METHOD OF WATER THERMAL DEAERATION Russian patent published in 2000 - IPC

FIELD: heat and power engineering. SUBSTANCE: method may be used in heat and power generating sets and boiler plants. Method includes desorption of carbon dioxide dissolved in water. Method is realized at contact of source water and heating agent in spray-type deaerator. Source water and heating agent are supplied to deaerator under gauge pressure. Deaerator water and flash steam formed during deaeration are removed from deaerator. Source water pressure upstream from deaerator is adjusted by preset value pH of deaerated water. Method provides for improved quality of water thermal deaeration. EFFECT: higher efficiency. 1 dwg
