Challenges in pulp and paper
Many older pulp and paper mills have aged ductwork, which certainly won’t be performing at its best. The classic signs are worn-out expansion joints and old air heaters, both of which are likely to suffer leakage issues, causing problems for boiler and kiln operations.
Upgrades that are recommended and implemented can negatively affect their air handling systems, due to a new system’s volume and pressure requirements changing the operating point on the fan curve. In doing this, the fan may be forced to operate on an inefficient point on the curve, leading to excessive energy usage and increased costs for your plant.
Through our full consultation service, we can take a look at any issues you’re experiencing, and figure out how best to resolve them quickly and efficiently. Our bespoke paper mill extraction systems are built based on your requirements, so you’ll have complete control over the design.
Design considerations
A complete understanding of the existing system from undertaking a site visit is the best way to begin diagnosing and designing a contemporary solution.
The twin risks of particulate build-up and contamination may cause an explosion and system failure. Special care is needed to apply suitable materials, welding treatments, and finishes, which our team of fully trained experts are able to provide.
Solutions
Welded stainless steel type 316L is the most appropriate solution for pulp and paper applications, but it may not be suitable for all chemicals and corrosives in all environments.
Stainless steel is a risky specification if there is hydrochloric acid or nitric acid vapour present.
Galvanised steel coated inside and out with a 4 mL thick coating of polyvinyl chloride, or a corrosion-resistant epoxy coating, may be an acceptable material for fume exhaust ductwork.
