REGENERATIVE GAS-TURBINE DRIVE OF GAS-TRANSFER SET Russian patent published in 2006 - IPC F04D25/02 

FIELD: gas industry; gas mains compressor stations.

SUBSTANCE: proposed gas-turbine drive of gas-transfer set has gas-turbine plant coupled with unit consisting of two gas-air regenerators. Device for mixing cycle air made in form of horizontally arranged cylindrical reservoir is placed between regenerator unit and combustion chamber of gas-turbine set. Partition with central is installed inside reservoir. Two inlet and two outlet branch pipes are provided in reservoir symmetrically to central hole, branch pipes being connected, respectively, with outlet ducts of cycle air of regenerators and inlet ducts of cycle air of combustion chamber. Partition with central hole can be displaced relative to longitudinal axis of reservoir to side of inlet branch pipe through distance equal to 0.05-0.1 of inner diameter of reservoir. Ducts of cycle air between regenerators and reservoir can be provided with expansion bands.

EFFECT: reduced nonuniformity of temperature field in combustion chamber and before high-pressure turbine, reduced degree of defects of units of combustion chamber, turbine and hot ducts of gas-turbine plant.
