FIELD: power industry.
SUBSTANCE: in steam generator's furnace gas channel (4) there is evaporating direct-flow heating surface (8), erranged by multiple evaporation pipes (6), and overheating surface (12), erranged by multiple overheating pipes (10) on the fluid side after evaporation pipes (12). A water segregating element (30) is inserted accordingly in multiple bypass pipe sections (20), which connect accordingly single or multiple evaporating pipes (6) with accordingly single or multiple overheating pipes on fluid side (10). Corresponding water segregating element (30) comprises connencted to mounted before it evaporation pipes (6) inlet pipe section (32), which in its longitudal direction transfers into water outlet pipe section (34). In the transition area (36) multiple outlet pipe sections (38) branch out, they are connected with accordingly further included overheating pipes (10).
EFFECT: increasing of steam generator adaptability in its start and low load modes.
