PROBLEM TO BE SOLVED: To stably control injection of fuel gas by preventing the fuel gas from being overheated, in a fuel supply method using fuel gas and liquid fuel by switching them according to an operational condition. SOLUTION: Fuel gas is cooled by liquid fuel on the upstream side of a fuel gas injector 24. As a means for this cooling, a fuel gas transfer passage 15a forming a fuel gas supply passage and a liquid fuel transfer passage 10a forming a liquid fuel supply passage are disposed on the upstream side of the fuel gas injector 24 in the fuel gas supply passage so that heat of the fuel gas is transferred to the liquid fuel. |
