DEMECH has been supplying Submerged Scraper Conveyors (SSC) since 1990 and has a technical collaboration with Hitachi Power Europe, Germany to manufacture SSCs of large size which are required for the bigger boilers.
SSCs provides an ideal solution for handling hot bottom ash from coal fired boilers and hot kiln dust from steel plants. These materials which are in red hot condition when discharged are difficult to safely handle by any other means than SSC. DEMECH SSCs require less water and less headroom below the furnace. The hot Economizer Ash and the Pyrite rejects (coal mill rejects) can also be discharged to the SSC installed for handling bottom ash, which in turn saves the necessity of a separate system for these materials.
