The Spiral Wound Universal Pressure (SWUP™) boiler - or spiral wound tube geometry UP boiler - is another supercritical boiler option available to customers.
The B&W SWUP unit is designed for both base load and variable pressure load cycling operation as well as on-off cycling operation.
The unique feature of this boiler, compared to other boilers, is that the tubes in the furnace, from the lower furnace inlet headers to a location near the furnace arch, are wound around the furnace circumference rather than being vertical. This design allows the fluid in the tubes to pass through the various heat flux zones around the furnace providing a more uniform outlet enthalpy.
B&W's spiral furnaces utilize multi-lead ribbed tubing to allow once-through operation at lower minimum loads.
