The invention relates to a method for producing hydrocarbon-containing gaseous fuel comprises at least three stages.In the first stage water is entered for heating and water steam forming in the second stage hydrocarbon component is entered and mixed with water steam by injecting The mixture is heated and directed to third and subsequent stages to additional heating for fuel producing.Turbo generator setup is made as two cylinder tubes, forming technological cylinder, divided on isolated sections. The first section is made with induction heat source for system start-up, the second section is made with injector type mixer. The inner tube cavity forms the firing chamber. In technological cylinder multistage components and mixture heated and additional heating in subsequent sections are realized until forming of hydrogen-containing gaseous fuel. Burning system is installed on the firing chamber inlet. Working torch forming element, as a restriction device is installed on the firing chamber outlet.
