GAS-TURBINE POWER-GENERATING PLANT Russian patent published in 2007 - IPC F04D25/02 

FIELD: power engineering.

SUBSTANCE: proposed gas-turbine power-generating plant contains container, gas-turbine engine, free power turbine hydrodynamically coupled with engine, behind-the-turbine diffuser, engine starting system, air intake and exhaust devices and self-contained oil-pressure station and useful load set. Container consists of load-bearing frame, skeleton with floor, roof and side walls with heat insulating sheathing forming space for arrangement of gas-turbine engine on frame. Air intake and exhaust devices installed on container from outside are connected, respectively, with engine and free turbine. Useful load set is connected to free turbine by transmission. Plant contains also air intake chamber with air cleaner at inlet, additional extraction useful-load set, power plant control system, device for forced ventilation of container inner space and system for blowing through gas-air duct of engine and power turbine. Main useful load set, self-contained oil-pressure station and plant control system are installed in separate containers of design similar to that of main container. Additional container for arrangement of main useful load set is arranged from side of free turbine exhaust device. Useful load additional extraction set is gas-dynamically coupled with exhaust device of free turbine. Air intake chamber is butt-joined to end face wall of main container from side of engine air intake device whose inlet is arranged in chamber over its floor. Exhaust device of free turbine is arranged on opposite end face wall of main container in space between main container and container for arrangement of main useful load set.

EFFECT: increased efficiency, service life of plant, ecological safety, possibility of use different types of gas-turbine engines in plant.
