The water flow circuit for a heat recovery steam generator (10) is a hybrid system which combines a circulating drum type circuit and a once-through circuit. A low pressure evaporator (16) is designed for natural or forced circulation and a high pressure evaporator (64) is designed for once-through flow. Orifices (68) may be located in the inlet of the evaporator tubes (64) for flow stability and an intermediate header (70) between the evaporator (64) and high pressure superheater (66) improves stability, minimizes orifice pressure drop and equalizes pressure losses between evaporator tubes (64).

Le circuit d'écoulement de l'eau de ce générateur de vapeur avec récupération de chaleur (10) est un système hybride combinant un circuit de circulation du type tambour et un circuit à passage unique. Un évaporateur basse pression (16) est conçu aux fins d'une circulation naturelle ou forcée tandis qu'un évaporateur haute pression (64) est conçu aux fins d'un écoulement à passage unique. Il peut y avoir des orifices (68) au niveau de l'admission des tubes d'évaporateur (64) destinés à assurer la stabilité du débit tandis qu'un tuyau collecteur intermédiaire, entre l'évaporateur haute pression (64) et le surchauffeur haute pression (66), renforce la stabilité, réduit au maximum les chutes de pression et équilibre les pertes de pression entre les tubes d'évaporateur (64).
