Approach

To identify the cause of the seasonal temperature increase, we conduct an analysis of the steam and condensate system. We start with a complete system analysis, including a thermographic inspection using a thermal imaging camera. During this process, Wilton discovers an unexpected heat source: a cooler is positioned in such a way that, under unfavorable wind conditions, it blows warm air towards the condensers. In effect, it acts as an unintended air preheater.

Additionally, we identify a faulty valve in a normally closed bypass line. This causes mixing of hot condensate, which further increases the temperature. Based on these findings, we propose targeted improvement measures, including repositioning of components, repair of the valve, and optimization of the maintenance regime.

Result

The combination of technical inspection, system analysis, and practical advice leads to an immediate improvement in condensate temperature control for the waste processor. They now have a more stable system, with a lower thermal load on the wastewater treatment plant. 

Total analysis of the steam and condensate system, including recommendations for future-proof modifications and maintenance strategies: the system is better able to withstand seasonal influences and operational risks.
