FIELD: turbo-machines.
SUBSTANCE: turbine machine design with heat exchanger, integrated into of turbine machine hot gases flow (1) outlet gas-air duct (10), characterized by that heat exchange elements (60, 60a-60i; 9), installed in one of components (11, 14, 14a, 14b, 15, 16, 16a, 16b, 18, 18a, 18c) of outlet gas-air duct (10), are made with possibility of directing hot gases (1) flow part, passing through heat exchange components, with further use of residual heat energy of said part of hot gases flow (1) to increase power on turbo-machine (20, 20a, 20b) shaft (30, 31), leaving larger part of hot gases flow (1) undisturbed.
EFFECT: enables to achieve optimum total compromise between technical characteristics, weight and operating costs.
