Recovery Boiler - Future Prospects

Future Prospects

Recovery boilers have been the preferred mode of Kraft mill chemical recovery since the 1930s and the process has been improved considerably since the first generation. There have been attempts to replace the Tomlinson recovery boiler with recovery systems yielding higher efficiency. The most promising candidate appears to be gasification, where Chemrec's technology for entrained flow gasification of black liquor could prove to be a strong contender.

Even if new technology is able to compete with traditional recovery boiler technology the transition will most likely be gradual. First, manufacturers of recovery boilers such as Metso, Andritz and Mitsubishi, can be expected to continue development of their products. Second, Tomlinson recovery boilers have a long life span, often around 40 years, and will probably not be replaced until the end of their economic lifetime, and may in the meantime be upgraded at intervals of 10 – 15 years.

Famous quotes containing the words future and/or prospects:

    If nations always moved from one set of furnished rooms to another—and always into a better set—things might be easier, but the trouble is that there is no one to prepare the new rooms. The future is worse than the ocean—there is nothing there. It will be what men and circumstances make it.
    Alexander Herzen (1812–1870)

    A single gentle rain makes the grass many shades greener. So our prospects brighten on the influx of better thoughts.
    Henry David Thoreau (1817–1862)
