A Refined Method for Designing the Staged Evaporation System of Drum Boilers With External Saline Sections and Its Application

Resumo

Arefined method for designing staged evaporation systems is developed. It allows for the design features (two symmetric sections, salt ratio line, continuous and intermittent blowdown points, etc.) of the external saline sections and the circulation conditions in the saline sections, each having two cyclones on each side of the boiler and being close upon one waterwall (circulation surge). Examples of using the method to improve the reliability of the saline sections are given.
