FIELD: heat power engineering. SUBSTANCE: vacuum deaerator has vertical housing with branch pipes for supplying water of bubbling steam and for discharging deaerated water and steam-gas mixture. Inside the housing of the deaerator are jet compartment with a distributing plate and bubbling compartment including bubbling sheet, by-pass, and water discharging threshold. The deaerator is additionally provided with nozzle and intermediate compartments as well as additional vertical steam-gas discharging pipes. The nozzle compartment is made up as a cylinder coaxially mounted to the housing. The cylinders is provided with a nozzle. The space of the intermediate compartment is provided with horizontal by-passing plate which is coaxial to the housing additionally provided with a branch pipe for supplying blowing steam to the space. The bubbling compartment additionally has water discharging pipe with a swirler. The water discharging pipe and water drain threshold are cylinders and mounted coaxially to the housing on the bubbling sheet. In addition the intermediate and bubbling compartments are interconnected through the water discharging pipe. The jet and bubbling compartments are interconnected through vertical steam-gas discharging pipes arranged uniformly over periphery outside of the cylindrical space of the nozzle compartment. EFFECT: enhanced efficiency. |
