FIELD: heat and power engineering, particularly thermal deaerators designed for removing corrosion-aggressive gases from supply water of steam generators and simultaneously heating it, possibly used in heat and power generating plants such as heat and electric power stations, nuclear electric power stations and boiler rooms. ^ SUBSTANCE: thermal deaerator includes deaeration column mounted on deaeration tank. In deaeration column low-pressure water -distributing apparatus is arranged; said apparatus is in the form of fluidic jet provided with union for supplying water. Said fluidic jet includes two mounted partially one inside other casings; each casing has outlet openings and it is provided with separate union for supplying initial water. Less -diameter casing is arranged in such a way that its outlet openings are placed lower than outlet openings of large-diameter casing. ^ EFFECT: enhanced operational reliability of water distributing apparatus and the whole deaerator at sliding pressure in wide range of heat and hydraulic loads. ^ 2 dwg |
