The invention relates to the branch of heat engineering intended for preparation of feeding water of heating systems, boiler rooms, systems of hot water supply and can be used in petrochemical, pharmaceutical, electronic and some branches of food industry. A stage of evaporating apparatus of instantaneous boil contains a housing 1, dividing wall 2 that divides the stage of evaporating apparatus into condensation chamber 3 with heat exchange pipes 4 and expansion chamber 5, vertical screen separator 6 with pipe 7 for removal of separated water, fixed in dividing wall 2, branch pipes 14 and 16 for supply and removal of water respectively, branch pipe 17 for removal of distillate, vertical partition 8, in upper part of which an opening A is made for passage of vapor and which is located along dividing wall 2 and forms two cavities 9 and 10 that are connected between them on the vapor in the lower and upper parts of the expansion chamber 5, moreover, the cavity 10 in the upper part is equipped at least with one channel 11 and water-distribution nozzle 12 for supply of superheated water from water-distribution chamber 15. The height of the opening A of the vertical partition 8 does not exceed the length of water-distribution nozzle 12 and makes 0.05-0.5 of the width of the cavity 9. The invention ensures the improvement of the quality of distillate and increase of productivity of the separator.
