PROBLEM TO BE SOLVED: To provide the improved combination of a premixing chamber 112 and a combustion chamber 111 with low emission of pollutants for a gas turbine running on liquid fuel and/or fuel gas. SOLUTION: In this combination, the combustion chamber 111 comprises an end part 111a of truncated conical shape, and is surrounded by a hollow 115 for cooling air 120. The hollow 115 carries combustion air 120a into the premixing chamber 112, and the premixing chamber 112 comprises, at an inlet, an opening or a port 126 capable of being restricted according to the amount of used fuel, and comprises, at an outlet, the peripheral assembly of a burner 134 installed to produce the corresponding set of an additional flame. A fuel gas supply means 125 and a liquid fuel injection device 119 are installed in the premixing chamber 112, and the set of a liquid fuel injector 140 is positioned on the end part 111a thereof.
