The invention relates to heat power engineering and can be used in systems and installations for improvement of vapor condensation. A steam-power unit had steam turbine 1 with electric generator 2, condenser 3 of worked-out vapor with condensate water pump 4 and steam-jet ejector 8. The unit has a heat-insulated evaporation tank 6. Its upper vapor cavity is connected to the steam-jet ejector 8 through capillary steam pipes 7 connected by collector. Its lower liquid cavity is connected through supercharge water pump 9 to sprinkling nozzles 5 and through electromagnetic valve 11 and indicator 12 of liquid level installed in the evaporation tank – to the condensate water pump 4. The capillary vapor pipes 7 are made of hydrophilic material dimensions of pores of which are within 20-150 μm. The invention promotes improvement of vapor condensation and decrease of back pressure in turbine, this increases its power. |
