B&W's single-drum recovery boiler, now the standard in the industry, is continuously improved upon through the application of leading-edge technology, research and development and mill experience.
Our design features include:
- superheater, generator and economizer assemblies that are structurally stable yet minimize the use of restraints that can serve as locations for deposit accumulation and fouling
- single- and dual-sloped floors with varying elevations of smelt spouts to meet customer requirements for frozen smelt coverage of the lower furnace
- customized air and liquor delivery systems that are computer modeled for optimum lower furnace combustion, reduced emissions and long term cleanability
- customized design details to minimize maintenance throughout the life of the boiler; these features include attachments welded to non-pressure parts to minimize stress on the tubes and the potential for water side corrosion, minimal refractory usage for reduced maintenance, and tapered generator and economizer fins to eliminate cracking
- state-of-the-art furnace protection methods, including nickel alloy composite, weld overlay tubing, pin studs, and stainless steel composite
- technologically advanced drum internals and riser/supply systems for optimum circulation.
