METHOD TO RECOVER GAS-COMPRESSOR PLANT TURBINE DRIVE HEAT AND DEVICE TO THIS END Russian patent published in 2009 - IPC F02C6/18 

FIELD: engines and pumps.

SUBSTANCE: proposed method consists in directing turbine drive exhaust gases into exhaust heat boiler to generate steam to be forced to steam turbine and generating electric power by electric generator driven by said turbine. Before exhaust gases get into exhaust heat boiler, exhaust gases from all turbine drives incorporated with gas compressor plant are collected into common manifold for gases temperature, pressure and toxic substance concentration to be averaged. Steam is generated in exhaust heat boiler with after-burning of additional fuel therein to ensure steam optimum temperature and reduce concentration of toxic substances. Produced electric power is fed into frequency-controlled drive of electrically driven gas-compressor plant that maintains optimum gas parametres at plant outlet. Surplus portion of electric power is intended for plant service consumption and feeding outer loads, while residual heat of exhaust gases from aforesaid boiler and that of steam turbine waste gases are also recovered. Electrically driven gas-compressor plant with frequency-controlled drive is installed at ultimate position, given in-series interconnection of has-compressor plants, while aforesaid frequency-controlled drive is connected to steam turbine electric generator.

EFFECT: higher efficiency.
