Silo unloading and metering system with pneumatic feed system

From a few kg/h to several tons/h, adapted to all chemical properties.

Our famous multi-screw conveyor, mounted in a complete metering and conveying solution under your silo

Product description

Precisely and reliably feed dry sorbents stored in silos to your flue gas scrubbing process

Sulphurous oxides, SOx, heavy metals, dioxin, furan and other pollutants are released during the combustion of fossil fuels and other substances, such as solid waste. These have to be separated out before they enter the atmosphere. This is done using a flue gas scrubbing process. One option is to add a dry reagent before the flue gas flows through the fabric filters.

Common reagents include sodium bicarbonate, calcium hydroxide and activated carbon.

The equipment provided by Tomal comprises a silo with accessories, powder metering and pneumatic transport system. The reagent is transported pneumatically and injected into the flue gas duct upstream of the filter unit.

Your benefits

  • Pneumatic bridge breaker, controlled by powder level indicator
  • Ultra-precision feeder: 1–2 % accuracy with constant bulk weight
  • Single, double and treble metering lines and more if required!
  • Friction clutch system to protect the feeder from blockages
  • Pneumatic transport system fitted on a frame, adapted to the customer’s needs
  • Can be adapted to existing or new silos

Technical Details
