Ia/ SOx-NOx-Rox BOx (SNRB TM)

• Technology
• SOx-NOx-Rox Box (SNRB) process
• (Babcock Wilcox)
• Pollutants
• SO2 , NOx and particulates
• Process description
• Process that combines hydrated lime
• and ammonia injection upstream of hot
• catalytic baghouse (box) where the solid
• product calcium sulphite and sulphate
• and particulate (Rox) are removed, and
• the NOx is reduced to nitrogen and water .
• Implementation experience
• Location
• Dilles Bottom, Belmont County, OH (Ohio

Ia/ SOx-NOx-ROx BOx (SNRB TM)
No information is available wether this process
is actually applied to a large combustion plant.
Therefore, no information on the general
performance of the SNRB process can be given
4

Ib/ Catalytic combustion

• Technology that combusts fuel flamelessly
• Pilot scale 1.5 MWel gas turbine
• Plants for application on a 170 MWel gas turbine
  are being developed
• Nox levels of less than 10 mg/Nm3 are expected
