MULTI-PURPOSE GAS TURBINE POWER PLANT Russian patent published in 2009 - IPC F02C6/08 F01K21/04 

FIELD: engines and pumps.

SUBSTANCE: multi-purpose gas turbine power plant is made in the form of two functional modules: compressed air generator module made in the form of an auxiliary gas turbine engine, and steam turbine generator module, with auxiliary module systems connected by means of controlled compressed air distribution station. The latter is made so that discrete or smooth distribution of compressed air can be performed between external consumer or external network and steam turbine generator module. Steam turbine generator module is made in the form of steam-air turbine and generator with kinematic connection between them, and consists of heat-recovery boiler and mixing chamber. Superheated steam is generated in heat-recovery boiler, and superheated steam from heat-recovery boiler is mixed with compressed air in the mixing chamber. Steam-air mixture from the mixing chamber is supplied to steam-air turbine. The installation can also include contact water vapour condenser, cooler and water service tank, controlled steam-air mixture extraction station located between the mixing chamber and steam-air turbine. Functional modules of compressed air generator and turbine generator with auxiliary module systems can be installed on individual underframes.

EFFECT: multifunctional performance and flexibility of choosing operating modes, increasing life time of steam turbine generator module and improving environmental characteristic of multi-purpose gas turbine power plant.
