Flue gas scrubber

Lime and fly ash silo

Lime for the production of lime milk for flue gas desulphurization must be stored in silos. The fly ash filtered out of the flue gases must also be stored in large silos. Silo heights of up to 60 m are not uncommon. Depending on their composition and consistency, the media has a tendency to adhere to system equipment. A reliable level measurement is thus absolutely essential for trouble-free storage and material planning.

Level measurement in the fly ash silo with VEGAPULS 68

The ash particles in the flue gas are filtered out with large electrostatic filters and stored in part in very large silos. In those silos that can be up to 75 m high, non-contact measurement of the contents with a VEGAPULS 68 radar sensor is the ideal solution. All types of fly ash can be measured reliably with it.

Level measurement in the lime silo with VEGAFLEX 61

Due to extreme dust generation during filling and fluctuating moisture content, the microwave measuring technique is ideally suited for level measurement in the lime silo. The VEGAFLEX 61 is a simple and cost-effective solution for containers up to 15 m height. To avoid the excessive loads on silo roof and measuring equipment that are associated with higher silos, the implementation of a non-contact measurement setup with VEGAPULS 68 is recommended.
