METHOD OF OPERATION OF GAS-AND-STEAM TURBINE PLANT AND PLANT OPERATING ACCORDING TO THIS METHOD

摘要

mechanical engineering; turbine plants. SUBSTANCE: heat contained in expanded working medium corresponding to gas or liquid fuel operating gas turbine is used to produce steam for steam turbine placed in steam-and-water circuit. Condensed steam from steam turbine is supplied as condensate to steam- and-water circuit. Part of flow is branched off for heating both condensate and fuel in heat exchanger. EFFECT: increased efficiency of plant. 11 cl, 1 dwg
