Reforming system and engine system
A reforming system includes a vaporizer configured to vaporize liquid fuel to produce fuel gas; a reformer configured to reform the fuel gas produced by the vaporizer to produce a reformed gas containing hydrogen; an air supplier configured to supply air to the reformer; a fuel gas supplier configured to supply the fuel gas to the reformer; a heater configured to increase a temperature of the reformer; a reformed gas flow passage through which the reformed gas produced by the reformer flows; a cooler disposed in the reformed gas flow passage and configured to cool the reformed gas; a circulation passage connecting the vaporizer with the cooler and through which refrigerant flows through the vaporizer and the cooler; and a circulation pump disposed in the circulation passage and configured to circulate the refrigerant through the circulation passage.
1. A reforming system comprising:
a vaporizer configured to vaporize liquid fuel to produce fuel gas;
a reformer configured to reform the fuel gas produced by the vaporizer to produce a reformed gas containing hydrogen;
an air supplier configured to supply air to the reformer;
a fuel gas supplier configured to supply the fuel gas to the reformer;
a heater configured to increase a temperature of the reformer;
a reformed gas flow passage through which the reformed gas produced by the reformer flows;
a cooler disposed in the reformed gas flow passage and configured to cool the reformed gas;
a circulation passage connecting the vaporizer with the cooler, and through which refrigerant flows through the vaporizer and the cooler; and
a circulation pump disposed in the circulation passage and configured to circulate the refrigerant through the circulation passage.
2. The reforming system according to claim 1 , wherein the reforming system further comprises a temperature adjuster disposed in the circulation passage and configured to adjust a temperature of the refrigerant that flows through the circulation passage.
3. The reforming system according to claim 2 , wherein the temperature adjuster cools the refrigerant that flows through the circulation passage to adjust the temperature of the refrigerant.
4. The reforming system according to claim 2 , wherein the temperature adjuster heats the refrigerant that flows through the circulation passage to adjust the temperature of the refrigerant.
5. An engine system comprising:
an engine;
an intake gas passage through which air flows to the engine;
a vaporizer configured to vaporize liquid fuel to produce fuel gas;
a reformer configured to reform the fuel gas produced by the vaporizer to produce a reformed gas containing hydrogen;
an air supplier configured to supply air to the reformer;
a fuel gas supplier configured to supply the fuel gas to the engine and the reformer;
a heater configured to increase a temperature of the reformer;
a reformed gas flow passage through which the reformed gas produced by the reformer flows toward the engine;
a cooler disposed in the reformed gas flow passage and configured to cool the reformed gas;
a circulation passage connecting the vaporizer with the cooler, and through which refrigerant flows through the vaporizer and the cooler; and
a circulation pump disposed in the circulation passage and configured to circulate the refrigerant through the circulation passage.
