FIELD: heating systems. ^ SUBSTANCE: invention is intended for steam heating and can be used in power engineering. In fuel gas channel flowing approximately in horizontal direction of fuel gas there located is evaporation once-though heating surface of steam generator. Evaporation surface includes a lot of steam-generating tubes which are parallel connected for passage of fluid medium with many outlet headers connected on fluid medium side after some steam-generating tubes. Outlet header or each outlet header correspondingly includes integrated water-separation element through which the appropriate outlet header on steam side is connected to many superheating tubes of superheating heating surface, which are connected after it. ^ EFFECT: invention allows reduction of steam generator manufacturing cost, as well as high operating flexibility during start-up mode and in low load mode. ^ 11 cl, 1 dwg |
