METHOD OF OPERATION OF GAS-STEAM PLANT Russian patent published in 2006 - IPC F01K21/04 

FIELD: power engineering; ship engines.

SUBSTANCE: according to proposed method atmospheric air is compressed, contactly cooled and regeneratively heated by heat of waste steam-gas mixture, and fuel is combusted in said air with supply of power-generating steam flow into fuel combustion zone. Steam-gas mixture, thus formed, is expanded and useful work of expansion is used for compressing air and executing external work, generating electric energy for driving different mechanisms, for instance, vehicles. heat of steam-gas mixture, after expansion and regenerative removal of heat, is recovered for generation of steam, steam-gas mixture is cooled, its steam component is condensed and condensate, thus formed, is cooled and used for cooling and condensing of steam-gas mixture. Cooling of compressed moistened air is carried out at its contact with water in saturated state, or with saturated water vapor formed at recovery of heat of waste steam-gas mixture, and overheated steam is used as power-generating steam flow and for cooling of steam-gas turbine.

EFFECT: increased thermal economy of gas-steam plant.
