Abstract: FIELD: heat power engineering. 
     SUBSTANCE: invention can be used at creation and modernization of power-generating gas-turbine plants operating on natural gas as fuel.  According to known method of partial substitution of gas-turbine fuel in which air compressed by compressor of gas-turbine plant is heated before delivering into combustion chamber in recuperator by superheated steam generated in steam boiler at combustion of replacement fuel, steam into recuperator is fed directly after steam boiler, and after recuperator at least part of steam and reheated by exhaust gases of gas-turbine plant to temperature required by consumer, for instance, to required temperature of steam to be delivered to turbine.  According to invention, steam, before delivery into recuperator, can be superheated to temperature exceeding temperature required by consumer.  Moreover, part of reheated steam can be directed into combustion to be used in mixture with combustion products of gas-turbine fuel as working medium of gas-turbine plan. 
     EFFECT: possibility of use of low-cost ash-bearing fuels, such as coals, which can not be used in other spheres of application instead of natural gas.
