GAS-TURBINE PLANT Russian patent published in 2007 - IPC F02C3/14 

FIELD: heat power engineering.

SUBSTANCE: invention can be used in different industries and on compressor stations of gas lines. Proposed gas-turbine plant contains turbine, compressor, regenerator and at least one extension combustion chamber. Combustion chamber has channels to deliver hot air to turbine blades. Output of regenerator is connected with input of combustion chamber. Rear lip of holder at turbine output is connected to outer housing of gas-turbine plant at one side, and compressor housing is connected at other side, thus forming common ring space. Mounted inside ring space are output part of combustion chamber housing terminating in transient branch pipe with inner contraction channel secured in front part of holder at turbine input and smoothly changing into ring channel to deliver hot has into turbine and preventing ingress of air from compressor into turbine. Output of compressor is connected with input of regenerator through common ring space and holes in outer housing.

EFFECT: increased efficiency of gas-turbine plant, reduced thermal stresses on its members owing to provision of uniform and effective cooling and increased service life of plant.
