FIELD: gas turbines. SUBSTANCE: gas turbine has a number of pipelines arranged so that part of combustible gas is branched off and passed through pre-forming catalytic stage for converting hydrocarbon contained in it to alcohol and/or aldehyde; then it is brought to combustible gas to reduce its ignition temperature. In this way, rather easily inflammable materials (alcohol and/or aldehyde) can be produced in pre- formation stage. Combustible gas is mixed up with these materials which reduces its ignition point compared with that not passed through pre-forming stage. EFFECT: reduced ignition temperature of combustible gas. 5 cl, 1 dwg
