FIELD: straight-through steam generators. SUBSTANCE: proposed method consists in determination of supply of feed water making use of temperature of evaporated feed water. To make certain that supply of feed water is sufficient, joint indication of actual magnitude ((Ti)) and required preset magnitude ((Ts)) of steam temperature is conducted. Device for realization of this method includes indication unit 22 with temperature dial 3- which may show actual magnitude ((Ti)) and preset magnitude ((Ts)) of steam temperature. EFFECT: enhanced reliability of check of feed water supply to steam generator. 4 cl, 1 dwg
