Waterwall

The use of such tempering air has diminished greatly with the shift from refractory to waterwall incinerator construction.

One important industrial example involving this phenomenon is the circumferential cracking that occurs on the waterwall tubes of some supercritical coal-fired boilers, which are fired under low NOₓ combustion conditions.

The water is heated to a steam-water mixture in the waterwall tubes of the radiant section, and the wet steam rises to the upper drum.

For greater heights, an interrupted sheet, spouts, a waterwall, or a cascade will provide a display of equal or greater visibility while affording considerable energy savings, less splash, greater wind stability, and a sound quality more appropriate to confined or interior spaces.

The design of the waterwalls provides a dramatic environment for its intended purpose as an entrance zone, bridging together the inside of the building and the Commons and park outside.

The facade of the Peggy Notebaert Nature Museum building includes a “waterwall” made of natural limestone veneer over a CMU block wall that allows surplus rainwater from the green roof to cascade down to provide water to small planting pockets; overflow water is stored in a cistern and recirculated with solar energy to irrigate the wall and provide makeup water for the created wetland in an outdoor classroom space.

One of the most dynamic features of Aria is a sweeping, all-embracing waterwall that creates a waterfall hush.
