The challenge

Quite a challenging job: retrofitting four boilers at different Suiker Unie locations in the Netherlands to meet the new EU emission regulations. All within a strict time schedule to be ready for upcoming sugar beet campaigns.

Stork’s solution

A turnkey approach for a complete revamp of the four boilers, including design, manufacturing, installation and commissioning of all equipment involved.

The revamp for 3 of 4 boilers have now been executed. As a result the emission measurements and ease of operation are satisfying the Suiker Unie management as well as the operators at this sugar processing company. Stork Thermeq achieved NOx-emissions values well below the targeted 70mg/Nm3.
