VACUUM DEAERATING PLANT Russian patent published in 2000 - IPC

FIELD: heat power industry; applicable at thermal power stations and boiler plants. SUBSTANCE: vacuum deaerating plant has vacuum deaerator with pipelines of treated and deaerated water, flash steam, and ejector. The latter is connected by means of flash steam pipeline with vacuum deaerator. Connected to ejector are pipeline of ejecting medium, regulator of ejecting medium pressure which is connected to regulating member. The latter is installed on ejecting medium pipeline. Regulator of ejecting medium pressure is connected with transducer of dissolved oxygen content installed on pipeline of deaerated water. EFFECT: higher economic efficiency and quality of vacuum desorption of oxygen from water due to maintenance of optimal pressure and flow rate of ejecting medium supplied to ejector of vacuum deaerator. 1 dwg
