Paper & pulp industry: Efficient process air for demanding drying cycles
In paper and pulp production, the precise control of air flows is a crucial factor for product quality and the energy balance of the entire plant. Process air is primarily used here for the large-scale drying of the paper web, the ventilation of dryer hoods, and for heat and chemical recovery. Quality Made in Germany guarantees the necessary precision to stably support the high speeds of modern paper machines.
Challenges and risks due to moisture and fibers
The primary challenges in the paper industry are the extremely high air humidity and the loading of process air with the finest fibers and chemical residues. Without appropriate protective measures, this combination quickly leads to corrosion on housings and dampers as well as dangerous buildup on the fan impellers. Such deposits cause imbalances that result in bearing damage and massively deteriorate efficiency. Since paper machines are highly complex, integrated systems, the failure of a single fan often leads to a standstill of the entire production line, causing enormous costs due to production losses and elaborate restart processes.
Solutions and retrofit expertise: Optimizing drying efficiency
Siempelkamp Industrial Fans meets these requirements with specialized centrifugal fans made of corrosion-resistant stainless steels and high-efficiency industrial dampers that work absolutely reliably even in hot and humid atmospheres. To reduce energy costs in the thermally intensive drying sections, inlet vane controls are used, which allow for an exact adjustment of the volume flow.
In the field of retrofitting, we support paper mills in significantly increasing the energy efficiency of their dryer hoods and exhaust air systems. We modernize existing fans, independent of the manufacturer, by using flow-optimized impellers and optimize the interaction with silencers and insulation to improve heat recovery. Our full service – from characteristic curve measurement to bearing analysis – ensures maximum plant availability in continuous 24/7 operation.
