METHOD FOR VACUUM DEAERATION OF WATER Russian patent published in 2002 - IPC

FIELD: heat engineering. SUBSTANCE: method involves providing desorption of water-solved oxygen through contacting of basic water and heating agent in deaeration unit; removing vapor produced during deaeration process from deaeration unit by means of water jet ejector; supplying process water under pressure into water jet ejector; directing mixture of vapor and process water into process water tank of water jet ejector; discharging deaerated water from deaeration unit into accumulating tank for replenishment water; measuring content of solved oxygen in deaerated water delivered from deaeration unit. When solved oxygen content exceeds standard value, deaerated water is discharged into process water tank of ejector and directed for repeated deaeration procedure. Method may be used in boiler shop and heating and power plant. EFFECT: simplified method and improved quality of deaerated water. 1 dwg
