BWE-30-0025rev.1 intersection of the outer and the intermediate radial seal plates. This new improved design constantly ensures a controlled clearance gap and a minimum air leakage of all the radial sealing plates. In order to reduce the entrained leakage caused by the rotation of the heating matrix the speed was reduced to 0.8 rpm. After the conversion the leakage has been reduced to below 5%. The total sensor control system was changed from local control panels to the DSC system of the unit in order to have a common control system for the complete equipment and all data in the main system. Installation of additional rotor measuring flanges and sensors Installation of double radial walls New heating surface including a 1,250 mm enamelled cold end layer Reduction of speed to 0.8 rpm The or
