The proposed article considers the theoretical prerequisites and proposes a scheme for a regenerative gas turbine installation with an increase in the degree of regeneration at constant recuperator sizes in order to increase the efficiency of the installation. The new scheme excludes the supply of secondary (cooling the heat pipe and combustion products in the combustion chamber) air to the heat exchanger for heating. Reducing the air flow in the recuperator to the values of only the primary (for fuel oxidation) air flow with the recuperator area unchanged leads to an increase in the degree of regeneration and, accordingly, the efficiency of the plant.
The possibility of significantly increasing the degree of regeneration in regenerative gas turbine plants without increasing the size of the recuperator.
