FIELD: heat power engineering.
SUBSTANCE: proposed steam-gas plant recovers heat of exhaust gases in recovery boiler with generation of steam in steam-water duct owing to the fact that exhaust gases are directed tangentially relative to inner surface of cylindrical shell of recovery boiler, and owing to rarefaction in middle part of vortex flow of exhaust gases, air is sucked from atmosphere which, together with water vapors and other components of exhaust gases, are fed to suction system of compressor of gas-turbine plant, and steam is generated on outer surface of cylindrical shell of recovery boiler which is delivered into combustion chamber of gas-turbine plant. Device contains cylindrical shell in center of which atmospheric air suction pipe is installed coaxially to inner surface of housing. outlet of pipeline to intake exhaust gases is directed tangentially to inner surface of cylindrical shell and outlet of pipeline to feed water is arranged outside cylindrical shell in water-steam space in form of truncated cone.
EFFECT: increased economy and improved reliability of operation of steam gas plant, reduced metal usage of recovery boiler.
