PROBLEM TO BE SOLVED: To provide a technology capable of appropriately adjusting distribution supply and distribution ratio of fuel F such as liquid fuel to be distributed to a flow passage 2 for main combustion and a flow passage 3 for pilot combustion on the basis of a combustion load so that stable combustion condition can be maintained, while reducing NOx, in regard to a combustion device 100 to be used for a gas turbine engine. SOLUTION: The combustion device is provided with a fuel injection nozzle 5 for injecting fuel F in the distributed condition, and the fuel injection nozzle 5 is structured possible to adjust distribution angleθwith adjustment of injection quantity of the fuel F in the condition wherein high-combustion-load distribution angleθH when a high combustion load is applied and low-combustion-load distribution angleθL when a low combustion load is applied are different from each other. The flow passage 2 for main combustion receives the fuel F injected at the high-combustion-load distribution angleθH, and the flow passage 3 for pilot combustion receives the fuel F injected at the low-combustion-load distribution angleθL.
