THE IVU-FLY ASH RECYCLING SORBENT

for
dry and semi-dry desulphurisation of coal fuelled power plants
including CFB processes

• for improving efficiency within dry and semi-dry desulphurisation processes,
• for reducing the cost of lime processing,
• for reducing lime consumption by up to 50 %
• for the production of a high-quality matrix ash for DISPERGAT building material.

THE IVU-FAR SORBENT, an exceptional economic opportunity ...

• Desulphurisation is an ecological requirement demanded by law necessitating expensive plant and running cost, particularly the cost of lime powder, until now The IVU-FAR Sorbent cuts costs
  
  
• By using a special mixer, the ash to be used as a sorbent is mixed with lime granules of a grain size up to 8 min. Fine milling of lime is not necessary,
  
  
• As soon as the moistered ash/ lime mixture has entered the processing unit, the firne granules disintegrate causing an increase in temperature. In the 50 minute process the ash particles become carriers for the lime powder, thereby increasing the lime surface area. The sorbent can be stored in silos ready to be blown into the boiler.
  
  
• The increase in lime surface area enables greater desulphurisation efficiency and the quality of the lime powder can be reduced by up to 50 % dependent on the quality of the coal and the degree of desulphurisation required.
  
  
• The Sorbent Desulphurisation Process offers a basic ash for the production of DISPERGAT of very high quality which can either, be used for sorbent production again, or, as an economical and ecological building material,
