FIELD: power engineering; water boilers with built-in deaerators. ^ SUBSTANCE: proposed boiler has water tubes of which at least one is provided with tangential water inlet. Tube provided with tangential water inlet accommodates tube of lower diameter whose open end faces plugged end of external tube; external-tube plug has central hole whose diameter is smaller than that of internal tube; this hole is used to provide communication between internal space of vortex water tube and vacuum pump inlet. Plate-type flow vortex generators are installed inside vortex water tube between cylindrical surfaces of external and internal tubes. ^ EFFECT: ability of deaeration within hot-water system proper. ^ 2 cl |
