GAS TURBINE PLANT Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed gas turbine plant has high-and low-pressure compressors, and main chamber coupled with high-pressure turbine and with low-pressure turbine. Intermediate heating combustion chamber is installed between high-pressure and low-pressure turbines. Two intermediate heating ring combustion chambers are arranged in peripheral parts of housing of high-pressure and low-pressure turbines. Inlets of cooling ducts of high-pressure turbine and low-pressure turbine are coupled with fuel-feed manifolds introduced additionally into turbine blade spaces. Outlets of corresponding ducts of turbines are connected with corresponding intermediate heating combustion chambers. EFFECT: increased efficiency of gas turbine plant. 1 dwg
