APPROACH FLOW SYSTEMS WORLD PULPPAPER36 A central and deliverable aim was deaeration assuring smoother runnability machine speed over 1000 mmin Continues Lee Dai Young As part of a major paper machine rebuild a new wet end approach system was needed to address our production capacity increase goals quality and also the benefits of freeing up space in a crowded work area. HIGHER OUTPUT EFFICIENCY BASED ON SIMPLICITY A central and deliverable aim was deaeration assuring smoother runnability machine speed over 1000 mmin. AFT supplied the complete approach flow system for all three plies. None of the typical large tanks are required which allowed for the complete system to be installed on the paper machine floor eliminating the need for mezzanines. The new system includes three POMp 730 series degassers two POMheaders and three POMlock C suction leg sealing. The three POMp degassers were positioned for the back ply filler ply and top ply systems. Two POM mixing headers allow different fibres to be kept separately top vs. back. In addition to the equipment AFT also delivered basic engineering 3D conceptual engineering operator training start-up supervision and performance testing. The start-up went smoothly with the POM system handling grade testing from the minimum to maximum grammages without issue. Figure 2. Lee Dai Young Managing Director Mill Manager Korea Paper Figure 3. The POM system handles all three layers and also includes 3 POMp 730 Degassers and 3 POMlock C units
