Description
Water atomization and vaporization are key elements in any steam conditioning application. The ATST design
incorporates a manifold of patented nozzles to inject atomizing steam and spraywater into process steam. These
specialized nozzles produce an optimized spray pattern over a wide operating range. These nozzles are strategically
placed to achieve optimal mixing and quick vaporization at all flowing conditions. Years of experience with other
steam atomized desuperheater designs went into the development of this construction. Extensive use of
computational analysis, in addition to field performance feedback, was used to validate spray system performance.
