PROBLEM TO BE SOLVED: To provide a gas turbine device which can be continuously operated through combustion reaction of low calorie gas generated in a refuse gasified furnace or the like with a relative high degree of efficiency, and to provide a method of burning fuel gas in a gas turbine device. SOLUTION: A combustor 3 constituting a gas turbine device 1 is composed of a first and a second combustion zone 13, 14 which are alternately operated for combustion, a passage change-over device 2 which can introduce low calorie gas having a relative low temperature into the first and second combustion zone 13, 14, alternately, a first and a second heat-exchanger 11, 12 interposed between the flow change-over device 2 and the first and second combustion zone 11, 12, a selector valve device 30 which can introduce compressed gas from a compressor 4 into the first and second combustion zone 11, 12, alternately, and a dividing flow zone 15 for dividing combustion gas H generated in the first and second combustion zone, into a first and a second branch stream H1, H2. The low calorie gas is heated when it flows through the first and second heat-exchanger, and is then introduced into the first and second combustion zone 13, 14.
