one transport tank mounting portion 21 is attached to one transport tank 12, but two or more transport tank mounting portions 21 are attached to one transport tank 12. May be attached. Thereby, the fuel in the transport tank 12 can be liquefied in a shorter time.
