Sootblowers consume a significant amount of valuable high pressure steam produced by the boiler. A tremendous cost-saving alternative is to use lower pressure steam from the outlet of the steam turbine at 150 – 250 psig (10-17 bar).
RSP-H is Clyde Bergemann’s new generation sootblower designed to produce cleaning force equivalent to that of a higher-pressure sootblower. This technology enables Return On Investment (ROI) based on 350 days of annual operation and 1.5 MWhr additional green energy generation to direct all high-pressure boiler steam to a steam turbine which generates an additional 1-3 MW power, while the extraction steam from the turbine is used for sootblowing.
Four U.S. pulp mills have used Clyde Bergemann Steam Saver sootblowing technology to generate more MW and improve profitability. While initial investment is not nominal, the payoffs for this technology, even for retrofits, are extremely significant- more than enough to make the investment worthwhile.
