FIELD: the invention is designed for heat exchanging and deaeration and may be used in heat-and-power engineering.
SUBSTANCE: a mixing heat-exchanger-deaerator has a cylindrical mixing heat-exchanger with symmetric radial openings and swirling blades, a cylindrical separator with swirling blades, a socket for feeding heating steam, a socket with symmetrical radial openings for feeding water, a socket for draining of evaporation and a socket for draining of deaerator water. At that the swirling blades as of the mixing heat exchanger so as the separator are fulfilled in the shape of sections of an Archimedean spiral or an evolvent of a circle.
EFFECT: increases effectiveness of the mixing heat exchanger and separation of condensable gases.
