Meeting your steam requirements with CONTROLLED SUPERHEAT over WIDE TOAD DANCES METHOD of superheat control which Boiler feedwater is diverted around the A successfully overcomes the disadvan* economizer and passed through tubo bundles tages of methods such as damper by-pass,located in the superheater inlet header. This "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 is added to superheated steam. Simply, device is used, superheated steam is not con superheating becomes a controlled operation taminated by water, and excessive metal from inlet to outlet stresses are avoided. A reprint ot an article describing in detail a specific application ol Foster Wheeler condenser-type superheat control is available. Ask for B-46-20.
