Abstract
The water flow circuit for a heat recovery steam generator includes both a low pressure circuit and a high pressure circuit. Both circuits are designed for once-through flow and both include evaporators with rifled tubing. A pressure equalizing header may be located between the evaporator and superheater and orifices may be located at the inlet to the evaporator for flow stability.
