At the same time, the blow-through steam increases (Fig. 3). Low cylinder pressures and increased production speeds often even have the result that the cylinders cannot be dewatered. As a result of the accompanying decline of the heat transfer, the drying capacity can drop massively. Steam joints with stationary siphons from Voith offer an economical alternative. They make for reliable dewatering at the lowest differential pressure. In addition, the blow-through steam does not intensify with increasing speed and remains at the lowest level when the siphon diameter is optimized. Voith steam joints are rotating siphon stationary siphon Fig. 3: Stationary siphons with low differential pressure and reduced blow-through steam provide for reliable dewatering and optimal energy requirements across the entire range of speeds. maintenance-friendly thanks to their light, compact design. The necessary replacement parts can be delivered quickly and inexpensively ex-warehouse. V plus ThermoBars For production speeds greater than 500 m/min, the condensate forms a laminar ring in the drying cylinder, which reduces the relative heat transfer of the steam to the interior wall of the cylinder. ThermoBars break up this ring by creating turbulences to create an increase in the heat transfer and drying capacity. This can increase the production speed and output. 24 26 I 2008 I Voith Paper I twogether 30 20 10 The custom planning of ThermoBar installations in selected drying cylinders creates a precise improvement 0 Blow-through steam in % in the heat transfer while improving the moisture profile at the same time. Mini ThermoBars for the edge region of the cylinder have a positive effect on moist edge strips of the paper web. Increasing energy costs reduce the efficiency of the paper industry and demand action. V plus components help to reduce energy costs, thereby securing competitive advantages.
