0The Ecomaine WtE plant in Portland/Maine uses a mobile DD-Jet system for improved boiler cleaning and avoiding excessive boiler fouling. This plant has a Steinmüller boiler from 1986 with a width of 3,6 m. One opening per boiler pass in the boiler roof is sufficient to clean the entire pass.
The DD-Jet technology allows to remove deposits on the membrane wall tubes of open boiler passes (typically first, second and third pass). The result is improved heat transfer and reduced flue gas temperatures. This also leads to improved operation conditions at the convective boiler passes and superheaters. Desired consequences are longer service periods, increased availabilities, reduced corrosion and potential for higher throughput.
