ABSTRACT:
A method and apparatus for providing a required deaerating temperature differential between incoming water and sparge steam in a steam generation system having a vacuum deaerator. The present invention selectively combines raising the energy of the sparge steam with flash cooling of the incoming water to provide the required deaerating temperature differential. The energizing of the sparge steam is accomplished by a thermocompression device. The thermocompression device may also be used to reduce the pressure in a portion of the vacuum deaerator to cause the flash cooling of the incoming water.
