TWO-ROTOR AIR COMPRESSOR FOR COMBINED-CYCLE PLANTS Russian patent published in 2014 - IPC F01K3/00 

FIELD: machine building.

SUBSTANCE: two-rotor air compressor for combined-cycle plants is proposed, its common housing hosts a low-pressure rotor coupled with a recovery steam turbine set on the side of the atmospherical air suction into the compressor and a high-pressure rotor coupled with a gas turbine set on the compressor discharge side. The air compression rate in the low-pressure compressor ε₁ is defined on the condition that the recovery steam turbine output is equal to the low-pressure compressor output, and the air compression rate in the high-pressure compressor ε₂ is equal to $${\epsilon }_2=\raisebox{1ex}{$\epsilon $}\!\left/ \!\raisebox{-1ex}{${\epsilon }_1$}\right.,$$ where ε stands for the total rate of air compression in the two-rotor compressor.

EFFECT: invention is aimed at increasing the maximal output of combined-cycle plants.
