METHOD AND DEAERATOR FOR DEAERATION OF WATER Russian patent published in 1995 - IPC

FIELD: heat engineering. SUBSTANCE: superheating is carried out in direct contact with heat carrier which is superheated to a temperature of saturation in the given compartment. Heat carrier delivery pipe 9 is connected to compartment 2 which may accommodate bubbling disperser which divides said compartment into two chambers. Deaerated water discharge pipe 8 is connected to compartment 3 while bypass channels 10, 11 communicate compartments 2 and 3 with compartment 1. In such a layout the deaerated water is superheated and expanded in absence of "cold flow" which is particularly important with the deaerator functioning under vacuum. The disperser may be made from perforated members forming, in pairs, hydraulically-sealed gas channels thus ensuring regular operating sequence of individual channels and preventing loss of water under any operating conditions. EFFECT: higher deaerating efficiency. 3 cl, 5 dwg
