Technical Data Reference Sheet

THE TASK

Karlsruhe operates a sewage sludge combustion plant with combustion lines 1 and 2 at the Karlsruhe sewage sludge treatment plant. Within the scope of modernisation work on combustion line 2 (IL 2), the customer awarded Standardkessel Baumgarte for successful completion and commissioning. In addition to an inventory of the existing plant technology, the scope of services essentially includes the commissioning of the combustion line.

 

THE SOLUTION

During the inventory and subsequent engineering phase, we SBG has checked components for their suitability for future operation. The deficiencies found in the existing system got rectified so that we put the sewage sludge disposal system into operation with VEB 2.

The cold commissioning essentially comprised the commissioning of the supplemented and modified plant components. Completion of warm commissioning was with adjusting the plant and finally put the plant into normal operation as intended.

 

For more information, please see our reference sheet.

"The interaction of our years of experience and expertise as an EPC provider and Raschka's decades of experience with stationary fluidised bed combustion systems, complement each other to form an ideal partner for the realisation of your plant."
