Project
Power Plant Karlsruhe Block8

In 2013, a modern coal block has been put into operation in Karlsruhe. For this project, STAG was entrusted with the engineering and delivery of the mechanical and pneumatic ash removal of the electric filter. The pneumatic conveyance facility using a tandem system provides for a continuous ash removal. The preceding mechanical trough chain conveyor therefore does not operate in a “stop and go” mode but, its gentle and low-wear operation can be ensured.

 

A totality of 16 pressure conveying vessels conveys the electric filter ash to the target silos via two main lines and one redundant line. These lines have been connected by means of diverter pots. The STAG Denseflow piping system ensures low-energy and low-wear conveyance.
