METHOD OF PRODUCTION OF HEAT ENERGY IN STEAM POWER-GENERATING PLANT Russian patent published in 2004 - IPC

FIELD: heat power engineering. SUBSTANCE: invention can be used in designing new steam power-generating plants and modification of existing plants. According to proposed method, working steam is passed through steam turbine from which at least one intermediate extraction is effected with condensing of waste steam with yield of heat, compression of waste steam at compression of waste steam from turbine exhaust being carried out at operating conditions corresponding to 2-15% of passage of steam through low-pressure part of turbine, and condensing of said steam with yield of heat is effected after compression. EFFECT: increase thermal efficiency of steam power generating plane, improved ecological characteristics. 1 dwg
