Abstract: The features of spiral-wound tube water wall in supercritical boiler were expounded. Some problems needing attention in the water wall design process of supercritical boiler were analyzed. The selection of key parameters in water wall design were presented which is used in 1956 t/h, supercritical, variable pressure operation, once-through boiler of Yangzhou Second Power Plant project phase II.

Key words: supercritical once-through boiler, water wall, spiral-wound tube, mass velocity, design idea
