"desuperheating" by spraying water into steam, and others, has been developed and applied to Foster Wheeler steam generator*.
The Foster Wheeler method operates by reducing the latent heat of the steam in the superheater inlet header. It differs from con ventional desuperheating because no water
relatively cool feedwater condenses some of the entering cleaned and dried steam. The amount of moisture entering the superheater is regulated to provide positive and accurate control of final temperature. In addition to the wide range control possible when this
