FIELD: power engineering.SUBSTANCE: method includes enclosure of columns of spirals of steam or condensate motion areas into jackets and streamlining of turns relative to the plane of their winding, at the same time each of the columns of spirals of the superheated steam cooling area, the mass steam condensation area and heating steam condensate cooling area are enclosed into the jacket, and using transverse partitions, are divided into sections, the heating medium is supplied into the space formed by internal turns of spirals, and further along the way of steam or condensate in each section they organise streamlining of turns in spirals in the plane of their winding in direction from internal turns of spirals to peripheral ones, from peripheral ones - to internal ones, at the same time the number of spirals in the area of mass steam condensation is reduced as its flow reduces during condensation.EFFECT: increased efficiency of heat exchange in each area of a heater and its simplified design.2 dwg |
