PURPOSE:To make it possible to form an uniform gas flow using a single fuel injection valve by supplying a pre-evaporation, pre-mixing gas generated by a pair of fuel injection valve and evaporation tube to a scroll chamber. CONSTITUTION:An annular combustion chamber 6 which is concentric with a rotor shaft 3 is provided around a bearing box 4 for the rotor shaft 3 of a gas turbine. A distribution chamber 8 of scroll type or plenum type which distributes an uniform flow of a pre-mixing gas is provided along the top section of the annular combustion chamber 6. Further, a pair of evaporation pipe 9 and fuel injection valve 10 which generate a pre-mixing gas are connected to the distribution chamber 8. As a result, it is made possible to form an uniform gas flow by a single fuel injection valve. Furthermore, it is made possible to maintain a low NOx with a simple and compact constitution, and this burner becomes suitable for a prime mover for vehicles.
