STEAM PLANT Russian patent published in 1998 - IPC

FIELD: power-plant engineering; thermal-to- mechanical energy conversion. SUBSTANCE: plant has steam generator 1, turbine runner 2, and condenser 3. Steam generator 1 is provided with heater connected to heat source. Pipeline 4 connects steam generator 1 to nozzle guide vanes 5. Condenser 3 has hollow heat-transfer wall 6 and communicates through pipeline 7 with steam generator 1. Auxiliary steam plant has nozzle guide vanes 8, turbine runner 9, condenser 10 with heat-transfer condensing wall 11. Mechanical design of auxiliary plant is similar to that of main one; functioning as auxiliary-plan steam generator is hollow condensing wall 6. Condenser 10 communicates with interior of condensing wall 6 through pipeline 12. Plant is mounted in bearing supports 13 on common shaft 14. Turbine runners 2 and 9 are mounted in bearing supports 15 and 16 and rotate in opposite directions relative to plant body. Additional superheater for additional working medium and unbalanced masses mounted on runner rims of main and auxiliary plants opposing their rotation and raising torques of forces setting plant body plant body in rotary motion may be used. EFFECT: improved efficiency of steam plant. 3 cl, 1 dwg
