Changes in the pellet furnace process necessitated a divider wall be installed to achieve the required output of quality product. A number of wall designs failed, well short of the required service life of 2 years. Premature wall failure resulted in reduced (60%) production rates.
Wilbartec was assigned to investigate the repeated wall failures & liaised with all stakeholders as part of this process. From a range of recommendations, Wilbartec developed the preferred design, including a full-sized model verifying the design parameters & outcomes.
The re-designed wall was installed and commissioned with the system performing successfully, ensuring continuous production output. The client says: “ … testament to the robustness of the new wall design … is the positive feedback from the pellet plant around the performance of the wall. “
