Title of Invention | HEAT RECOVERY STEAM GENERATOR |
---|---|
Abstract | HEAT RECOVERY STEAM GENERATOR 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). |
