Power Plant Neurath – BOA ll

In 2006, STAG received the contract of Fisia Babcock Environment GmbH to equip the lignite-fired power plant (BOA ll - RWE) in Neurath, Germany, with pneumatic conveying facilities designed for the ash removal of electric filters. Neurath is one of the most modern and powerful lignite-fired power plants throughout the whole world.

The facility is composed of the blocks F and G with 48 pressure conveying vessels in total.
Within the individual blocks, several pressure conveying vessels are grouped, these groups respectively conveying the ash in a common conveying line.

Essential Information

Applied Main Components for
•    Pressure conveying vessel  (groups of 4x6 –pneumatic hoppers per block)
•    Conveying lines to ash silo (for 4 pcs, groups 6 per block)
•    Conveying lines to ash silo (bypass line)

•    The important length of the conveying lines required a special expansion concept

•    Fisia Babcock Environment GmbH / RWE

Technical Information
Performance Data
Systems Conveying rate Conveying distance
Overall ash production from electric filter 80 t/h (per block) -
Pneumatic electric filter ash removal 14 t/h per 6 pressure conveying vessels 290 - 400m
  • Pneumatic transport of lignite ash
  • Dense phase conveying lines (Denseflow)
Bulk Material
Bulk material Grain size Moisture content Bulk density Temperature Property
Electric filter ash from lignite incineration - - 1.3 t/m³ 200°C abrasive, sandy
Appropriate Topics
Dense Phase Pipe "DenseFlow"

In conventional conveyances of powdered bulk materials through smooth pipes, the irregularity of the flow rises with the increasing pipe length. This in turn, increases the wear of the system.
