Cycles of gas turbine devices using liquid and gas fuels with chemical heat regeneration are considered. A thermodynamic analysis of one of these schemes was carried out using energy and enthalpy balances. The behaviour of the cycle was investigated as a function of the pressure in the chemical regenerator ( P ch ) and in the turbine ( P T ), and the temperature in the chemical catalytic regenerator ( T ch ). Calculations were carried out at P T ⩽ 10.0 MPa, P ch ⩽ 2.0 MPa and T ch ⩽ 600 K. As a result, it was shown that the thermal efficiency η T of the cycle with chemical regeneration of the exhaust gases increased by about 12%. The dependences of η T on P ch and T ch were obtained.
