摘要： Method and apparatus (Fig. 2) for improving the useful thermal yield of a saturated water flashed steam source (54) over a wide range of steam turbine load (32, 34, 36). A flash tank pressure control in its simplest form maintains constant steam pressure with variable input water flow (53) and inlet water enthalpy. This permits optimizing a design point relationship between water temperature, water flow, flash tank steam pressure and turbine stage pressure. If turbine stage pressure is used as a reference (128) to reduce the flash tank steam pressure (122) for part load operation, then more steam is available from a given flow of saturated water, and the throttling loss through the pressure control valve (108) can be minimized.
